I've just doing this on my system and got it to work. The lines in my
main.cf look like this:

#
# SASL Support for servers
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options =

I didn't do anything with mechanism filter. Note the the file
sasl_passwd should be owned by root and have permission bits of 600 set.

I did 'postmap hash:sasl_passwd' here. Not sure if hash: is the default.

Presumably you did a postfix reload after making the changes?

Tony.
