you are really a champion!

This nicely avoids implicitly instructing users to hardcode their credentials in a script, so in this sense it's probably good that it's underdocumented (maybe deliberately so).
This is great, and now I am embarrassed that I did not just try it.
Querying the password at runtime is by far better than hardcoding the
password and the mechanism in the script. Obviously, sometimes I am
trying to read too much or am thinking too complicated instead of just

Thank you very much for this insight. This is important and really

I think I saw something like that during my research. For example,
imapsync provides --proxyauth1 and --proxyauth2 command line parameters.

I see. This makes sense.

Again, thank you very much. You are right, getting it from the Perl
installation is by far easier. Before actually opening it, I'll copy it
to another place and work with the copy (in case I accidentally alter it
while looking at it).
I can't tell how grateful I am for your support (and for providing Cyrus
imapd in general). IMHO, this is still the best IMAP server for small
and large installations!
Thank you very much again,
