IMAP and outlook 5$!&85!!

[John Seth]

I have the maildir patch for pine4.44... I'm not certain it'll fix IMAP,
but if you want to give it a try, let me know and I can give you the URL
to download it.

   My company recently switched from standard RedHat POP3, to Qpopper,
to Courier-IMAP.  Our server load itself, has gone from a steady
4.0-10.0 to 0.5 - 3.0... sounds amazing, but our mail systems have never
been more stable.  Our customers don't have access to IMAP, and we're
only pondering opening IMAP for users to utilize webmail.  Being the
webmaster, I've suggested SquirrelMail, since I use it on my own system.
However, the SysAdmin is worried that 12,000+ users with access to an
IMAP based webmail program will stifle the system.  So for now we're
using (the rather inferior, IMHO) VisualMail.  If anyone has experience
using SquirrelMail, IMAP, POP3, at the same time, I'd be interested in
knowing how your mail systems handled the loads.

Thanks,

   Tony Evans (aka: "John Seth")

: It wasn't hard but you have to get an older version of uw-imap 'cuz
there
: doesn't seem to be anyone maintaining the maildir patches and the guy
at
: UW doesn't want to handle it in his source tree...
:
: The place that I found it is: http://greboguru.org/qmail/
:
: I've been hacking around with the stuff tonight and I think that I can
get
: imap-2001a to build with the patches but I had to change stuff in
: src/osdep/unix/Makefile to point to the right place for the openssl
: includes.  I changed line 33 to read:
: SSLINCLUDE=/usr/include/openssl
:
: That worked on Mandrake 8.1 but will probably have to be changed if it
: lives elsewhere.
:
: I then did a 'make slx' and it compiled.  I'm going to play with it
tomorrow
: at work to see what happens.
:
: You will have to get imap2001a from:
: ftp://ftp.cac.washington.edu/imap/old/imap-2001a.tar.Z
:
: and the patch from:
: http://greboguru.org/qmail/imap-2001a.4-patch-with-delete-fix
:
: Then untar the imap source:
: tar xvfz imap-2001a.tar.Z
:
: Then patch the source:
: patch -p0 < imap-2001a.4-patch-with-delete-fix
:
: Then 'cd' to imap-2001a
: change line 33 as mentioned above to:
: SSLINCLUDE=/usr/include/openssl
:
: Type 'make slx' to build the thing
:
: Copy imapd/imapd to your favorite location for such things.
: Fix your xinetd.conf (or xinetd.d/imap) file for the right
: path for imapd, 'killall -HUP xinetd' and you're in business.
:
: I may have a problem with a user that seems to still generate
: mbox files.  I think it has to do with not having a proper 'Maildir'
: when he started.  There is mention of a kludge on the page to remove
: the 'mbox' driver.  I may just do that.  Of course, the workaround is
: to send email to each user before he tries to copy folders to the IMAP
: server :-).  It seems that if the thing doesn't find a 'Maildir' in
the
: user's home directory with the appropriate 'cur', 'new' and 'tmp'
directories,
: it tries to do 'mbox' format.  This really annoys outlook when you try
to copy
: folders to the IMAP server.  I managed to crash my boss' Outlook many
times
: before I left today but I think this is the reason.  I will try to
remove the
: 'mbox' driver in the morning.
:
: Sorry for the stream-of-consiousness vomit-stream but I just collected
my
: thoughts
: for the morning and I will probably read this message when I log in to
get
: started.
:
: I also found a program that purports to convert mbox to maildir format
at:
: http://qmail.sgi.net/qmail/mbox2maildir
:
: You'll have to read the file and probably get 'qmail' from
: http://www.qmail.org/
: and read and understand 'maildir2mbox' and experiment a lot before
trying this
: in a production environment.
:
:
: Hope this helps...
:
: I'm VERY tired, now.  I'm going to bed.

: Cheers!
