I've been at this tutorial for days and it allways bring me to this.
12.4. Check if SMTP AUTH works
http://postfix.state-of-mind.de/patr...ilclients.html

when I ran the check, I get 535 Error: authentication failed

the tutorial allso refers to a file needed called cyrus-sasl-authd ,as you can see below I dont have that file on the system or even on my tiny sofa CD.

I have not found it yet, in fact I cant find it anywere at all.

[root@localhost]# rpm -qa | grep cyrus-sasl
cyrus-sasl-sql-2.1.19-3ts
cyrus-sasl-2.1.19-3ts
cyrus-sasl-ntlm-2.1.19-3ts
cyrus-sasl-md5-2.1.19-3ts
cyrus-sasl-plain-2.1.19-3ts
cyrus-sasl-devel-2.1.19-3ts
cyrus-sasl-gssapi-2.1.19-3ts

also the tutorial is way out of date like 2004 and thats probley half my problem.
