Excellent, that's what I like to hear :)

Wow, that wouldn't work for us at all.  I did have to put -p 1 on the
syncserver command line in cyrus.conf before it would let me authenticate
at all, and nothing but DIGEST-MD5 worked for me.  Also, 
Authen::SASL::Cyrus worked fine, but then the connnection was encrypted and
I had to try and pipe all the IO through it as well, which I couldn't be
bothered with making pipe nicely.

Thanks for that.  I probably should make it try both in order or something
funky like that.  Maybe an "auth_digestmd5" and an "auth_plain" function
which are tried in that order.
