Postfix, Sasl & Pam

[Jack Fredrikson]

Hi;
I get this error:
dovecot: pop3-login: Disconnected (no auth attempts): rip
In googling this, it indicated that the problem might be in postfix. So I poked 
around and became puzzled as to how postfix discovers my 
/etc/postfix/sasl/sasl.conf file, since it's not referenced in main.cf. Please 
advise.
TIA,
Jack
