Hi All,

I'm working on getting Postfix to authenticate SMTP users from a MySQL 
DB which stores encrypted passwords.  Various how-to's recommend 
cyrus-sasl, but it seems that to use it for encrypted passwords you need 
the checkpw.c+sql.c patch.  The only version of this patch I can find 
( is for cyrus-sasl-2.1.19.  Has the 
patch been merged into later versions of cyrus-sasl, or do I need to use 

Also if anyone has pointers on getting this going, I'd be happy to hear
