i have set up a GO 6.1 instance on Debian Jessie according to the (revised) how to that can be found here in the forum
Outgoing mail works fine, but incoming mail for "email@example.com" (recieved via fetchmail from a catchall account) does not get delivered to the corresponding local "firstname.lastname@example.org" mailbox, but is looping instead for a few roundtrips between mta.outside.com and my machine until mta.outside.com recognizes the mailloop and generates a deliyery failure notification.
Can anybody give ma a hint, what piece of configuration may be missing?
Also i have no idea, why in step 5 of the how to the main.cf parameters myhostname
are beeing commented out (and thus set to the default values).
Any help or hint is appreciated...
