Hi again,
minutes after posting I found something for my LMTP-question:
Where may I specify the port number of the backend server's LMTP-port? I suspect that the missing port number implies that the receiving LMTP-backend server uses the same port and so this would lead to a loop, hence the loop error?!
Just add "port=<backends LMTP port number>" in the passdb section like:
passdb { args = proxy=y nopassword=y port=25252 driver = static }
So I am worrying about the IMAP+GSSAPI part...
Cheers, Dirk
