New Python 3 port of TMDA, plus a simple CGI wrapper for it

[Jonathan K. <ji...@ka...>]

Well, I wish i'd bothered to check recent messages on this mailing list 
before spending about 12 hours yesterday porting version 1.1.2 of TMDA 
to Python 3. It would have saved me a lot of time.

I've uploaded my port to https://github.com/jikamens/tmda . It's 
certainly not fully tested since I only use a subset of TMDA's 
functionality, but it's working at least for what I use it for. I 
welcome additional patches.

I've also included a simple CGI script written in Perl that you can use 
as a front-end to tmda-pending to allow you to whitelist and blacklist 
senders and delete messages through a web server running on the same 
machine as TMDA. It's in contrib/simple-tmda.cgi 
<https://github.com/jikamens/tmda/blob/main/contrib/simple-tmda.cgi>.

Feedback / bug reports / pull requests are welcome, of course.

Regards,

Jonathan Kamens
