Sieve: "@" in user names wont work?

[Edward Rudd]

I've had this problem as well..but with IMAP (never checked sieve)..
The issue is cyrus imap checks the domain and if it is not the "Default"
domain or listed in the loginrealms: config line in /etc/imapd.conf. 
However, the check seems to only occur when using a sasl mech other than
login with IMAP..   As sieve uses sasl as well this is where the problem
is.. (now that you are totally confused..)
I've attached the patch I created to fix the issue with IMAPd.
Basically put loginrealms: * in /etc/imapd.conf and it'll all work..
otherwise you will have to put every domain on your server in
loginrealms.. (see man imapd.conf)
