passwd mismatch

[Mike Ponto]

I have been trying to follow the "instructions" at 
"http://blog.iandreev.com/?p=1975#dovecot" and they seem to be pretty 
good.  everything works until I get to the part were I test the dovecot 
installation and it keeps failing.
I get an AUTH fail error at the "telnet localhost 110" login commands

I am trying to setup 3 domains:
domain1.us
domain2.com
domain3.com
I have 4 users entered in the /etc/dovecot/users file
I followed the instructions for creating an encrypted password but don't 
think it is correct and I don't have the knowledge to say why.  Just 
doesn't feel right.

I admit I am over my head and the learning curve just got exponential - 
any help at all would be really appreciated.
