SERVER-MAIL Dovecot Submission-Login Service NULL Pointer Dereference

Hi,
description is here -> http://services.netscreen.com/documentation/signatures/SMTP%3ADOS%3ADOVECOT-NULL.html

I've got same messages when my fileserver sends me an email, and email was configured with no authentication,
when i filled it up, there was no error messages at sophos side

Cheers!

Seems like a false positive.

Can you give us the IPS ID? 

Hi,

i've got the same issue.

The IPS ID is : 1190508052

It blocked access to the domain name of my mail server.
I solved the problem by allowing the domain name in Web, Exception, add, URL : ^([A-Za-z0-9.-]*\.)?mydomainname\.fr/

I have access to my mail server again but the logs are still present...

Would suggest two steps.

First report this issue to sophos support to get the false positive removed from IPS pattern.

Second, exclude this from your pattern: https://community.sophos.com/kb/en-us/132879
