This parameter doesn't appear to be set in the "postconf -n" output show showed, or in your master.cf. The default timeout is 300s. This leaves us with a few choices: - you have multiple postfix instances, and you're showing us settings from the wrong instance. - some other software or device is interfering with the smtp protocol. - some idiot has compiled postfix with non-standard default values that don't show up in postconf -n output. I don't think I can offer any further help here. -- Noel Jones
