1. In src/Makefile, add pop to SUBDIR, so it looks something like:
SUBDIR= tools uip submit deliver local phone pobox bboards pop smtp uucp
2. In mmdftailor, add these lines
MTBL pop, file="pop", show="POP service"
MDMN POP, show="POP Psuedo-domain", table="POP"
MCHN pop, show="POP Delivery", que=pop, tbl=pop,
pgm=pop, mod=reg, ap=822, host="pop"
3. Create the table for the POP channel, one line:
pop: pop
4. Run dbmbuild
5. In your mmdf.start file, either add the pop channel to an
existing background deliver, or give it one of its own:
deliver -b -cpop &
