Deliver problem

[mailing at scastagnoli.info]

Hello everyone!
I'm using Cyrus since last summer and I've been able to solve all my problems 
(with help from this mailing list ;-) ) but now I cannot solve the following.
I use SuSE professionale 9.2 and I run cyrus without problem, I can connect 
with 

telnet localhost imap 

and authenticate with 

0a100 login test test

Also I can read my mailbox from Evolution but when I try to use deliver 
command in the form of the book "Managing IMAP" 

deliver -m user.test test < mail

nothing happens.
I've looked in some log files: 

/var/log/messsages
/var/log/mail.info

but I can't see anything about errors in communication between deliver and 
imapd.
Please, can someone help me?

Thank you so much!!!

Stefano
