Email not sending/receiving

I setup a new server over the weekend, Centos 6.4 and am having issues with email. I read a bunch of email related topics in the forums for others with Postfix issues but still unable to fix.

email sent from the server: (/var/log/maillog) Jun 3 13:11:35 srv02 postfix/pickup[25846]: 2130E29316E1: uid=0 from= Jun 3 13:11:35 srv02 postfix/cleanup[28082]: 2130E29316E1: message-id=<1370279495.28078@domain.com> Jun 3 13:11:35 srv02 postfix/qmgr[5267]: 2130E29316E1: from=, size=598, nrcpt=1 (queue active) Jun 3 13:11:35 srv02 postfix/trivial-rewrite[28083]: warning: do not list domain hostname.net in BOTH mydestination and virtual_alias_domains Jun 3 13:11:35 srv02 postfix/trivial-rewrite[28083]: warning: do not list domain hostname.net in BOTH mydestination and virtual_alias_domains Jun 3 13:11:35 srv02 postfix/local[28084]: 2130E29316E1: to=, orig_to=, relay=local, delay=0.03, delays=0.02/0.01/0/0.01, dsn=5.1.1, status=bounced (unknown user: "admin") Jun 3 13:11:35 srv02 postfix/cleanup[28082]: 26FD329316E2: message-id=<20130603171135.26FD329316E2@srv02.thegauntlet.net> Jun 3 13:11:35 srv02 postfix/bounce[28085]: 2130E29316E1: sender non-delivery notification: 26FD329316E2 Jun 3 13:11:35 srv02 postfix/qmgr[5267]: 26FD329316E2: from=<>, size=2489, nrcpt=1 (queue active) Jun 3 13:11:35 srv02 postfix/trivial-rewrite[28083]: warning: do not list domain thegauntlet.net in BOTH mydestination and virtual_alias_domains Jun 3 13:11:35 srv02 postfix/qmgr[5267]: 2130E29316E1: removed Jun 3 13:11:35 srv02 postfix/local[28084]: 26FD329316E2: to=, orig_to=, relay=local, delay=0.04, delays=0/0/0/0.04, dsn=2.0.0, status=sent (delivered to command: /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME) Jun 3 13:11:35 srv02 postfix/qmgr[5267]: 26FD329316E2: removed

Email being sent to me bounces back:

Delivery to the following recipient has been delayed:

 user@domain.com

Message will be retried for 2 more day(s)

Technical details of temporary failure:

MX Record:
HOST NAME MAILSERVER HOST NAME MAIL TYPE MX PREF TTL
@ domainname.com. MX 3600
mail domainname.com. MX 3600

It is the same MX record setup I used from the cpanel server I was migrating from, no changes made. I installed virtualmin from install.sh. Any help would be greatly appreciated.

The key line here seems to be this:

“postfix/trivial-rewrite[28083]: warning: do not list domain hostname.net in BOTH mydestination and virtual_alias_domains”

This can be a bit tricky to debug, and too complex for advice without direct analysis. So I can offer to take a look at your Virtualmin system myself, if you trust me with your root login. Feel free to post some contact info (instant messenger preferred) here if you’d like that!
