Hi there,
I've written the following example handler for Mailman but have a bug
that I can't for the life of me understand why it's happening... It's
based on Personalize.py (yes, I'm aware it's deprecated, but it works
for me. :-))
Basically. The email gets encrypted correctly for the first person (and
sent to them), but the second person gets person one's mail encrypted!!
Basically "valu"e doesn't get reset back to the actual unencrypted email
contents (msg).
I'm sure I'm missing something stupid in my loop (to do the multi-part
stuff). If someone spots it I'ld really appreciate a mail.
Thanks in advance.
