How to install and configure UW-imapd on Fedora Core Linux with SSL enabled

1. Download and install the newest OpenSSL. At time of writing, this is openssl-0.9.8g.tar.gz. To install:

   ./config; ./make; make test; make install

   (check the "make test" output for errors before "make install).
2. Create certificate for imapd to use. Change directory to /usr/local/ssl/certs/ and type

   openssl req -new -x509 -nodes -out imapd.pem -keyout imapd.pem -days 3650

   To avoid warnings, the "Common Name" you enter should be either your FQDN or IP address.
3. Download and install the newest UW-imapd. At time of writing, this is imap-2006k.tar.Z. You can also just download imap.tar.Z to get the latest build. To unack, use gunzip. To install, I used:

   make lnp PASSWDTYPE=pam SSLTYPE=unix

   The build type (lnp) will vary between operating systems. This one worked on Fedora Core 1 (Yarrow). This make command will create the imapd binary as "[source_dir]/imapd/imapd". You can leave it in place or copy it to directory such as /usr/sbin/. I left it in /usr/local/imap-2006k/imapd.
4. Configure xinetd to start the imap and imaps daemons. Note that both are run by the same binary "imapd." Create a file named "imap" in /etc/xinetd.d/
   

    
   service imap 
   {
   	disable = no
   	socket_type = stream
   	wait = no
   	user = root
   	server = /usr/local/imap-2006k/imapd/imapd
   	log_on_success += HOST DURATION
   	log_on_failure += HOST
   #	bind = 127.0.0.1
   }
   

   
   Create a file named "imaps" also in /etc/xinetd.d/
   

   service imaps
   {
           disable         = no
           socket_type     = stream
           wait            = no
           user            = root
           server          = /usr/local/imap-2006k/imapd/imapd
   	log_on_success  += HOST DURATION
   	log_on_failure  += HOST
   }
   

5. Configure PAM to accept authentications from the imapd. Create two identical files containing the text below, and name them "imap" and imaps":
   

   #%PAM-1.0
   
   auth required pam_unix_auth.so
   account required pam_unix_acct.so
   password required pam_unix_passwd.so
   session required pam_unix_session.so
   

6. Start/Stop your imap and imaps services with /etc/rc.d/init.d/xinetd restart.
