Dovecot, postfix pop3/imap server issue

[Konduktorn]

Hi

I'm having a problem setting up Dovecot:

The command

#telnet user smtp

returns:
user/smtp: Temporary failure in name resolution.

Does this mean that there is a problem in the aliases file? (/etc/aliases)

#telnet localhost smtp

, works fine...

Here is the configuration!

postconf -n returns:

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
debug_peer_level = 2
home_mailbox = Maildir/
html_directory = no
inet_interfaces = all
mail_owner = postfix
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mynetworks = 127.0.0.0/8
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES
sample_directory = /usr/share/doc/postfix-2.3.3/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination
smtpd_sasl_auth_enable = yes
smtpd_sasl_path = private/auth
smtpd_sasl_type = dovecot
unknown_local_recipient_reject_code = 550

Dovecot -n returns:

Please be gentle with responses, I'm a newbie regarding Linux and mail servers =)

i think you are getting things mixed up.

if you tell it

telnet user smtp

it is going to try to resolve "user" as a computer name, which will most than likely fail. it queries the services file to find out what port = smtp.

localhost works, because it is defined in the /etc/host file.

the /etc/aliases files only pertains to users, not computers

AAh, okay. Yeah, that makes sense.

What would you recommend me to do, in order to test smtp?
