[nos-bbs] POP3 from GMAIL

I have a hack solution...   If the popclient destination mailbox is
GMAIL (or something equally triggering) then run a tweak to calculate
the destination mailbox from the Mail-to string of:
BBSHOSTNAME+MAILBOX-NAME at gmail.com.   It'll be easy to pull out the
string 'MAILBOXNAME' and simply save the message there.   Still not as
clean and it bypasses the rewrite and alias functionality but it
should work...
