Hi postfix users, I wonder if there is anyone who experienced the issue like me and what is the cause/solution for it.
I need to debug delivery problems from certain IP. For that I add this IP to main.cf debug_peer_list and restart postfix. All looks fine, connections from that IP produces a verbose logs, however there is a gap of 30s in the logs. I have quite a large number of ldap lookup tables configured. Logs show that postfix enters a stage of >>> CHECKING RECIPIENT MAPS <<<, does a several ldap lookup tables checks and then silent for 30s, then I see a QUIT command comming from sender IP (a timeout probably). So most interesting information is just not shown. here is the snip of the logs I see: ..... 2015-06-10T15:29:32.261120+02:00 mx05 postfix/smtpd[28480]: >>> CHECKING RECIPIENT MAPS <<< ..... 2015-06-10T15:29:32.267755+02:00 mx05 postfix/smtpd[28480]: dict_ldap_get_values[1]: Search found 1 match(es) 2015-06-10T15:29:32.267787+02:00 mx05 postfix/smtpd[28480]: dict_ldap_get_values[1]: search returned 24 value(s) for requested result attribute associateddomain 2015-06-10T15:29:32.267793+02:00 mx05 postfix/smtpd[28480]: dict_ldap_get_values[1]: Leaving dict_ldap_get_values 2015-06-10T15:29:32.267798+02:00 mx05 postfix/smtpd[28480]: dict_ldap_lookup: Search returned <the list of mydestinations> 2015-06-10T15:30:02.978509+02:00 mx05 postfix/smtpd[28480]: < sender[IP]: QUIT 2015-06-10T15:30:02.978576+02:00 mx05 postfix/smtpd[28480]: > sender[IP]: 221 2.0.0 Bye It looks to me that there is a limit of data which can be logged, therefore it is just omited. BTW - logs go to remove rsyslog server. Postfix version 2.6.6 Any thoughts? Regards, Liutauras
