HowTo IMAP-2002 ON RedHat 7.3

My reasons for doing this (and the contents of this file)

I want to have all mail stored in ~/.imap
I want to have all folders default to mbx format
I want to have SSL/TLS
Compile UW-IMAP
Install IMAPD

TO HAVE DEFAULT mbx FORMAT FILES

Edit src/osdep/unix/Makefile and change the following two lines

-CREATEPROTO=unixproto
-EMPTYPROTO=unixproto
+CREATEPROTO=mbxproto
+EMPTYPROTO=mbxproto

TO HAVE ALL FOLDERS DEFAULT TO ~/.imap

Edit src/osdep/unix/env_unix.c and change the line near the top

-static char *mailsubdir = NULL; /* mail subdirectory name */
+static char *mailsubdir = ".imap"; /* mail subdirectory name */

Then in your Procmail file do this as a default rule to send all messages to your INBOX

:0
*
| /usr/sbin/dmail +INBOX

TO HAVE SSL

Create your certificates and store them in /usr/local/ssl/certs
Using self-signed certs may cause problems with some clients
Edit src/osdep/unix/Makefile and change the following line

-SSLTYPE=nopwd
+SSLTYPE=unix

-SSLDIR=/usr/local/ssl
+SSLDIR=/usr/share/ssl

COMPILE IMAP

On RedHat 7.3 do: make slx SSLTYPE=unix
Using SSLTYPE=unix is not standards complient. To be standards complient you'll want to use SSLTYPE=unix.nopw

INSTALL IMAPD

Now that IMAPD is compiled you'll need to copy dmail/dmail, imapd/imapd and ipop3d/ipop3d binaries into the correct location to use them. Refer to /etc/xinetd.d/imap for this location.

UPDATE

I'm no longer using UW-IMAP. It's great, but there were a few things I felt weren't up to what I was afer. In particular, the method of sub-foldering was a drawback I tried to overlook, but in the end felt it was more of a nuisance than not. I'm not dissing the UW guys - they've done a great job with UW-IMAP - it's stable and does very well what it claims to. It just wasn't the one for me.

I've moved to using Cyrus-IMAP. It's not for the faint hearted, but it's got a lot of things a good sysadmin would like.
