Postfix, Cyrus and Fetchmail.
 

I have a problem with the above setup after rebooting our linux server today. The basic problem would seem to be that all the mail use to come through on the mail logs, as bert@fred.co.uk, and was then routed correctly. After a reboot today, all the mail now comes through as bert@localhost and as a result PostFix complains it can't route it. Nothing was changed prior to the reboot.

I'm wondering with a prexisting change or update, has taken effect as a result of the reboot, but does anybody have any idea what it might be.

The System is SuSe Linux 9.1.

The Mail System, is Fetchmail, Postfix and Cyrus.

Any help most appreciated.

Anybody any ideas at all, this is causing me quite a few problems??

what's the output of Posting the relevant postfix logs would also help.
