/* Important notice: defining MAIL_USE_FLOCK or MAIL_USE_LOCKF *will

/*
* Modified January, 1986 by Michael R. Gretzinger (Project Athena)
*
- * Added POP (Post Office Protocol) service. When compiled -DPOP
+ * Added POP (Post Office Protocol) service. When compiled -DMAIL_USE_POP
* movemail will accept input filename arguments of the form
* "po:username". This will cause movemail to open a connection to
* a pop server running on $MAILHOST (environment variable). Movemail
* must be setuid to root in order to work with POP.
- *
+ *
* New module: popmail.c
* Modified routines:
* main - added code within #ifdef MAIL_USE_POP; added setuid (getuid ())
- * after POP code.
+ * after POP code.
* New routines in movemail.c:
