well, i dont auth users in mysql via dovecot ! im authorising users in vpopmail, and vpopmail stores logs in mysql, and the database isnt going away...

so its something else, here's my dovecot.conf, stripped of comments :

protocols = imap pop3 ssl_disable = yes disable_plaintext_auth = no log_path = /var/log/dovecot.log info_log_path = /var/log/dovecot.log log_timestamp = "%b %d %H:%M:%S " login_user = dovecot login_process_size = 64 login_processes_count = 1 login_max_processes_count = 8 login_max_logging_users = 16 login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c login_log_format = %$: %s first_valid_uid = 50 mail_debug = yes default_mail_env = maildir:%h/.maildir mail_log_prefix = "%Us(%u): " protocol imap { } protocol pop3 { } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb vpopmail { args = } userdb vpopmail { } user = root }

so, i use vpopmail to auth my users,but after upgrading from dovecot-0.99.14-r1 to dovecot-1.0_alpha5 and tweaking dovecot.conf i get this in the log :

dovecot: Dec 15 12:12:11 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=81.xx.xx.xx rip=81.xx.xx.xx resp= dovecot: Dec 15 12:12:11 Info: auth(default): client out: CONT 1 dovecot: Dec 15 12:12:11 Info: auth(default): client in: CONT 1 AGRhbmlAbGludXhzb2x1dGlvbnMfgucm8AcG9jcG9j dovecot: Dec 15 12:12:11 Error: auth(default): vmysql: sql error[3]: MySQL server has gone away

--^ Isn't it caused by this?

...

dovecot: Dec 15 12:12:11 Info: auth(default): vpopmail(dani@domain.com,81.xx.xx.xx): unknown user dovecot: Dec 15 12:12:12 Info: auth(default): client out: FAIL 1 user=dani@domain.com dovecot: Dec 15 12:12:12 Info: auth(default): client in: AUTH 2 PLAIN service=POP3 lip=81.xx.xx.xx rip=81.xx.xx.xx resp=AGRhbmlAbGludXhzb2x1dGlvbnMfgucm8AcG9jcG9j dovecot: Dec 15 12:12:12 Error: auth(default): vmysql: sql error[3]: MySQL server has gone away dovecot: Dec 15 12:12:12 Info: auth(default): vpopmail(dani@domain.com,81.xx.xx.xx): unknown user dovecot: Dec 15 12:12:14 Info: auth(default): client out: FAIL 2 user=dani@domain.com

so no one can login no more via pop3/vpopmail ..

anyone any ideas?

thx.
