## Additional -D flags for movemail (add to MOVE_FLAGS if desired):
## MAIL_USE_POP		Support mail retrieval from a POP mailbox.
## MAIL_USE_MMDF		Support MMDF mailboxes.
## MAIL_USE_FLOCK	Use flock for file locking (see the comments
##			about locking in movemail.c)
## MAIL_UNLINK_SPOOL	Unlink the user spool mailbox after reading
##			it (instead of just emptying it).
## KERBEROS		Support Kerberized POP.
## KRB5			Support Kerberos Version 5 pop instead of
##			Version 4 (define this in addition to
##			KERBEROS).
## HESIOD		Support Hesiod lookups of user mailboxes.
## MAILHOST		A string, the host name of the default POP
##			mail host for the site.

## Additional libraries for movemail:
## For KERBEROS
## MOVE_LIBS= -lkrb -ldes -lcom_err
## For KERBEROS + KRB5
## MOVE_LIBS= -lkrb5 -lcrypto -lisode -lcom_err
## Add "-lhesiod" if HESIOD is defined.
