CentOS5 Vserver mailing setup - sasl problems

[vargadanis]

Hi all

I don't think I have posted a lot here. I am quite new to this whole server thingy. I would like to follow the steps of this tutorial:
http://howtoforge.com/virtual-users-and-domains-postfix-courier-mysql-centos5.1-p2
I linked the 2nd page because I suppose the problem I have is in connection with the sasl daemon.
When I try to telnet to postfix (telnet localhost 25) I get a message that connection closed by foreign host. In the syslog (which is only partial due to the vserver) has these lines:

bash-3.1#


Any idea why this could be?

The sollution was quite simple yet very confusing. After reading a post on these forums I installed a single package which has solved this problem.
yum install cyrus-sasl-plain
The end of the story... Good luck everyone!
