cannot get sendmail working

I believe I have a fairly vanilla mail setup and i've installed mail servers before, but I guess I'm losing my touch. I am using sendmail version 8.14.4 on Linux slackware distro 13.37.0, kernel  2.6.37.6-smp.

The following is my .mc file for creating sendmail.cf:

The domain is hosted at network solutions. mail.cantleysauto.com points to the correct IP and there is an MX record for mail.cantleysauto.com.

The host is behind a router and the router definitely port-forwards port 25 to this host.

I tried sending a message from the account: mfoley@cantleysauto.com to mfoley@novatec-inc.com. The following is the /etc/maillog output:

Where would I find this? I don't see any "authentication" setting in sendmail.rc or the original .mc file.

amit_panjwani: > seems like you need to fix host file.

I added to /etc/hosts:  192.168.2.100         mail.cantleysauto.com
and I still got errors as shown below. I changed the IP in hosts to be the actual public IP and was back to the  error: "gethostbyaddr(192.168.2.100) failed: 1"

This may be the right track though. I think what I need is the public IP, right? Is it possible the remote servers are trying to connect to 192.168.2.100?

It says, "accepted for delivery", but doesn't make it to the other end. Maillog on the "bad" computer has:

jmarkfoleyAuthor Commented:
Enphyniti: > Are you getting DNS resolution?  

While I am sure this problem has something to do with "resolution", I can't figure out what. From a remote host I get:

> nslookup mail.cantleysauto.com
Server:         65.24.0.168
Address:        65.24.0.168#53

Non-authoritative answer:
Name:   mail.cantleysauto.com
Address: 108.66.178.47

Which appears correct. From the local mail.cantleysauto.com host I get:

nslookup mail.cantleysauto.com
Server:         192.168.2.254
Address:        192.168.2.254#53

Non-authoritative answer:
Name:   mail.cantleysauto.com
Address: 108.66.178.47

However, this is a bit of a fudge since the local /etc/hosts file contains:

108.66.178.47   mail.cantleysauto.com mail

The real local IP of this machine is 192.168.2.100. I suspect this has something to do with the problem since this is the first time I've tried setting up a mail server from a port-forwarded machine with a local IP address versus a public IP.

Enphyniti: > Do you have valid name servers configured on this system?

The /etc/resolv.conf file has:

nameserver 192.168.2.254

which is the local IP of the cable-modem/router. There appears to be no problem resolving names from the MAIL host.

Enphyniti: > I sent a test message to postmaster there.  Did you receive it?

Yes, sort of. The message is included below. It has, "permanent fatal errors", "MX list for cantleysauto.com. points back to mail.cantleysauto.com" and "Local configuration error". No doubt these indicate the problem, but I don't know what or how to fix it. The MX record is hosted at network solutions and does point to 108.66.178.47, which is what I think it *should* do.

Thanks for you help!

That did help. I added mail.cantleysauto.com and cantleysauto.com to /etc/mail/local-host-names. Now, mail sent to that domain is delivered. That's half the problem. However, I still cannot send mail *from* that domain. Since the main purpose of this host is to send mail OUT, I'm still pretty stuck. Here is the maillog from an attempt to send from mfoley@cantleysauto.com to mfoley@novatec.com:

As you can see, I get an "accepted for delivery" message. Then, a little over 5 minutes later, I get a Connection timeout out" message.

Here's another with trying to send to hotmail.com:

That's all I get, no connection timeout.

Here's an interesting bit. Notice the "[76.181.75.238] did not issue MAIL/EXPN/VRFY/ETRN during connection". that message repeats every 10 minutes. What is that? Tracking down that IP (http://www.yougetsignal.com/tools/web-sites-on-web-server) indicates that it is my HOME ROUTER!!! I've searched all over this host for that IP and I cannot find it specified anywhere. The A and MX records at Network Solutions are as follows:

A and MX records
That IP is not referenced anywhere. Now, once upon a time I did have this domain pointing to my home computer for testing, but that was quite a while ago, weeks. What's up? Could this be part of my problem?

> That IP is not referenced anywhere.

I figured out the "... did not issue MAIL/EXPN/VRFY/ETRN during connection" message. That is simply from a remote computer that telnets to port 25 every 10 minutes just to make sure the local computer is still up. So, that message is a non-issue. Still having problems with sending mail FROM this host.

Open in new window


You can see that not quite 6 hours after sending the message I get the "could not send for past 4 hours" message. The sender's mailbox gets a message with:

<jmarkfoley@hotmail.com>... Deferred: Connection timed out with mx1.hotmail.com.
Warning: message still undelivered after 4 hours
Will keep trying until message is 5 days old

/etc/mail/local-host-names has:
mail.cantleysauto.com
cantleysauto.com

/etc/mail/access has: (#comments are not in the actual file)

more info:

I tried telneting from my problem host to other hosts. E.g.:

telnet webhost1.fluxrunner.com 25
Trying 96.11.168.99...
telnet: connect to address 205.178.146.50: Connection timed out

However, I could telnet to ports 80 and 22 w/o problem. What does this mean? Is the ISP blocking 25? Is there a problem with my configuration?

Come on folks!!! Is no one interested in this question!?!?!?

more info: Likewise with other (Windows) hosts on this LAN. I can telnet to ports 80 and 22, but not 25. So, wassup? firewall? ISP? ... ?

Weird...  205.178.146.50 is a network solutions email server.  Why would your telnet request be attempting to go there?

I think that must have been a copy/paste error when I pasted the results into EE I tried this to LOTS of hosts. I ran it again just now and got more expected results:

telnet webhost1.fluxrunner.com 25
Trying 96.11.168.99...
telnet: connect to address 96.11.168.99: Connection timed out

If  205.178.146.50 was the actual IP from the error message in posting ID: 38397619, I can't explain it. The MX record for this host is at Network Solutions; maybe that could have something to do with it?

Anyway, any ideas why I can't telnet out to port 25 on this computer, or other computers on this LAN? I can telnet out using other ports and I can telnet into port 25. I think this is my problem.

Problem solved. It turned out to be the ISP blocking outgoing port 25. The ISP is sbcglobal. None of the other local providers I tested block 25-out: roadrunner, TWtelecom, Wowway. After trying everything on the router I could think of (including disabling all firewalling) I finally called sbcglobal. They enabled the port and all is well.

Adding the local hostname and domain name to the /etc/mail/local-host-names file did the trick with my configuration setup and allowed me to receive mail. Otherwise, the configuration was OK. There's nothing we could "configure" to get the ISP to unblock port 25.
