Mail delay at MailScanner

[Eli Wapniarski]

Looking at MailScanner's configuration there is an option there

Max Normal Queue Size

The speed of your mail delivery. If you could check how many messages are sitting in your queue then maybe we can get to the bottom of it. If I understand the explanation correctly and the delay is not being caused by misconfigured greylisting then I would think you've got alot of ping ponging.

This can be dealt with, but it would take some work.
