Topic: imap connections fail until postfix is restarted
==== Required information ====
- iRedMail version: mail_version = 0.8.6
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Linux/BSD distribution name and version: CentOS 6.5
- Related log if you're reporting an issue: Unsure of which log to give
====
My mail server is at times refusing imap connections and I am unable to send mail. This is occurring every so often. Once it occurred in as little as 5 minutes. All I'm doing right now is restarting postfix to get it to send mail again. There is nothing obvious in any log that I have checked (maillog, messages, dovecot, mailq) that would be the cause of this issue. I'm not sure which one would be useful so if I should include some more just ask.
Does anyone know what might be causing this or at the very least what I should be checking?
Any guidance at all would be greatly appreciated.
Edit:
I've attached the following except from the log just in case it will be of any help. This is the output of the following command.
