After reading lot of things about this problem on iredmail forums, i can't find a solution : The postfix queue is very slow to be processed on my server.
The problem focuses on local delivery, sometime it can take up to 1hour for a message to be delivered to a user whereas there is only 40/50 messages in the postfix queue.
When i look at CPU usage, it turn around 99% of idle... but sometime, amavis wake up for few seconds, then nothings during 30 sec or 1min.
The machine on which is installed iredmail is largely oversized for our use.
I don't understand what the hell postfix is waiting for to deliver messages.
Please help me to debug this.
