Hi all, first post regretfully...
I am also getting this error. All of my google accounts have SSL/TLS disabled, and yet for some reason it shows it as going forward as having it. I also have google's imap, and pop, and smtp in the Mail Shield -> Advanced -> SSL settings.
I am using Mail 5.2 and Lion 10.7.3... 16GB ram (soon to be 32GB), and half a Petabyte of HD space. 8TB on my computer alone. Yes I'm a geek...
I am using Avast Beta 7.0 (36454)... so just reporting in the bug...
