Alias mappings

[rusty]

Hi.

My virtual users are working fine. mail goes to the right mailbox. However, mail that needs to be forwarded to another user on the same domain, instead goes in that user's mailbox. (ie. joe@example.com goto mike@example.com lands in Joe's mailbox.) Postfix is referring to the correct db table (if I alter the name in mysql, the mail bounces). Somehow, postfix ignores the destination address in the goto field.

I'm using postfix, dovecot, postfixadmin, amavis

Any help would be greatly appreciated.

Thanks,

Eric

Any errors in your mail log? What's in your main.cf?

[rusty]

Falko,

You're the best! Thanks for replying. First, I pasted contents of the log file. I don't see any errors. Two emails were sent at the same time, one to a virtual mailbox, and another to an alias that forwards to a virutal mailbox of another user. I can't see any difference. For the alias email, the message ends up in the recipient's mailbox instead of forwarding to another user's mailbox. Do I need to delete the recipient's mailbox now that I want it to forward to another user. To help make it clear, one employee quit, so their mail needs to forward to another employee's mailbox.

After the maillog entries, I pasted the contents of main.cf.

What's in /etc/postfix/mysql_virtual_alias_maps.cf?

[rusty]

See below for the file requested.

My mysql database was setup by the script that comes with postfixadmin.

As mentioned in my initial post, if I alter the address field in the alias table, delivery fails completely (so it is sucessfully accessing the mysql db).

I have also used this file with the last line commented and all the others uncommented:
mysql_virtual_alias_maps.cf
*********
user = myuser
password = mypassword
hosts = 127.0.0.1
dbname = mail
#table = alias
#select_field = goto
#where_field = address
#additional_conditions = and active = '1'
query = SELECT goto FROM alias WHERE address='%s' AND active = '1'

[falko]

Looks good.
What's in your alias table?
SELECT * FROM alias;

[rusty]

mysql> SELECT * FROM alias;
+-------------------------------+-------------------------------+--------------------+---------------------+---------------------+--------+
| address | goto | domain | created | modified | active |
+-------------------------------+-------------------------------+--------------------+---------------------+---------------------+--------+

Does this answer your question, or do you need to see the actual data?

[falko]

If the table is empty, then it's clear why it's not working, but if the forward is in there, then I don't know what's wrong... :confused:

[rusty]

Yes, the table has data in it. I have examined it and it looks correct. Thanks for trying.

Could you answer one question? Does it look like the Dovecot service is involved in delivery to the mailbox? Here is an entry in the log:

Jan 29 15:56:06 mail postfix/pipe[28583]: 4AD4C57805F: to=<mtb@domain.net>, relay=dovecot, delay=0.03, delays=0.01/0.01/0/0.02, dsn=2.0.0, status=sent (delivered via dovecot service)

Should I look there for the problem? I've been assuming Postfix is controlling 100% of the delivery.

That's strange. Normally the delivery is done by Postfix, and Dovecot is used only for fetching mails from the server.

That's strange. Normally the delivery is done by Postfix, and Dovecot is used only for fetching mails from the server.

This is being delivered using dovecots LDA mechanisim.

http://wiki.dovecot.org/LDA/Postfix

[rusty]

Yes, topdog is right.

The dovecot.org list told me dovecot ignores alias mapping. Since the postmap command showed the alias address was properly output, I looked at where in between postfix and dovecot the alias mapping was being lost. I did some research and I found that when using amavis, alias mapping was applied after it returned the message to postfix.

So I focused my attention on the master.cf in the amavis section. That's when I found a stray # found it's way into the line that starts with -o receive_override_options=

Stupid mistakes can be the hardest to figure out!
