Email address as login name - Cyrus 2.2a + SASL2

[Erin]

I am currently playing with Cyrus Imapd 2.2a and SASL2 (2.1.13) using
auxprop mysql.

The only problem I am having is when I try to log into Cyrus via pop3 or
imap SASl will fail to authenticate, it seems to be stripping the '@' from
the email address.

I know I probably just overlooked something small.

My log is below;
