>Do you know what the pop3d32.exe application does?
POP3d32 provides the POP3 service to POP3 clients, POP3 being a "mailbox
reading protocol".
The Imail "SMTP" process is the "SMTP client" for sending outgoing mail
from Imail to remote "SMTPD servers".
The Imail "SMTPD" process (daemon) is the "SMTPD server" for receiving
incoming mail from remote "SMTP clients".
Each of the above NT processs instances deals with one remote process at a
time.
So if Imail has to deliver a ton of mail, like send out a msg to a mail
list msg of 10,000 remote mailboxes, Imail is going to try to grab every
SMTP client process it can to get the mail out.

The spool process is involved, at least, in writing msgs to the disk,
received from various other processes, for delivery to remote SMTPD
servers. I don't know whether the spool32 process is involved in local
delivery. I think not.

locking of a mailbox that had a ton of aliases could causes pb's since only
one Imail process can had a mailbox lock (not an "alias lock") at any one
time. eg, I've seen, in the Imail logs, mail to my personal mailbox
bounced because the Imail SMTPD process was trying to deliver incoming mail
to my box just as my Eudora POP3 client or SMTP client already had my
mailbox open. The incoming msg was bounced (ie, the Imail SMTPD process,
findiing my mailbox locked, didn't receive the incoming msg and did not
give it to spool32 for queuing and later "local" delivery when my mailbox
became unlocked), but the remote SMTP client came back later and delivered
it without an Imail locking
conflict.
POP32 consuming all memory would be a symptom of tons of simultaneous POP3
clients trying to read their mailboxes. or, something really screwing up so
POP33 just couldn't make progress to its goal, like a massive locking
conflicts.
