how to configure sendmail for mail server host in virtual domain lan
In the past I have configured a dedicated linux host to act as a mail server in a LAN configuration. Now, I need to do something similar (dedicate mail host), but I have several hosts in the lan each hosting several virtual domains. I want the mail server to route incoming mail to the appropriate host. I can easily configure Network Solutions to send the various domain's email to this one host. I'm sure this is a pretty typical configuration for ISP setups, but it's new to me. I need lots of help!
In the code snippet below is a sendmail.mc file (sans-comments) I've used as a templae in the past. Perhaps this is a good starting point.
What do I need to do to make this work on my mail server given the configuration I've spacified.

Configure the mailertable:
mydomain.com esmtp:other.smtp.server.co
makemap hash /etc/mail/mailertable < /etc/mail/mailertable
mydomain.com esmtp:other.smtp.server.co
makemap hash /etc/mail/mailertable < /etc/mail/mailertable
OK, I've set that up as:
virtual.com esmtp:[host1.mydomain.com]
Now for upstream ... At Network Solutions I can set up A records, MX records and CNAME records. So, if I have domain mydomain.com and mail.mydomain.com is on 200.200.200.1, and virtual.com is a virtual domain being hosted on host1.mydomain.com at IP 200.200.200.5, would I:
A: @mydomain.com -> 200.200.200.1
A: mail.mydomain.com -> 200.200.200.1
A: @virtual.com -> 200.200.200.1
MX: mydomain.com -> mail.mydomain.com
MX: virtual.com -> mail.mydomain.com
Do I need an A record for mail.mydomain.com or does the MX record take care of that?
Would I do anything with CNAME (host alias)?
virtual.com esmtp:[host1.mydomain.com]
Now for upstream ... At Network Solutions I can set up A records, MX records and CNAME records. So, if I have domain mydomain.com and mail.mydomain.com is on 200.200.200.1, and virtual.com is a virtual domain being hosted on host1.mydomain.com at IP 200.200.200.5, would I:
A: @mydomain.com -> 200.200.200.1
A: mail.mydomain.com -> 200.200.200.1
A: @virtual.com -> 200.200.200.1

MX: virtual.com -> mail.mydomain.com
Do I need an A record for mail.mydomain.com or does the MX record take care of that?
Would I do anything with CNAME (host alias)?
You need an A record for the MX fully qualified domain name (which you have as listed above).
List the MX for both domains as mail.mydomain.com.
Don't use "@virtual.com" with the same A record as mydomain.com -- use its own IP address.
I am not a fan of "@domain" in DNS.
I list an A record for every MX host, an A record for the machine and CNAME records for hosts that have the same IP as the machine:
mydomain.com. IN MX 10 mail.mydomain.com.
ns.mydomain.com. IN A 200.200.200.1
mail.mydomain.com. IN A 200.200.200.1
www IN CNAME ns.mydomain.com.
smtp IN CNAME ns.mydomain.com.
and
virtual.com. IN MX 10 mail.mydomain.com.
ns.virtual.com. IN A 200.200.200.5
www IN CNAME ns.virtual.com.
smtp IN CNAME ns.virtual.com.
You need to configure a DNS record for every host that needs to be reachable with a hostname.
mail.mydomain.com should have a PTR record in the inverse database that matches the address listed in the forward zone.

I've configured the DNS settings at Network Solutions as follows. See if I've grasped what you've said:
A records:
www.mydomain.com 200.200.200.2 # web server different than mail server
@.mydomain.com [deleted per your advice]
mail.mydomain.com 200.200.200.1
allothers .mydomain.com 200.200.200.2
www.virtual.com 200.200.200.5
@.virtual.com [deleted per your advice]
mail.virtual.com 200.200.200.1
allothers . virtual.com 200.200.200.5
MX records:
(for mydomain.com) 10 mail.mydomain.com
(for virtual.com) 10 mail.mydomain.com
I'm not really sure what to do with the CNAME records right now. So far, I have 3 hosts: mail.mydomain.com, host1.mydomain.com and host2.mydomain.com. host1 hosts virtual.com and host2 hosts mydomain.com. I have no additional virtual domains (yet).
Do I need the mail.virtual.com A record? Your example doesn't specify that.
Finally, since I only have 3 hosts at the moment, I have not configured DNS. Instead, I'm using /etc/resolv.conf and /etc/hosts. I was trying not to introduce too many variables at once into this exercise. I intended to configure DNS after getting the mail running. Bad idea?

