Hi altogether,
I am switching from dbmail 2.2 to dovecot 2.1.7, and I was able to do a successful transition of IMAP. But I had a very hard time with receiving mail, and in the end -- after loads of reading and debugging -- I broke down and failed. This is why I am asking you for your kind help.
I only have virtual users and have set
mail_uid = dovemail mail_gid = dovemail
For authentication, I simply use (for now) a flat file:
passdb { driver = passwd-file args = scheme=PLAIN username_format=%u /etc/dovecot/mypasswd.file }
# cat /etc/dovecot/mypasswd.file user1:{PLAIN}userpw1 user2:{PLAIN}userpw2 user3:{PLAIN}userpw3
And everything works fine with IMAP. I am completely domain-agnostic here. But I was not able to use this fine setup to receive mails with my postfix. I tried about 13 different configurations, some with considerable changes dovecot-config, the passwd-file or postfix, but I could not find a single variant working.
In this situation, I would be very happy if somebody could give me a hint, which would be the prudent way to configure dovecot, LDA/LMTP and postfix based on the setup above.
Thank you very much in advance, and have a great time,
Matthias Hofer
