Outbound mail stuck in deferred

[gchino]

Hi Everyone,

I'm not sure what I need to provide you guys to help me out but I want to say Im new to this and everything was working up until a week ago. I recently noticed that my ipaddress was blacklisted but was recently removed. Mail is still not going out but I am able to receive from external and send mail internally. What information do you need to help me out?

Thanks in advanced!

Do you get any bounce email from external mail servers? Are you sure you are not listed anywhere else?

[gchino]

No I do not get any bounce email. I just see all email stuck in the deferred mail in admin console. I also verified at mxtoolbox that I am no longer black listed.

[gchino]

I really need help with this. I have email that has been stuck in the deferred mail for over a week now.

I'm looking in my deferred mail queue and the error message that is being displayed is that host or domain name not found. Any suggestions on this?

Yes, your DNS is likely to be set-up incorrectly. If you're behind a NAT router then check the Split DNS article in the wiki.

You don't actually give us much information to help you debug this problem, some idea of operating system, Zimbra version, what you've done to try and debug this issue (this has been covered many times, have you searched the forums?) or even what's changed to likely cause this problem.

How about posting the info from the following commands (run on the zimbra server):

host `hostname`  <-- type as-is with backticks not single quotes
dig yourdomain.com mx 
dig yourdomain.com any

post the exact output from those commands.

Phoenix thanks for getting back to me. To answer your questions

OS - Fedora7
Zimbra version - 4.5.6
I tried to follow all of the forums in zimbra that relate to my error messages but still nothing.

I tried to do what you request with host `mail.sleepex.com` but I get command not found.

Here are my results for the dig

Phoenix,

I tried this line host 'mail.sleepex.com' and this was my return message
mail.sleepex.com has address 70.91.46.20.

I hope this information help you to help me out.

Thanks in advanced.

None of the output you've posted is actually what I asked for, you've used the FQDN of your server not your domain name for the commands. Do them again as I asked:

host `hostname`   <-- this command should be typed exactly as you see it here. Do NOT put your hostname in there,  copy/paste it to a terminal and run it.

dig sleepex.com mx 
dig sleepex.com any

Are you also behind a NAT router? Is there any firewall or SElinux enabled on this server?

[gchino]

Sorry,

Here are the results

[root@mail ~]# host `hostname`
mail.sleepex.com has address 70.91.46.20
[root@mail ~]#


Yes we are behing a nat router. Firewall and SElinux is disabled.
