Courier Email Server
This is a small howto on how to install an imap-Server with Courier-Imap, SSL-Encryption and grabbing all the other mail-accounts with fetchmail. Procmail is responsible for delivering the Mails to the different Users.
You can fetch your Mail from this IMAP-Server with every Mail-Client capable of communicating with IMAP.
For testing purposes you should create an own email-account, e.g. www.gmx.de.
For more complex setup see Creating a Linux Mail Server (Postfix, Procmail, Fetchmail, SpamBayes, Courier-imap, Mutt, SquirrelMail)
pacman -S fetchmail procmail courier-imap
Just make .fetchmailrc in your home-directory and add the following lines:
poll pop.gmx.de with proto POP3 user "username" there with password "passwd" is "morphus" here mda "/usr/bin/procmail -d %s"
- username - Your username on the pop3-server
- passwd - Your password on the pop3-server
- morphus - Your local account where the mail belongs to
Create and edit .procmailrc in your home-directory
PATH=$HOME/bin:/usr/bin:/bin:/usr/local/bin:. MAILDIR=$HOME/Maildir/ DEFAULT=$HOME/Maildir/ LOGFILE=$MAILDIR/procmail.log
Now secure your .fetchmailrc since they contain passwords
chmod 600 .fetchmailrc
First Try with procmail and fetchmail working together
Send some bulk-mails to your test-account. Then run
Fetchmail echos the communication with the pop-Server and after the run finished you should find some files in your Mail-Folder with the Mails.
Configuring Courier Imap
Run the command
with each user you want to have an imap-account
And now just start courier imap with
You should be able to connect from your console with telnet like this:
[morphus@spielemorph ~]$ telnet 192.168.6.1 143 Trying 192.168.6.1... Connected to 192.168.6.1. Escape character is '^]'. * OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE THREAD=ORDEREDSUBJECT THREAD<code>REFERENCES SORT QUOTA IDLE ACL ACL2</code>UNION STARTTLS] Courier-IMAP ready. Copyright 1998-2004 Double Precision, Inc. See COPYING for distribution information. 1 login morphus passwd 1 OK LOGIN Ok.
This means everything is okay and you can connect. Your mail should be delivered to this Maildirectory and you should be able to connect with any imap-capable program.
Doing some cron-jobs
Just add the fetchmail -av command to the users cron-list, e.g. every 10 minutes he should grep the emails
'/10 ' ' ' * /usr/bin/fetchmail -av
Add /etc/rc.d/courier-imap to your rc.conf in the DAEMONS section.
