Thanks for sharing you solution, hopefully it will help others.

It’s a good point about gluing the tutorials together, usually you are not just setting up a standalone IMAP/POP server, you’ll also need a SMTP server and possibly spam filtering. I think it would be a good idea to create complete mail server setup tutorials.

…and a final word

on the internet you can find quite a numer of tuts/howto’s about setting-up a maileserver of some sort using any number and combination of an array of tools that need to be glued togerher. this glueing can become quite complex and require some serious concentration, reading etc.

I just finished a mailsetup using 3 artikels from this site plus a dozen others for several detaills. This roughly took me a day or so to finish.

But it took another 3 days before it was working properly, because all the time i was overlooking something very crucial, but super-obvious…

And not even 1 of all these sites/blogs that i used as a guide makes any mention of it. It is asumed taken care of and it’s another-/offtopic etc..

so to spare others the kind of the frustration i experienced last few days:
if you find your setup is not acting as it should, and although still learing, you think your config is right.. also make sure to CHECK YOUR DNS RECORDS

one of mine was changed without me knowing it.. i guess in my sub-consious just asumed they were alright.. simply never thought to double-check those

thanks for the article, and your support,

small additional question;
the virtual domains mappings file from this page:
http://www.debiantutorials.net/installing-postfix-with-mysql-backend-and-sasl-for-smtp-authentication/

… defines “select_field = ‘virtual’” , while the table-definition only defines 1 table ‘domain’.

is that an error? or does this work because “right-hand content does not matter” virtual(5)?

hi aip, thanks for responding.
actually that’s what i’m doing (log-watching). but on this issue they don’t report anything. and strange enough, watching raw traffic using tcpdump i don’t even see any traffic. ..must be doing something else wrong..

Hello arri

If you are using the MySql backend you don’t need the /etc/postfix/virtual file because the users are stored in a MySql database. Can you check the /etc/log/mail.log file, it may contain some additional information.

Hi,

i glued together 3 of the articles on this site, in order to create a mailsystem with postfix, dovecot(imaps), sasl (cyrus), dspam and clamav.

i ‘seems’ everything is working, except that any mail sent TO this server will consistently gets bounced with error code 550 550 5.1.1
Recipient address rejected: User unknown in virtual alias table (state 14).

i already tried creating a /etc/postfix/virtual table and add the hash to virtual_alias_maps, but that’s not the solution…
any idea where i should look?

btw, great howto’s, especially if this problem turns out to be my own stupid fault.;)
