Hello, I use Thunderbird extensively, it's always in my systray in Linux Mint or Windows. I chose SpamAssassin as the hidden program that decides what is spam and what isn't. I picked SpamAssassin because it seemed aggressive, but I'm not sure if it's the best one, it's hard to find info about this at all. There's a series of similar looking spam messages making it into my gmail account which I have linked to t-bird that usually end up in the Spam folder, but a few didn't recently. I'll take advice on any of these. For some reason, some of them look old just by their name, PopFile, DSPAM...but that's my own non-scientific triage. Anyone who's in the know about this, at Mozilla or otherwise, I'll take your advice. Thanks!
