[Mailman-Users] different attachment for different email

[Donatas]

Hello,

I need to sent messages su 150-300 emails. But I need to attach a different
attatchment for a different email. The attatchments differ, it can be any
file with any extention (e.g. doc, xls, txt, jpg).

I imagine, that attatchments should be attatched from some kind of foldels
for eatch email.

aaa at bbbb.com takes attatchment from "hehe" folder
xxx. at asdasdasd.net takes attatchments from "xoxo" folder
and so on...

Any ideas, working solutions?
