In my ISPConfig 3 installation, I compared my log with the output from Perfect server guide. I realize that this line is missing : Configuring SASL Configuring PAM Is it important? I check it with grep and found cyrus-sasl and pam, so I conclude it was installed on my server. Now the ISPConfig 3 server is running ok. But sometimes the POP3 and IMAP server suddenly become offline. Is it because the problem above? When it happens, the saslauthd service stopped by itself, but the dovecot and postfix still running. Usually I abort postfix , then restart the dovecot, postfix and saslauthd. After that the server is OK again. Just for info, I use a VPS, so I don't know for sure what is installed in the OS in the first place. For example, cron is not installed in the first place.
This is probably because I use an older ISPConfig 3 version in the tutorial. Shouldn't be a problem. Any errors in your mail log?
error mail log I did some change in time and date of my server with ntp. Is this maybe the cause? It said : dovecot : Fatal: Time just move backwards by 25177 seconds...... so I'll just kill myself now. Rather funny, it commited suicide After that, the log repeatedly says these 4 lines: postfix/smtpd : warning: SASL: Connect to private/auth failed: Connection refused postfix/smtpd : fatal: no SASL authentication mechanisms postfix/master : warning: process /usr/libexec/postfix/smtpd pid 5522 exit status 1 postfix/master : warning: /usr/libexec/postfix/smtpd: bad command startup -- throttling Now after I restarted everything, and everything runs well, the log repeatedly says these 5 lines: dovecot: pop3-login: Disconnected (no auth attempts): rip=127.0.0.1, lip=127.0.0.1, secured dovecot: imap-login: Disconnected (no auth attempts): rip=127.0.0.1, lip=127.0.0.1, secured postfix/smtpd[26885]: connect from localhost.localdomain[127.0.0.1] postfix/smtpd[26885]: lost connection after CONNECT from localhost.localdomain[127.0.0.1] postfix/smtpd[26885]: disconnect from localhost.localdomain[127.0.0.1] How about the last log? Is it normal or there's an error? Thanks for the reply
