User Unknown Problems With cyrusv2 Mailer

[~ Andre]

I'm subscribed to this list under andre at neo-anime.org but that's on the 
server that's got the problems. Sorry for subscribing twice.

I just managed to move my userbase to another computer. I changed all 
mailboxes to use the "/" separator, so now mailboxes look like:

user/andre at neo-anime.org

Cyrus is happy as far as I can see. I can use Evolution to pull up my 
mailbox with no problems. I can send mail out with no problems too. But 
when I send a message to myself, I see the following in /var/log/messages:

I'm completely stumped.

If I "cm user/test" in cyradm and send an e-mail to user "test," it goes 
through fine!

It /appears/ to be that Sendmail isn't passing off the domain of the user 
to cyrusv2 but it also appears to look as if Cyrus may have an issue with 
mailboxes being names "user at domain.tld".

Sorry if this is more of a Sendmail question, I'm just not sure where the 
problem may be. Any help would be extremely appreciated.

System config:
Redhat 9
Cyrus 2.1.15
Sasl 2.1.15
Sendmail 8.12.8
