Hello, I found this in my logfile this morning and was wondering (at least) two things. (1.) is the ".pue.de" entry at error, since it is not specifying a fully qualified host name? (2.) is due to the (assumed) error of (1.) the delivery to the "mout.kundenserver.de" (and 212.114.86.56) not performed?
Or is the reason simply because of the IP address mismatch error below? Thanks for helping me understand. ...
