About:
Cucipop is a fast and robust implementation of the RFC1939 POP3 protocol. It supports both BSD-type and SysV-type mailbox formats, works reliably over NFS.and it includes an option to defeat "leave mail on server" clients. Cucipop can run from inetd or as a standalone daemon.

[»] cucipop not locking mail
by John Leach - Dec 16th 2001 05:25:29

cucipop appears to violate RFC1939 in that it allows
more than one connection to a mailbox
simultaneously.
I say 'appears to violate' because I've tried a couple
of different ISPs using cucipop and they both had this
behaviour. It may be a configuration option.
My tests indicated that (a) a second connection to a
mailbox will succeed when the first one is still active
(ie before it has issued a quit); and that (b) if you
have more than one connection active at the same
time then if both connections are deleting email
independently then the first connection to quit will
have its deletions accepted and the second
connection will have its deletions ignored.
Is there a way to write a pop client so that multiple
connections can safely access the same mailbox?

    If you telnet to port 110 of cuci.nl, you'll find
    that they are using v2.00 of cucipop...

    The author says that he's going to release it soon
    but it might help if you sent mail to srb@cuci.nl
    to register your interest!

[»] Cucipop
by Nicko - Jun 9th 2000 15:08:26

This is one of the best pop3 servers I have found. One error that I have run into, and have not found the solution to yet is this:

Err Locking [user]'s mailbox.

When this happens the user is able to pop off their e-mail, but the e-mail that is downloaded stays on the server. Even my webmail program has the problem. Has anyone else run into this problem or found a solution to it?

      Since 26 -r-xr-sr-x 1 bin mail 26368 13 âåð 21:11 /usr/local/libexec/cucipop
      /var/mail should writable by group mail, which has GID 6.

        Uh, be more specific. I've run this:

        chown go-w /var/mail
        chown root:mail /var/mail
        chmod 755 /var/mail

        Now, according to what you've just told me, that should have worked, right?

          Oops! Here's the magic incantation you're probably looking for in order to fix the problem with duplicate messages not getting deleted: chown root:mail /var/mail chmod go+w /var/mail chmod 750 /var/mail Hurray, problem fixed. :)

[»] Documentation
by C.J. Collier - Nov 16th 1999 14:02:11

My ISP has been using cucipop as an alternative to qpopper for quite some time, and it has been working very well besides the fact that I can't find any documentation on it. This may just be a fault of my own, though. I am trying to kludge something togeather to make the daemon ignore all messages with the IMAP header:
DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA.
I'm sure this is not specific to cuci, but it is hard to know where to start without any documentation. If anyone knows of a mailing list, please feel free to post it.

[»] inetd
by MH720 - Jun 1st 1999 22:05:18

Don't even think about running this as an inetd service if you plan on running cucipop on a large site, inetd will hose when you start getting alot of concurrent users. We use S99local to kick off /usr/cucipop/cucipop -Y -q , and have at times 70+ concurrent users checking email on a p2 300 / 128mb. cucipop works VERY well for the smallest to the largest (20000+ user) sites, but watch out for inetd, same goes for the sendmail/exim MTA!

[»] GPL
by Jordan Mendelson - Mar 23rd 1999 06:44:10

This software seems to violate the GPL. There is source that was taken directly from procmail which is under GPL, yet cucipop was not placed under GPL (missing COPYING file and no mention to GPL).

    This sentence should have read: "from procmail which is also available under the GPL".

    > cucipop was not placed under GPL

    Which is entirely correct and in no way violates the GPL considering the fact that the author of cucipop happens to be the author of procmail as well, and is therefore permitted to rerelease any part of the procmail sources under any license he sees fit.

[»] cucipop
by JobeR - Mar 17th 1999 15:07:52

We had a similar problem running 6000 users on a mail machine, ipop3d was killing our machine, easily sending loads over 25. Installed qpopper, but there was many problems with that, and people were not able to get all of their mail. We now run cucipop, and the configurability, and efficiency are unnmatched. Loads now hold at around .5 for the entire mail machine!
