this is the part I was talking about. If you have virtdomains: yes,
imapd adds a realm to all usernames without realm, so on my server the
real username used with sasl is username at servername.domain.com, which I
have in my user database, so I can log in.

I think your imapd will try to use a username like this:
my.admin at servername.testdomain.com to log in. hmm, have you set
defaultdomain?

Here the strange thing is that the servername part is cut off, so I
cannot login like this. Same like you.

What I don't understand is how imapd constructs the the realm. I asked
on this list four days ago (cyrus sasl realm problem), but I still don't
understand it really :(

that's what I received from Brad Crotchett:

On my system I can login from localhost on the localhost interface, and
from external on the external interface. I can live with that, although
I would like to understand what's happening.
