Yeah, I get it.

Anything that I want to run post-ssh-add, though, I do through a
little shell script (started in its own miniature xterm from what's
now in my VTWM_Profile) which runs ssh-add, then executes everything
that requires the passphrase to actually be entered. (This is why,
as you may have noticed if you've ever watched me log in somewhere,
I get a bunch of xterms, then enter my passphrase, then get a few
more xterms on other machines.)

Not saying my way is inherently better, but if I were going to be
using POP/IMAP for anything (which I never would for unrelated
reaons... I much prefer forwarding, I don't receive any email
through lame NT boxes, etcetera), I would put my fetchmail call
there.

Heck, if you don't want the xterm-ized ssh-add routine, I bet you
could just run ssh-ask-pass && ( fetchmail ; sshes ) as a child of
your window manager and be happy.

Hope that (actually, this time) helps...
