Looks like a Postfix misconfiguration. You should compare the output of
"postconf -n" with "postconf -d" to see which settings differ from
default.
Are you running Postfix in chroot mode?

Cyrus SASL and Cyrus-IMAPd don't have that much to do with each other.
It is just that both originate from same university
(http://asg.web.cmu.edu/cyrus/) and that SASL is used by Cyrus-IMAPd as
the authentication layer.

Maybe saslfinger is helpful for you
http://postfix.state-of-mind.de/patrick.koetter/saslfinger/
Patrick - author of one standard Postfix book:
http://www.postfix-book.com/ - has an older howto on his site which may
be partly helpful. Running a complex mailserver (Postfix + Cyrus-IMAPd)
with virtual domains I think it would be good to intensively read the
available documentation and to get the book.
