I don't think there's anything to fix here.  The code looks fine as is,
just docs missing.  Unless we want to explicitly *not* accepted
un-bracketed "ip6-address ':' port"?  But forbidding that seems silly,
considering it requires adding code to remove functionality.

This code hasn't changed since 2012, when it was refactored by 306099b. 
It's in the same state (modulo tabs/spaces change) on 2.5 and master
branches.  The 2.4 version is significantly different, as it didn't get
the refactor (but that doesn't appear to be a problem here).

I'm scouring the thread trying to figure out if there's even a problem
being reported (other than lack of docs) and I can't see it.  It seems
to have gone like:

Sebastian: How do I do this?
Various: It's not in docs, but try this...
Sebastian: I tried this and it worked

Sebastian, is there anything you tried that *didn't* work, and if so,
what happened?

Cheers,

ellie

Re: Is there a way to send custom warning to all IMAP users?

OK, that worked.  From cyradm

setinfo motd "Email no longer active here.  Please try mynewserver.mydomain.net"

Just shutting down the service is also a solution, but given over 600
unique users have logged in today, I'd rather not dump that load on
the service desk.


When we migrated some of our users to Google Mail, we placed a final 
message in their Cyrus mailbox.  When they login, they can see "You've 
been migrated to Google!", and the message tells them how to find their 
email on Google.


To bypass email routing, you can use the "deliver" program on the Cyrus 
server to drop the message in the Cyrus mailbox.


Let me know if you need more information.

Thanks,
Andy

You can set a system wide motd, but it's unlikely all clients will honor
it.

See the cyradm manpage.
