[SOLVED] Relaying not working after update

[TobiTobs]

Hi everyone,

after a recent update all relaying to my mailserver stopped.
In the logs I can see that mails get relayed to localhost (127.0.0.1) and I can find them unter /var/mail/mail but obviously they should be sent to the mailserver.
Snippet of the log file of one mail:

I did not change any config files etc - any idea what this could be?

Thanks in advance!

Solved: I don't know why but I use the domain name as host for relaying and that went bezerk...with a different name it is now working - although it did work like this before!
