ILIAS-7-Install-Tutorial for Ubuntu 20.04

Postfix

With this little tutorial I show you how to enable email support for your server. It supports only forwarding, that means, all mail traffic will be forwarded to a mailaccount of your choice. For example, if www-data wants to send me a message, it will be forwarded to wolfgang.huebsch@gmx.de. You can also add a alias like this: wolfgang.huebsch@bbs-ilias.de -> wolfgang.huebsch@gmx.de

Does your Server provider supports a SMTP-Relayserver?

Please find out if your server provider supports a SMTP-Relayserver
The hosteurope product Virtual Server 10+ does so. More infos here: https://www.hosteurope.de/faq/server/virtual-server/vs-mail-relay/
If your provider provides not such server, there should be at least the possibility to set a RDNS entry.
In case of doubt ask your provider

If yes

Find out the adress:
- For Hosteurope-KIS: Produktverwaltung->Virtual Server 10+->Login->Einstellungen->SMTP-Relayserver
- Example: n1smtpout.europe.secureserver.net

If not

Please check, if your RDNS is configured correctly. For example, visit this site: https://www.debouncer.com/reverse-dns-check
Fill in: bbs-ilias.de
A good result is:

FCrDNS test result:
176.28.8.65 resolved to bbs-ilias.de;
bbs-ilias.de resolved to 176.28.8.65;
rDNS if forward confirmed.

Generic PTR record test result:
bbs-ilias.de not looks like generic.

If not, check out this page: https://bbs-ilias.de/ilias/goto.php?target=pg_31_187&client_id=info

Install Postfix

apt-get install libsasl2-modules bsd-mailx postfix
Choose Internet-Site
System Mail-Name: bbs-ilias.de

Configure main.cf

nano /etc/postfix/main.cf
Change the follwoing lines like this (search for them with STRG+W):
- myhostname = bbs-ilias.de
- mydestination = bbs-ilias.de, localdomain, localhost, localhost.localdomain, localhost
- mailbox_size_limit = 10240000
- If you use a SMTP-Relayserver: relayhost = n1smtpout.europe.secureserver.net
  - Otherwise leave as it is
Check the syntax: postfix check
Reload service: systemctl reload postfix

Configure Mail-Aliases

nano /etc/aliases
Add your forwarding mailadress like this:

#
# Mail aliases for sendmail
#
# You must run newaliases(1) after making changes to this file.
#
 
# Required aliases
postmaster:     someadress@someprovider.com
MAILER-DAEMON:  someadress@someprovider.com
 
# Common aliases
abuse:         someadress@someprovider.com
spam:           someadress@someprovider.com
 
# Other aliases
clamav:                 someadress@someprovider.com
root:                   someadress@someprovider.com
wolfgang.huebsch:              someadress@someprovider.com

Use TAB-Stop to add spacing (not like above with space key).

Activate aliases: newaliases
Send a testmail: echo "ILIAS is the best system" | mailx -s "Test-Mail" wolfgang.huebsch@gmx.de

Find errors

nano /var/log/mail.log
Have a look for entries like this: No SMTP service 554-Bad DNS PTR resource record
That means your Reverse DNS is not set correctly for our domain (bbs-ilias.de). You can aprove this also here: https://www.dnsqueries.com/en/reverse_lookup.php
Of course you can find any other error there