I'm starting to get lost here. Now, ssh is not working. Here's my setup:
mail.myhost.com 200.200.200.1
host1.myhost.com 200.200.200.5
host2.myhost.com 200.200.200.2
before doing the above I had the Network Solutions routing www.virtual.com to 200.200.200.5 and (allothers).myhost.com also going to 200.200.200.5. So, I could: ssh myuser@myhost.com and it would end up on 200.200.200.5 i.e. host1.myhost.com.
After doing the setup in my previous post, (24904376) ssh is not working (but www is still working). I think I'm getting lost.
mail.myhost.com 200.200.200.1
host1.myhost.com 200.200.200.5
host2.myhost.com 200.200.200.2

Presuming that the actual machine names are "host":
host.mydomain.com -> A -> 200.200.200.1
mail.mydomain.com -> A -> 200.200.200.1
mydomain.com -> MX -> mail.mydomain.com
www.mydomain.com -> CNAME -> host.mydomain.com
host.virtual.com -> A -> 200.200.200.5
myvirtual.com -> CNAME -> host.myvirtual.com
virtual.com -> MX -> host.mydomain.com
The important point here is that you identify where the host application resides.
If ssh isn't working, verify that the hostname, that you were ssh'ing to, has not changed in DNS.
If you could give an example of real domain names, what users do with what machine (*), we could probably correct this immediately.
* send out email
download email
ftp files
www pages
... etc
host.mydomain.com -> A -> 200.200.200.1
mail.mydomain.com -> A -> 200.200.200.1

www.mydomain.com -> CNAME -> host.mydomain.com
host.virtual.com -> A -> 200.200.200.5

Those pretty much are the real names, but with genericized domains. I suppose it's not that critical a security issue though, so here are the real everthing:
Machines:
mail.fluxrunner.com 96.11.168.100
webhost1.fluxrunner.com 96.11.168.99
webhost2.fluxrunner.com 96.11.168.102
webhost1 will host virtual domain www.courtscan.com, plus others in the future.
webhost2 wil host www.fluxrunner.com.
I want mail.fluxrunner.com to route mail for user@courtscan.com to webhost1 and mail for fluxrunner.com to webhost2.
That's pretty much what I need at the moment. If I can get those set up I think it should be easy enough to clone the idea for additional virtual domains and hosts.
I thought it could send courtscan.com ssh users to webhost1 via: "ssh user@courtscan.com", but if I can't do that and I have to do "ssh user@webhost1.fluxrunner.c
I am all set on the www virtual hosting via apache/tomcat, I just need the mail routing correctly.
See if that covers what you asked. Meanwhile, I'll try out your A/MX/CNAME suggestions.

Actually, you can ssh to courtscan.com if there is an A record of 96.11.168.99 or a CNAME record of webhost1.fluxrunner.com in the DNS database for courtscan.com
courtscan.com. IN CNAME webhost1.fluxrunner.com.

