Gateway slow at receiving email

[Rick BRaakman]

Good Afternoon,

When someone mails a target domain in our mail gateway it is received late.

For example:

info@example.com send a mail to info@abcd.com (both added in gateway) at 12:16

It takes half a hour until Promox receives this email.
When I look in the tracking center de mail is received at 12:43 and processed.

Its a virtual environment with plenty of resources. Does anybody got a idea how to fix this?

Do you use greylisting?

 

[Rick BRaakman]

Yes we have greylisting enabled on our gateway.
But if we turn it off we receive alot of spam.....

Just check the emails via the "Message Tracking Center", so you should see in the logs why there is such an delay.
