Zimbra send and receive mail

I have installed Zimbra Collaboration Suite 6.06 on Centos 5.4. Before installing I created DNS and MX records at godaddy's domain manager.

domain name:     mydomain.com
mailserver:          mymail.mydomain.com  (mx record)
mailserver host name:   mymail

the hosts file is
#       localhost.localdomain   localhost
(mypubliciP)   mymail.mydomain.com   mymail

Since this is for evaluation purposes, It is public IP with out any firewall.

I can send & receive emails within (mydomai.com) users.
I can send email to ***@gmail.com
I cannot send email to anyone else. I have tried  ***@hotmail.com,  ***@me.com

When I compose a messege and hit send it seems to go. "Messege Sent", but I do not receive it on my hotmail.com and me.com accounts. When i send mail from outside to mine@mydomain.com  I do not get it.

I check in zimbra log file. I was not able to understand what is going on.
I have attached some code.

Please help.

From what I can see your setup seem fine exept youre reverse dns

Your zimbra ip is probably = which does NOT reverse to your zimbra hostname

nslookup gives :
...      name = 173-162-210-205-NewEngland.hfc.comcastbusiness.net.

So my assumption is that hotmail and other are putting your email in spam because of this.   But Gmail use a different approch to tagged spam that's why is goes to gmail no problem.

This log entry confirm that email going to hotmail leaves your server correctly and is accepted by a hotmail server.

Hello Bougui,
    Thanks for such valuable information. Where do i make this change. Where does the change need to be done at the godaddy, comcast or my server. When you look up mx domain record for mydomain.com it comes correctly.

Your mx resord are you to reveived mail your reverse dns record are used by server that accept or reject email from you.

This is at your provider comcast which should resolve your public ip to myzimbrahost.mydomain.com

When this will be done you should be able to do a nslookup which will return your hsotname instead of comcast default nams

"Reason: Illegal host/domain name found"

You have at least 2 problems

your hosntname have no a record

do  nslookup mymail.mydcser.. externnally and nothnig will show up.  Mx recrod are nice but you need the corsrespondig a record for it ;-)

After that things should come ok.

let me know

   Thanks bougui for helping out so much.
  I do nslookup and it resolves to

> nslookup   mymail.myvdc...com

Non Authoritative Answer
Name:  mymail.myvdc...com

other thing I notice is when I send  an email as a reply to old message it goes to my hotmail account., but when I compose a new message it does not get there. Getting confused.  

maybe it work from where you are but from here in montreal outside of youre network it does't not to you still have dns issue

dig mymail.mydcserver.com.

Wont return an ip


dig www.sun.com

You will get an ip

Dig will go ask mydcserver.com. dns server directly

Until this is fixe you will have incoming email problem.

Cheer !

hello bougui,

   Thanks.  On your first reply I thought if was  a typo.  the address is

and the main domain is    "myvdcserver.com"

Please try and tell me if you are not getting what is expected.
Ha ha

there it is

your mx record is wrong

myvdcserver.com      mail exchanger = 10 mymail.mydcserver.com.

shoulld be

myvdcserver.com      mail exchanger = 10 mymail.myvdcserver.com.

It sould help you out a lot ;-)

going to change that right now. What a joke. I must of ran this nslookup comand 100 time but never noticed it.

DigitaleyeAuthor Commented:
Thanks! what a relief. Everyone is working.

Only hotmail is not getting it when i compose a new email hotmail does not get it, but  when I hit reply hotmail gets it right away.  

it is working for the the rest.  Thanks alot again.
Maybe a typo in the email address when you compose ? ;-)

Also it may be related to your reverse ip not live in hotmail DNS yet.

I a couple of days it should be fine.

Can you close this issue.
