- No that won't help on startup. That flag is used to lie to the POP
- client telling it the mailfile is closed before it actually is.
- This can be used to aviod delays when quiting a POP session, due to
- VMS MAIL reclaiming deleted space while closing the mail file.

- 3.1 Rev-B isn't faster, but Eudora's timers will be happier with it.
- It sends the response for the PASS command before it open and parses
- the mailbox, a slight deviation from the RFC. (a bit of a gray area).

- Btw, there is nothing in the POP protocol regarding any timeout
- periods.

-
- Keep in mind the POP clients are validated via LOGINOUT.EXE.
- SYLOGIN.COM and LOGIN.COM are executed as a NETWORK job.
-
- You'll want to
- $ if f$mode() .eqs. "NETWORK" then ...
- around statments POP doesn't need.
