SuSE Linux: Versions since 6.3
sendmail
<xy@t-online.de>... Deferred: Connection refused by mailin03.sul.t-online.de. Message could not be delivered for 5 days Message will be deleted from queue
First, register on the homepage of the provider for smtprelay.t-online.de under http://www.t-online.de/service/inhalte/kemsviea.htm .
Now you can configure the file /etc/mail/mailertable to have messages to T-Online addresses sent via this relay. As for the rest of messages, sendmail will continue to send them directly.
For this purpose, insert the following entry in the file /etc/mail/mailertable:
t-online.de smtp:smtprelay.t-online.de
In order to validate the changes, enter the following command as administrator root:
SuSEconfig rcsendmail restart
If you observe that e-mails to other domains cannot be delivered either, then you can send all e-mails via the smtprelay. In this case, do not proceed as described above but edit the following variable in the file /etc/rc.config.d/sendmail.rc.config instead:
SENDMAIL_SMARTHOST="smtprelay.t-online.de"Finally, execute SuSEconfig and rcsendmail restart once again.
Please note that this solution approach exceeds the scope of our free installation support.
