Karouri, if someone wants to do this in purpose, he will do it from an 
Internet Cafe not from his home of course.

my point is just to run a test but haven't done it in a responsible way. 
Sorry.

and sasl auth is a must nowadays. Something like:

# server
smtpd_sasl_auth_enable = yes
smtpd_sasl_local_domain = $myhostname
smtpd_recipient_restrictions = permit_mynetworks,
  permit_sasl_authenticated, check_relay_domains
smtpd_sasl_security_options = noanonymous

should do the job.

karouri, I need help in configuring my email server for the purpose of 
learning. I installed cyrus-imap and postfix.

I tried to add lines such as these but failed

mailbox_transport = "lmtp:unix:/var/lib/imap/socket/lmtp"
mailbox_transport = cyrus
home_mailbox = .Maildir/
mailbox_transport = lmtp:unix:/var/lib/imap/socket/lmtp
local_transport = cyrus

My postfix works. My imap server works. The problem is how can I convince 
postfix to deliver the messages to /var/spo	ol/imap/[a-z]/ depending on the 
sender. It seems cyrus-imap needs the messages to be here.

I intentionally put the question here so may be Arabeyes admins loves to share 
an opinion. Otherwise, I will make it private.