Sorry, but I keep getting confused on your recommendations:
> host.mydomain.com -> A -> 200.200.200.1
> mail.mydomain.com -> A -> 200.200.200.1
> mydomain.com -> MX -> mail.mydomain.com
> www.mydomain.com -> CNAME -> host.mydomain.com
> host.virtual.com -> A -> 200.200.200.5
> myvirtual.com -> CNAME -> host.myvirtual.com
> virtual.com -> MX -> host.mydomain.com
host.mydomain.com and mail.mydomain.com are different machines, but maybe I confused you with the "fake" domains and IPs. Why is your the MX for mydomain.com going to mail.mydomain.com, but the MX for virtual.com is going to host.myvirtual.com? Shouldn't it be going to mail.mydomain.com as well (I have only one mailserver)? You have a CNAME for www.mydomain.com to host.mydomain.com, but there is no "www" prefixed on the CNAME for myvirtual. Finally, I don't really have a host.virtual.com, do I?
Perhaps we should just start clean with you using my REAL domains and IPs per my previous message.
Also, attached is an image of the Network Solutions CNAME form. I am having difficulty connection your CNAME configs with this form. What goes in "alias"? What goes in "Refers to hostname"?

btw - I sent that last message before receiving your most recent message. It is not a commentary on 24935831, but rather on 24910217. I will digest 24935831 and try out suggestions.
The above example is accurate. What I was referring to in the 'fake' example, was the use of an address record for courtscan.com.
You could have written it as:
courtscan.com.db
courtscan.com. IN MX 10 mail.courtscan.com.
mail IN A 96.11.168.99
Based upon actual information, I would suggest that you stick with:
courtscan.com.db
courtscan.com. IN MX 10 mail.fluxrunner.com.
fluxrunn.com.db
fluxrunner.com. IN MX 10 mail.fluxrunner.com.
mail IN A 96.11.168.100
webhost1 IN A 96.11.168.99
webhost2 IN A 96.11.168.102
--------------------------
What we have done:
* identified the address (A) records for each machine
* identified the host address (A) for the inbound mail server
* identified the mail exchange (MX) for courtscan.com and fluxrunner.com
* configured sendmail to forward incoming email on mail.fluxrunner.com to the appropriate servers
* added the hosts that are local to each server in the mail local host file
Does that help clear things up?

OK, Here's what I've got so far...

I have no CNAME records.
sendmail for mail.fluxrunner.com and webhost1.fluxrunner.com is configured as shown in the snippet below. At the moment, nothing is configured in the access.db's
BUT ... so far mail is not working quite right
if I send something to an external email address (mfoley@novatec-inc.com) from a user account on mail.fluxrunner.com it goes straight to the dead.letter folder. The /var/log/maillog file says " <mfoley@novatec-inc.com>..
If I send something from webhost1.fluxrunner.com to an external email address it does deliver it, albeit with a From: address of user@webhost1.fluxrunner.c
If I send something to user@courtscan.com from an external host it bounces with "550 5.1.2 <mfoley@courtscan.com>... Host unknown (Name server: courtscan.com: no data known)"
If I send something to user@webhost1.fluxrunner.c
So, I still need a bit of work on this!

> 1) courtscan.com is not configured with an MX record
Well, I think I do have courtscan.com configured with MX to mail.fluxrunner.com. In my message 24949664 I say I have an A record for mail.courtscan.com -> 96.11.168.100 (which is really mail.fluxrunner.com) and MX for courtscan.com -> to mail.fluxrunner.com.

I've changed esmtp to smtp and removed the brackets as well. My mc file specifies:

I created /etc/mail/mailertable.db using: make mailertable, but I have just now re-hased it using your makemap hash syntax, just in case.

I am using resolv.conf on my hosts and using network solutions as a remote dns resolver. If you think I need to set up DNS first on my hosts, I'll do that, but I was hoping to defer that task until later.

re: novatec -> I can see that today. Yesterday there was no answer.
I believe I've made the mods you suggested. I'm not sure your dig output tells me anything I can figure out.
When I send an email from mfoley@novatec-inc.com to mfoley@courtscan.com I get the following error at novatec:
550 5.1.2 <mfoley@courtscan.com>... Host unknown (Name server: courtscan.com: no data known)
The /var/log/maillog on mail.fluxrunner.com appears to have nothing at all from this attempt. So, it seems that the message is not even getting to mail.fluxrunner.com.

