Thunderbird problem after installing 4.2.64.12

I have been having problems sending email since installing ESS 4.2.64.12 Friday. When I forward or reply to an email, it goes into my ESET Antispam folder without it being sent. How do I fix this so my emails get to their destination?

 

Please have a look at your email "blacklist" settings in ESS. Looks like you somehow have managed to put your own email address onto the blacklist.

In advanced mode goto Setup --> Antispam protection --> User's Blacklist

 

My email address is not listed in my blacklist, just checked. The only offenders are the two that I have blacklisted prior. Email still not arriving at inbox's when forwarding or replying.
