[NTLUG:Discuss] Sendmail

[Jim Williams]

You need to open up a POP or IMAP port. RedHat's default IMAP/POP 
servers are in the IMAP RPM. Installation would be similar to the following:
Download newest IMAP RPM from RedHat update site.
Install RPM with an "# rpm -ivh imap........." command
Use chkconfig to insure xinetd and pop3 are initialized at boot up:
"# chkconfig xinetd on"
"# chkconfig ipop3d on"
Use "# chkconfig --list" to list all the initialization configs and 
verify you are setup correctly.
Then verify that the xinetd server is running  so you don't have to reboot:
"# /etc/init.d/xinetd start"
Your users should now be able to access e-mail boxes with any POP3 mail 
reader application, assuming you're not blocking them with a firewall.

Also you need to be aware the RedHat by default restricts the sendmail 
daemon to the localhost or loopback IP only. If you ever do want 
sendmail to receive incoming SMTP connections you must edit the 
/etc/mail/sendmail.mc file, comment out the line near bottom of file 
that restrict it, and recreate your sendmail.cf config from it. If you 
wish to do so,  ask and I'll relate how that is done as well.
