If you just want a mail client script to run under AOLserver, that is
actually quite easy. In fact, if you search the aolserver mailing
archives, you will find some POP routines posted. I think the post
dates way back to 1999. I have them in a tar file somewhere, so
if someone else doesn't find them. I'll dig them up this weekend.
There is at least one TCL imap package, so one could just take
the imap routines from that, and fold them into an aolserver
library...and write a couple scripts to grab and receive mail. the
tricky parts about each of these is going to be properly displaying
MIME extensions...but that type of thing is mostly well defined
and will just require some programming.
