[Dovecot] Combination of default domain and username character translation problem in POP3 server configuration
by Vico 19 Nov '09

19 Nov '09

Hello, I have a mail server running vm-pop3 and I am migrating it to Dovecot. I have a problem configuring Dovecot as a POP3 server only (I'm not interested in IMAP for now). I have two types of domains: one principal domain, whose users don't include the domain in the login process; and secondary domains, whose users include the domain part with the ! separator, instead of @ (i.e. prueba!mysecondarydomain.es). Because of that, I have set the following options in the configuration file: auth_default_realm = myprincipaldomain.es auth_username_translation = !@ The combination of these two parameters produces the following effect when I login with an user of a secondary domain (I have no problem with principal domain authentication): +OK Bienvenido al servidor de correo. user prueba!mysecondarydomain.es +OK pass prueba. -ERR Authentication failed. quit +OK Logging out This is the resulting log: Nov 19 09:58:51 prueba dovecot: auth(default): new auth connection: pid=21953 Nov 19 09:59:04 prueba dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=192.168.1.84 rip=192.168.17.13 resp=AHBydWViYSF0b2JhcnJhLmVzAHBydWViYS4= Nov 19 09:59:04 prueba dovecot: auth(default): passwd-file(prueba@mysecondarydomain.es@myprincipaldomain.es,192.168.17. 13): no passwd file: /etc/virtual/mysecondarydomain.es(a)myprincipaldomain.es/passwd Nov 19 09:59:05 prueba dovecot: auth(default): client out: FAIL 1 user=prueba@mysecondarydomain.es@myprincipaldomain.es So, I think the problem is Dovecot tests if the default domain is needed before the character translation is done, so the character ! is not detected as a domain separator, so the default domain is always appended. The question is how I could resolve this problem. I need these two operations to be done because there is a lot of users already working with this configuration. Thank you in advance.

[Dovecot] unix_listener with user/group setting
by Pascal Volk 19 Nov '09

19 Nov '09

Hi Timo, are there any plans for configurable user/group settings for a Unix socket? I had tried this configuration: service auth { user = nobody unix_listener /var/spool/postfix/private/auth { mode = 0600 user = postfix group = postfix } } The mode of the socket was fine but it was owned by nobody.

[Dovecot] Maildirs++ on ext4
by Rodolfo Gonzalez Gonzalez 18 Nov '09

18 Nov '09

Hi, happy after migrating from Courier to Dovecot without major issues, and saving 3 Gb of RAM after the migration, now I'm going to move everything to a 5 Tb RAID6 array. There's another thread on SATA and cluster fs, but for now I'm looking for the best filesystem in your experience. Currently I use Reiser, but I'd like to know if someone has worked with ext4 and Dovecot's maildir++. Thanks. P.S. I have UPS and generator, but my RAID card doesn't have backup battery.
