[otrs] FQDN behinded a NATed router?

[Michael Belz]

1.

In order to send mail with the correct from: header, you must tell
sendmail to use <user at example.net> rather than <user at bsd.home>.

So basically your .mc file should contain an entry like this...


MASQUERADE_AS(`example.net')dnl

You must then generate a new Sendmail.cf file, and restart sendmail.

Other important things to mention

2.

Unix/Linux will add whatever user to the front of that e.g.
otrs at example.net : )

This will properly send mail to the correct domain so your external mail
server will allow authentication.


One other thing you may need to do is this 

I believe it is the defaults.pm config file and change the "FQDN" info
to match what you want your notification master to be. If you do not
change this your notifications will be from otrs at 192.168.1.2 the ip of
the otrs machine! Hope this helps.

Thank you,

We have our OTRS server on our internal LAN, which is behind a router 
running NAT.  The actual mail server is outside the LAN, and we POP and 
SMTP mail from there.  The actual FQDN is company.com, and the OTRS 
server is called chuckles, but the DNS is NOT exported beyond the
router.

I have tried chuckles.company.com, but of course there is no 
chuckles.company.com on the internet, nor does user at chuckles.company.com

actually return mail to the correct user.

I have tried chuckles.localdomain, but then I (and other AGENTS) get new

ticket notification mail with the return address of 
otrs at chuckles.localdomain.

The actual POP3 email address is helpdesk at company.com (which resides on 
our external mail-server) so our normal return mail (notifying the 
CUSTOMER of their assigned, for instance) work properly.

Can someone take all of this, and tell me which FQDN I should put in 
Config.pm.

Thanks,
   Steve
