Since his mail was in response to one of your misconfigured emails, it
isn't libelous. Sorry. I suppose you could retain a lawyer if you're
serious about making a libel claim.
Say, is your broken threading an inadvertant misconfiguration, or did
you break it on purpose?

He's got as much right to speak here as you, I imagine, this being an
open forum and all.
However, since you brought it up, who are _you_? What's your
experience? Where's your resume and references? Have you audited all
this code you've written for race conditions, deadlocks, and the like?
IOW, why should I download your software which you blithely claim
solves all spam problems until the end of time? If I had no opinion
regarding CR, I still would think twice about downloading yuour
software. Your conversations here do not encourage me to believe that
you would handle bug reports in a fashion pleasing to me. ("The
software does not work in this situation." "Yes it does! You do not
understand the software." "...")
