Postfix not honoring email aliases for local delivery
 

I have a hosting server, configured as per the Perfect Setup (Opensuse 10), with ISPConfig installed. Everything seems to be working - uptime has been over a month, now, with the only problems I've had so far being domain registration hiccups which have nothing to do with my server.

However, one of my customers is testing a web order form, and I've run into a problem: while emails incoming from outside servers work fine, local deliveries don't seem to be using email aliases properly.

Eg.

Username: example.admin
Primary email: example.admin@example.com
Alias: info@example.com

If I send an email to info@example.com from outside, it works without a problem. If I send it from an another domain also hosted on the site, admin@example2.com, it bounces back with the following error:

I checked all the threads on Postfix problems I could, and the following have already been ruled out:

- The server's FQDN is main.example.com
- The $myhostname parameter in main.cf is main.example.com
- main.example.com is not used as a virtual domain for any email or web services. www.example.com and example.com are, however.
- All DNS entries are correct. Again, outside email works fine with the alias rewriting.
- alias_maps = hash:/etc/aliases
- virtual_maps = hash:/etc/postfix/virtusertable
- mydestination = /etc/postfix/local-host-names
- example.admin@example.com and info@example.com are both present in /etc/postfix/virtusertable and point to example.admin
- example.com is listed in /etc/postfix/local-host-names

Any help would be greatly appreciated!

What's in your mail log when this happens?

Here's /var/log/mail (snippet):
test@example.com is an alias I've set up for admin@example.com.

Thanks

What's in /etc/postfix/main.cf (please strip out the comments), /etc/postfix/virtusertable, and /etc/postfix/local-host-names?

/etc/postfix/main.cf

/etc/postfix/local-host-names
/etc/postfix/virtusertable (snippet only - I don't want the users of twenty sites plastered all over the forums)

Ok, and now I need to know the real email addresses instead of test@example.com and admin@example.com.

In this case, so I wasn't cluttering anyone else's mailbox, I set up the username testing, which has test@markanthonymedia.com as an alias, just so I could confirm the behaviour with a fresh email. (The original user who noticed the problem is on another site I host.) The user testing then forwards to administrator@markanthonymedia.com.

The original notice was when a PHP script mailed to an alias - I got the undeliverable message error, since wwwrun's email forwards to me. I also tried sending to info@markanthonymedia.com, with the same result (info is an alias for markanthony).

What's in test@markanthonymedia.com .procmailrc file (in his homedir)?

Please run
to get rid of the inet_protocols warning in your mail log.

Thanks, I was wondering how to get that error out.

The user is testing, not test - perhaps I should've made it testuser or something. The email test@markanthonymedia.com is just an alias of testing@markanthonymedia.com.

The .procmailrc for testing, however, is as follows:

MAILDIR=$HOME/Maildir/
DEFAULT=$MAILDIR
ORGMAIL=$MAILDIR

INCLUDERC=/srv/www/web1/user/testing/.mailsize.rc
## INCLUDERC=/srv/www/web1/user/testing/.quota.rc
## INCLUDERC=/srv/www/web1/user/testing/.antivirus.rc
## INCLUDERC=/srv/www/web1/user/testing/.local-rules.rc
## INCLUDERC=/srv/www/web1/user/testing/.html-trap.rc
## INCLUDERC=/srv/www/web1/user/testing/.spamassassin.rc
## INCLUDERC=/srv/www/web1/user/testing/.autoresponder.rc

And what's in the .forward file (in the same directory)?
