Thank you for your reply - I meant exactly what I wrote - is it up
to the delivery agent only (Postfix/lmpt in our case) to decide
whether to accept a sender with 8bit characters in the address and if
it does will cyrus digest it. Thanks /per

Does Cyrus Imap support IDN (International Domain Names) as sender
address or is it just the delivery agent that takes care of this?
Not sure, what you mean in detail.
We successfully receive mail from IDN domain senders over EXIM /
Cyrus, while it is typically not a good idea to have any IDN domain
in an email address (lack of "standardization" / compatibility). But
I’m not sure how reliable this works.
Like, for instance, über or gösta.
Then of course is the question if there is support for 8bit mailbox
names as well.
For that what i have seen - not really.
In the past we recommended our users to avoid using i.e. german
Umlauts within folder names, even if they seems to get „converted“ by
cyrus in a working or even proper manner - there will be problems
with several IMAP clients not liking this, which still have problems
with that on their side…
This is what Postfix reports when it tries to deliver to Cyrus:
(SMTPUTF8 is required, but was not offered by host XXX
[/var/imap/socket/lmtp])
(can't see anything relevant in the log from Cyrus)
We want it to be delivered but I cannot figure out how - the sender
address has a "ü" in it.
Really grateful for a hint.
Thanks,
