Dr. Web killed my email

[thedust2010]

I had to disable Dr. Web today in order to get email services running properly. After adding a few new users to utilize Dr. Web, the service froze up and needed a restart so I did and now every email I send out I get an immediate return:

554 mail server permanently rejected message (#5.3.0)

I would like to repair Dr. Web if it's possible, but if it's not reccomended, then what other options do you think I have? Anyone else experience this issue?
