Hello all,

I am having trouble with a virtual alias that is being run through a
Postfix (2.2.12) installation that uses MySQL for virtual domain
mappings. I get an error in my maillog that says the alias is an
unknown user after I send mail to that alias.

We'll assume virtual domain of example.com, and the alias is
"alias(a)example.com" and the destination is "realmail(a)example.com"

I have my main.cf as follows:

virtual_alias_maps = mysql:/etc/postfix/sql/virtual_alias_maps.cf

When I run a

#postmap -q "alias(a)example.com" mysql:/etc/postfix/sql/
virtual_alias_maps.cf

I get

realmail(a)example.com

So the mappings seem to be working correctly.

But when I

#mail alias(a)example.com

and send mail on to the alias(a)example.com address, this shows up in my
maillog:

Apr 29 15:26:03 example postfix/virtual[17937]: C771D11CC61B:
to=<alias(a)example.com>, relay=virtual, delay=1, status=bounced
(unknown user: "alias(a)example.com")

And then it is, obviously, lost :(

I can send mail directly to realmail(a)example.com without any issues so
I know that example.com is configured correctly (or at least,
correctly enough?)

Anyone have any ideas I could try to get aliases working?

Thanks,
Wesley

This is virtual_alias_maps, the thing which REWRITES addresses

THIS is the virtual delivery agent at work, which uses
virtual_MAILBOX_maps

Sounds great - makes sense.

Thanks!

I've been having this same issue, and I am a bit lost in your reply.

How would one make it so the alias file works? rather then having a
box for each address.

The error message is not related to that particular setting. You'll
need to take a closer look at the Virtual Address ReadMe to troubleshoot
your set up. If you grep your main.cf file for "virtual" then you'll
either find virtual *mailbox* settings that conflict with your
virtual *alias* settings or that the ultimate destination for the
aliased address is not configured properly in virtual mailboxes.
