I configured a Postfix Server on RHEL 5

this is how my main.cf looks like

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
broken_sasl_auth_clients = yes
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix

manpage_directory = /usr/share/man
mydestination = $mydomain, $myhostname, localhost.$mydomain

smtpd_tls_session_cache_timeout = 3600s
smtpd_use_tls = yes

i have used dovecot and cyrus-sasl for smtp-auth to prevent open relay
i have also configured postgrey and Mail Scanner..

when i telnet to my server on port 25 output comes

Trying 127.0.0.1...
Connected to mail.domain.com (127.0.0.1).
Escape character is '^]'.

Can you check that the output of
and
match the domain that you own? They must. And your DNS records with your registrar need to be uptodate before mail will function correctly. Your conf file looks fine, at a glance.

hostname comes with mail.domain.com

seems perfect..

and for a delivery in local domain.. there shudnt be any requirements for DNS... where as DNS is also working fine..

here is the output of postqueue -p if it helps

P.S. my users are on LDAP and it is working fine.. i have binded LDAP with pam mechanism using authconfig.

looking over your config i noticed that you don't have a "mynetworks = ...."
i see the "mynetworks_style = host"

i would add "mynetworks = 127.0.0.0/8" and then restart and try.
one more thing that i would add is "relayhost = ", leave the trailing area blank. this makes it so that noone can relay through you. if you have your dovecot, authentication, set up properly then it will check for the user trying to log in and send their mail without complaint.

cheers

Just checking again, have you setup DNS correctly for your domain?
