Slow inbound email and the fix

Filed under: EBS,TMG — WITS-SR @ 7:06 am

We had a problem with inbound mail taking up to 3 minutes to enter our inbox, even though we saw TMG logs getting the email within 5 seconds of it being sent.

If you have the edge Anti-spam configured and enabled, specifically “IP Block List Providers” & “Sender ID” you might get this latency.

We fixed it by creating an access rule that says:

From: Localhost

To: Internet

Protocol: DNS [not dns server]

Action: Allow

Emails are flowing in with no issues after this change.
