Smarthost problems with internal mailserver

[tobbe]

Hello!

Since I found no matching answer to my question while searching the forum, maybe someone can help me.

Our research group uses an internal mailserver at the moment, accessing it with POP3/SMTP through Thunderbird.
The name of the mailserver is plexus.uke.uni-hamburg.de, the domain of the mailusers is @uke.uni-hamburg.de

My Scalix Box is a normal workstation within the internal network:

Code: Select all

kmtsrv02:/etc/mail# hostname --fqdn
kmtsrv02.gwis.uke.de

My sendmail if configured for a smarthost:

Code: Select all

/etc/mail/sendmail.cf

# "Smart" relay host (may be null)
DSplexus.uke.uni-hamburg.de

Code: Select all

kmtsrv02:/etc/mail# sendmail -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter <ruleset> <address>
> 3,0 tobias@lachmann.org
canonify           input: tobias @ lachmann . org
Canonify2          input: tobias < @ lachmann . org >
Canonify2        returns: tobias < @ lachmann . org . >

Parse1             input: tobias < @ lachmann . org . >
MailerToTriple     input: < plexus . uke . uni-hamburg . de > tobias < @ lachmann . org . >
MailerToTriple   returns: $# relay $@ plexus . uke . uni-hamburg . de $: tobias < @ lachmann . org . >
Parse1           returns: $# relay $@ plexus . uke . uni-hamburg . de $: tobias < @ lachmann . org . >
parse            returns: $# relay $@ plexus . uke . uni-hamburg . de $: tobias < @ lachmann . org . >

What I want to do is to fetch all mails for my users from the internal mailserver plexus into the Scalix-Box, which works fine.

But I'm not able to send any mails, even with a smarthost configured:

Code: Select all

Mar  9 11:41:52 kmtsrv02 sm-mta[3514]: m29Afqn9003514: from=<mengel@uke.uni-hamburg.de>, size=1089, class=0, nrcpts=1, msgid=<29070643.101205059311824.JavaMail.root@kmtsrv02.gwis.uke.de>, proto=ESMTP, daemon=MTA-v4, relay=localhost [127.0.0.1]
Mar  9 11:45:52 kmtsrv02 sm-mta[3522]: m29Afqn9003514: to=<tobias@lachmann.org>, delay=00:04:00, xdelay=00:04:00, mailer=relay, pri=121089, relay=mplexus.uke.uni-hamburg.de. [134.100.102.4], dsn=4.0.0, stat=Deferred: Connection timed out with mplexus.uke.uni-hamburg.de.

Please note Scalix tries to open a connection to Mplexus.uke.uni-hamburg.de, but the Smarthost is plexus.uke.uni-hamburg.de

Seems the Mplexus is the outside mail server

Code: Select all

 kmtsrv02:/etc/mail# host -t mx plexus.uke.uni-hamburg.de
plexus.uke.uni-hamburg.de       MX      0 mplexus.uke.uni-hamburg.de

How can I ensure that every mail, regardless if the user is on the Scalix box or not, is delivered to my desired SmartHost?

Any help is greatly appreciated.
