Hi all, I'm not too familiar with postfix but our server seems to stop sending emails usually only on the weekends. The rest of the week it's fine but once it gets to about Saturday/Sunday morning it gets stuck. I've come in usually on Monday and type "mailq" only to find hundreds if not thousand or so emails stuck in the incoming queue. I have to restart the postfix service for all the emails to get sent.
I was hoping someone a little more experienced than me can point me in the right direction and explain what's going on as I'm not that familiar with it yet. I'm sure I'm not the first to have this issue and I've searched online but have found nothing specific that could be causing this. This is what "cat /var/log/maillog | grep warning" shows: Dec 11 05:09:19 batch-ca4-02 postfix/cleanup[31691]: warning: timeout on cleanup socket while reading input attribute name Dec 11 05:31:27 batch-ca4-02 postfix/cleanup[31691]: warning: 8A2993E3003B: read timeout on cleanup socket Here is my postconf -n: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 html_directory = no in_flow_delay = 10s inet_interfaces = localhost mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost mydomain = usaepay.com myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES relayhost = 192.168.x.x sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop unknown_local_recipient_reject_code = 550 Can anyone please help??
