SMTP and AVAST 2015

I have been using Avast for years with my own SMTP server. Now all of a sudden I am being put on block list cause when Avast is active the EHLO is localhost.localdomain instead of what is should be. If I disable avast my EHLO is correct, where is the settings to correct this problem?

Update: I have found it is the antispam module causing it. Still working on the solution.

So Far the only solution is to disable antispam. Unless someone has another fix, this is what I have had to do, thankfully I don’t need this module.
