I have a Ubuntu server 12.04 hosted in another country. I have installed Postfix and Dovecot for my mail server. I can receive mail from services like yahoo and google. I can view my server inbox using Sylpheed with IMAP or POP3. I can send mail anywhere (tested with yahoo, google , hotmail). If I: telnet localhost 25 from the server I can send mail. But if I: telnet server_domain 25 from home I can't send mail (relay acces denied). I know this happens because my home ip is not in the mynetworks parameter in postfix, but because I have a dynamic ip I can't set it in the config file. So I want to connect with SASL authentication to be able to send mail. Following the Dovecot documentation on Postfix/Dovecot SASL I configured both Dovecot and Postfix for SASL but when I telnet I don't receive this message: 250-AUTH PLAIN LOGIN. I know my dovecot configuration is not set right because I get errors like this when starting up dovecot: "doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:10: userdb passwd {} has been replaced by userdb { driver=passwd } " If I put this: auth default { mechanisms = plain login passdb pam { } userdb passwd { } socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix }}} In the dovecot.conf file (the syntax is diferent in my version of dovecot (2.0.19) than all the guides I found on google) Can you translate the configuration above in the new dovecot syntax?
Solved it The configuration for dovecot is in 2 places /etc/dovecot/dovecot.conf and in /etc/dovecot/conf.d. I found the necessary configuration parameters commented in: /etc/dovecot/conf.d/10-master.conf