What this means is that under the courtscan.com DNS entries, there is no A record for the domain (and also no MX record).
Log back into NetSol's website, DNS management, choose courtscan.com and add the A, CNAME and MX records suggested.
Log back into NetSol's website, DNS management, choose courtscan.com and add the A, CNAME and MX records suggested.
I've posted a screen image of the network solutions configuration page for courtscan. I've added lines and ellipses in red to highlight what I think are the germain entries. I believe I do have A and MX records configured. If I have these wrong, please let me know.
I still don't have any CNAME records. I was not able to extrapolate from your DNS database format to the netsol form which I posted in message 24935860.
If what I am trying to do is not possible using netsol's DNS service, perhaps I should configure my own?

Looks good to me. What DNS servers are authoritative (listed) for courtscan.com? I'd like to query them directly.
Through Network solutions courtscan.com's domain name servers are set to:
NS39.WORLDNIC.COM
NS40.WORLDNIC.COM
All the local fluxrunner.com hosts have the following entries in /etc/resolv.conf:
nameserver 65.24.0.168
nameserver 65.24.0.169

I added an A record for @(none) as 96.11.168.100 (see image in comment 25009333). The 'dig' results are shown below. I think we've improved, but not quite there. When I send a message from novatec-inc.com to courtscan.com I get the following bounce on novatec-inc.com:

1) courtscan.com A record now appears. you need to also add the MX record. I don't use @ at all. it swallows stuff up that it shouldn't. if you set the A, CNAME, MX and NS records for the hosts as recommended, i think everything will work fine.
2) novatec-inc.com -- this is a problem with the originating machine not resolving novatec-inc.com. from which machine is this mail being sent?

Wow, this is being much more difficult than I thought ...
1) All I did to make the courtscan.com A record appear with the 'dig' is that I added the @ record. So, not using it at all doesn't seem to work.
2) The originating machine *is* novatec-inc.com, so it can't be that machine that is not resolving. I send and receive hundreds of emails from that machine every day. I've also put the novatec-inc.com IP into mail.fluxrunner.com's /etc/hosts file to no effect.
I can try the CNAME thing, but I'm not sure of the configuration. What is the host name? What is the alias name? Is it:
Alias Host
----------------------- --------------------------
mail.courtscan.com -> mail.fluxrunner.com
Since our changes on July 27th I have there is zero in the /var/log/maillog file on mail.fluxrunner.com. I've even rebooted in case the sendmail wasn't running.

I still don't see a configured MX server for courtscan.com
And this bothers me:
"Unrecognized host name novatec-inc.com."
It's complaining about novatec-inc.com -- not courtscan.com.

working offline would be fine. How do we do that? My email is already all over this question: mfoley@novatec-inc.com. Meanwhile, I'm going to try to get normal, non-virtual email working with fluxrunner.com. I've accomplished such setups in the past. Then maybe we can add the virtual domain.
And add in /etc/mail/access for mail.fluxrunner.com:
To:courtscan.com RELAY
Once the MX record for this domain is visible via a dig, mail to this domain should work.

jesper - I'm posting my final results from our offline correspondence. This, plus your suggestion in 25060028 seem to have done the trick. Thanks
--------------------------
I think I have things working now! Now all I have to do is get specified sers on webhost2.fluxrunner.com to masquerade as user@courtscan.com. I'll research that and make that a separate post if necessary.
So, here is the total configuration for virtual hosting. Perhaps you can
copy/paste this to a response on EE and I can give points:

THAT'S IT! I've not included the configuration for webhost2 since it is
basically the same as webhost1 except no courtscan.com in
local-host-names.
--------------------------
I think I have things working now! Now all I have to do is get specified sers on webhost2.fluxrunner.com to masquerade as user@courtscan.com. I'll research that and make that a separate post if necessary.
So, here is the total configuration for virtual hosting. Perhaps you can
copy/paste this to a response on EE and I can give points:
