Why are you using POP3 when scanning smtp/s?

What does the xg logviewer -> mail show for the failed attempts and also what d\oes the exchange server show for the same messages?

Hi,

I would suggest you create a support case. There might a be setting in CLI that enables you to increase the limit, possibly in the default mail DoS settings.

Hi osama,

I would suggest you contact your reseller/partner for assistance in creating case.

At the top righthand of the forum pages there is a support portal, you could also try that.

Open the ticket and one of the sophos forum support staff will probably ask you the number.
