Mail not being received... logs and details included.

[cjhall]

All:

I have zimbra installed on Redhat Fedora Core 4. Mail is being sent fine. Mail is not being received!

Let me give you the network topology first.

Linux Redhat FC4 firewall server at static IP 71.xxx.xxxx.xxx. Behind it is my mail/zimbra server. I use iptables to route port 25 to my mail server.

The zimbra box, mail.mydomain.info, has internal ip 192.168.0.10. There is a MX record for mail.mydomain.com pointing to the 71.xxx.xxxx.xxx ip.

/etc/hosts on mail is:

127.0.0.1 localhost.localdomain localhost
192.168.0.10 mail.mydomain.info mail

hostname on the mail/zimbra server is 'mail.mydomain.info'

So I sent a test email to an account that I have created, say me@mydomain.info.

The log below gets the mail but tries to resend it to mail.mydomain.info using the 71.xxx.xxxx.xxx ip????

I'm confused as to why mail isn't being delivered. I think I have provided all the relevant logs.

Please tell me what I have misconfigured or what I'm missing. THANKS for a tremendous product!!!

Mar 25 09:24:16 localhost postfix/lmtp[10228]: CA8139F06E2: to=, relay=none, delay=1, status=deferred (connect to mail.mydomain.info[71.xxx.xxxx.xxx]: Connection refused)

Notice this says LMTP which means it's postfix trying to deliver the mail to zimbra via lmtp on port 7025. postfix will always use DNS. So your DNS looks to be resolving mail.mydomain.info -> 71.xxx.xxxx.xxx.

Two ways to fix this. Set up split DNS so the internal DNS request from postfix gets the 192.x.x.x address.

or if you want a less secure hack open 7025 on your firewall to allow postfix to come in via the 71.x.x.x address and deliver. If you set the rule to only allow the localhost it'll be more secure and will keep your 7015 port hidden from the internet.

Thanks for the reply.

I'm sorry, I don't know how to do this...
"Set up split DNS so the internal DNS request from postfix gets the 192.x.x.x address."

Would you please advise?

THANKS so much!
