The RFC does say that after logging in the server acquires an exclusive lock, but it isn't clear that this prohibits multiple access per se. There are servers which permit simultaneous POP access by the same user, and there's nothing wrong with this, as long as each POP client gets a consistent view of the spool. So if client A deletes a message, client B's session is unchanged; if A deletes a message enters update state, B's session is still unchanged; the message still exists. But most POP servers don't bother with this, since it's more complex and usually not needed.

Agreed. Either duplicate the mail in the LDA or let the LDA do the basic sorting for you and sort it into spools for different accounts. I prefer the latter but depending on exactly what you're doing, the first might be better. Justin
RE: Multiple pop requests on the same account
Good point and I wasn't sure why ipop3d wasn't giving me the same error. We probably will look into setting up some type of mail copy, but I believe we will attempt to an imap implementation first.

Well, ipop3d at least won't give you a locking error, but manages this by simply killing the previously logged in POP session every time a new one connects. Since in principle the two POP sessions could be issuing incompatible updates to the spool, but neither is likely accept unexpected changes happening out from under it, it's hard to know what the "right thing" is. If this is all in support of some kind of script-driven automatic processing of certain specific accounts, it might be easier to .forward them or procmail them to clone all incoming mail to two different mailboxes and then process those mailboxes via independent POP sessions. -- Clifton -- Clifton Royston -- LavaNet Systems Architect -- [EMAIL PROTECTED] "If you ride fast enough, the Specialist can't catch you."

RE: Multiple pop requests on the same account
We have serveral e-mail with things in them that we'd like to pop off at the same time and process the different e-mails concurrently. When two processes are popping at the same time, I get a busy/lock error message. I assumed qpopper could do this since other pop servers don't have trouble with it.
