Setup DMS fetchmail:

First of all: install fetchmail

# yum install fetchmail

then you need to edit

/opt/fetchmail.script

#! /bin/bash


fetchmail -q


fetchmail -v -K -p pop3 --auth password -f /etc/fetchmailrc --logfile /var/log/fetchmail.log --invisible --smtphost 192.168.1.71  --smtpaddress serviva.com -d 300

...

then edit  /etc/fetchmailrc

defaults

proto pop3

...

defaults

proto pop3

set logfile "/var/log/fetchmaillog"

...

poll pop.1und1.de

...

proto pop3

...

user "serviva@epmanagement.eu"

...

pass "mypassword"

...

is "serviva"

...

keep

most important setting is “keep” to keep the polled emails on the server. If you omit this, the polled mails will be deleted from the pop3 (exchange) server which might result in a shitstorm.

The file fetchmailrc can hold as many mail accounts as you like.

create User fetchmail

# adduser fetchmail

...

# passwd fetchmail

...

# usermod -aG wheel fetchmail

now make fetchmail the owner of the file /etc/fetchmailrc

# chown fetchmail /etc/fetchmailrc

And set that file to exclusive for user fetchmail

# chmod -v 600 /etc/fetchmailrc

then try if the user is working

# su fetchmail

whilst in the user fetchmail create a cronjob

# crontab -e

...

30 * * * * /opt/fetchmail.script

Result:

Fetchmail picks up new emails from the defined email inboxes and delivers them to the postfix of DMS. This happens every 5 Minutes and the whole job is reinitiated every 30 minutes.

There is a lot more detail hundreds of fetchmail tutorials or the man page of fetchmail. This is my own cheatsheet and is by no means complete or all encompassing.
