When talking to mail backends, nginx doesn't use SASL for 
authentication as it's believed to be superfluous to use it 
instead of native protocol commands in the non-hostile backend 
environment.

There is SASL support in nginx mail module though, and it happily 
authenticates users with PLAIN, LOGIN and CRAM-MD5 SASL mechanisms 
(as long as http_auth script used is able to handle this).
