i already have quite large dovecot installation with multiple domains but with users handled via unix passwd.
Domain name mapping in both directions is done by sendmail, and mail delivery by procmail to Maildir format - one account per user. this accounts are often used for more than mail.
So for example john smith have email john@foo.pl and unix username foo-john.
His imap client and smtp client is configured to use login foo-john and email address john@foo.pl
Everything works flawlessly.
But i will have few new users that insist of being able to login as someone@somewhere.pl
Can i have something similar to sendmail method in dovecot - an alias table like
someone@somewhere.pl some-unix-account
For this few users and have everything like it is now?
