    postfix has NOTHING to do with your POP3 server. If some postfix
overload is braking your POP3 daemon, then you're probably running out
of linux resources and thus need some tweaking (more hardware or
software tweaking) on your whole OS, not only postfix.

    500 requests on the queue are not that much. On servers with lots of
users, this would be considered completly normal. Even much more than
500 would be normal depending on the number of users. But for a few
users system, maybe that's too much.

    First of all .... you need to tell us WHY your messages are stucked
on the queue. Are they there because postfix is slowly-processing them
or they are there because they are being slowly-delivered to/delayed by
their destination servers ??? We can't figure that out, you need to tell
us this.

    if postfix is processing the messages but they can't be delivered to
the internet, for example, because of a slow internet connection, then
there's NOTHING postfix could do for that.

    Give us some more informations and maybe we can help you :)
