Web Hosting Toolkit Qmail and Vpopmail

Qmail and Vpopmail

  To use WHT's email functions you need Qmail and Vpopmail. They have to be run under tcpserver. Do not hurry up to give up. There is a wonderfull site http://qmailrocks.org, where the installation process is explained step by step. The site will guide you through the installation of many usefull programs including the required Qmail and Vpopmail.

  If you're new to Qmail, better install it on some test server first. Although I have gone through the process many times, I still sometimes screw it up.

  The main advantage of that mailing system is that you can have many virtual users (not system ones) with separate mailbox (maildir), but not just one mailbox receiving the mail for all the email addresses (aliases). And of course Qmail pretends to be really fast.

  The only dissadvantage of this installation is that it does not allow roaming users accessing their mail. To fix the problem:

In part 6 - Vpopmail first create group vchkpw and user vpopmail.

# groupadd -g 89 vchkpw
# useradd -m -g vchkpw -u 89 -d /home/vpopmail vpopmail

# ./configure --enable-logging=e --enable-roaming-users=y --enable-relay-clear-minutes=360 --enable-tcpserver-file=/home/vpopmail/etc/tcp.smtp

but not ./configure --enable-logging=p as described in qmailrocks.org

and add a cron job

# echo "40 * * * * /home/vpopmail/bin/clearopensmtp" >> /etc/crontab

In part 11 - Finalize Qmail to start qmail-pop3d with the command qmailctl start the file /var/qmail/bin/qmailctl must look like that:

#!/bin/sh
# For Red Hat chkconfig
# chkconfig: - 80 30
