Qpopper uses the standard UNIX mail box format, or
mbox for that matter, which retrieves e-mail from a
single file.. while this is not a problem, it creates
a problem if a user is downloading e-mail, and for
some reason, say a power cut, telephone line
instability or sthing like that, he gets disconnected,
he may not be able to re-download his mail because of
a pop-lock file that was created for his initial
session.... that means a UNIX admin would have to
manually copy all temp e-mail back to the mbox file,
then delete the lock file.. which can be tedious if u
have a large network using your mail server as their
primary mail hub....
Qmail, is an MTA, but also has a POP3 server called
qmail-pop3d, which uses a system called Maildir, where
mail is stored in the user's home directory, in a
directory called Maildir, each as a separate file...
similar to the way Eudora stores download e-mail...
here, each file is downloaded separately, without need
for a pop lock sessions, and if a user gets
disconnected, he may return and continue where he left
off.... which is more reliable i think....
of course, Maildir can only be used with MTA's that
support Maildir delivery, which i think, at the
moment, are Postfix and Qmail...
i still need some ideas on qmail-pop3d logging and TCP
Wrapper behaviour, though...thanks..

i have recently moved from Qualcomm's Qpopper to Qmail's qmail-pop3d, and have two problems i badly need some help on:
first, connecting to port 110 takes about 4 to 5 seconds because i am using TCP Wrappers and /etc/hosts.allow ... removing the TCP Wrappers in /etc/inetd.conf will enable me to connect instantly to port 110, but somehow, will not open the user's Maildir ... i have looked at permissions of both qmail-pop3d and inetd, but with no luck... any ideas..?
second, after moving to qmail-pop3d, i can no longer log POP'ing activity of my users.. i can only log qmail-popup connections in /var/log/messages .. my tries with /etc/syslog.conf have proven fruitless....
Haven't seen that package, but I gotta ask.... If the qpopper did all that for you, why switch?
Qpopper has been utterly reliable for me.
