[Dovecot] Dovecot 2.2.0 Compilation Error
by Jacques Distler 14 Apr '13

14 Apr '13

On MacOSX 10.6, I get: ld: duplicate symbol _cmd_batch in dsync/.libs/libdsync.a(doveadm-dsync.o) and doveadm-mail-batch.o for architecture x86_64 collect2: ld returned 1 exit status make[4]: *** [doveadm] Error 1 when compiling Dovecot 2.2.0. By contrast, 2.1.16 compiled (and runs) just fine. I'm surprised that this hasn't cropped up elsewhere.

[Dovecot] How to manually generate a password hash
by David Murphy 14 Apr '13

14 Apr '13

Hi folks. I've recently set up a Postfix 2.9.6/Dovecot 2.0.19 IMAPS/SMTPS setup on Ubuntu 12.04.2 (Mysql backend). I'm new to all this, so I apologize if this is fairly basic. I've attempted to the best of my ability to search for an answer, but no luck so far. What I'm trying to do is generate a password hash that I can inject directly into my Mysql database (disaster recovery sort of situation). Towards that goal, I'm trying to use 'doveadm pw' to generate a hash that matches a known password in my database. Unfortunately, I'm coming up empty. My default_pass_scheme in dovecot-sql.conf is set to MD5-CRYPT, and the passwords in the database have no scheme prefixes. I'm attempting to generate a hash with: sudo doveadm pw -s 'MD5-CRYPT' but the hash generated does not match the user's password hash in the database, which is known to be a good password. I'm able to log into this account successfully in both Roundcube and a remote IMAP client. I've also tried using the -p flag and including the password in the command, and that doesn't do it either, though it oddly gives a different response than using the prompt. (What causes this? Newlines?) So... what am I missing? If the hash was salted, it would seem the hashes in the database would be longer than the ones generated at the command line, but that isn't the case. I'm out of ideas. Any guidance appreciated. -Dave

[Dovecot] LMTP Setup/Design Help Request
by Matthias Hofer 13 Apr '13

13 Apr '13

Hi again, Thank you for your first hints. I have now set up a dedicated test instance of postfix and dovecot to be able to recreate the problems in detail. Even after using your inputs, they do not seem to work with my setup I already mentioned above. I get errors like postfix/lmtp[10994]: C2DF4C000DF: to=<user1(a)mydomain.org>, relay=mail.mydomain.org[private/dovecot-lmtp], delay=0.1, delays=0.05/0/0/0.04, dsn=5.1.1, status=bounced (host mail.mydomain.org[private/dovecot-lmtp] said: 550 5.1.1 <user1(a)mydomain.org> User doesn't exist: user1(a)mydomain.org (in reply to RCPT TO command)) As stated before, my setup is as follows: > 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. I do not know how to strip the domain when the username is handed over from postfix to dovecot, and what would be the sane solution. I hope, you can give me a hint to that. Thank you, again, and greetings, Matthias Hofer

I did not think about that, but this solved this issue :D Thank you a lot. And I was now able to solve also my further issues. So I am prepared to try again to switch :) Have great day!
