this is first time I set up a server from scratch and I consider myself a fast and good learner for new stuff, so I did my best to setup postfix with dovecot in CENTOS 6, so I'm getting relay access denied on my maillog:
warning: 187.167.4.199: hostname 187-167-4-199.static.axtel.net verification failed: Name or service not known

I'm able to read my emails but I can't send email to anyone outside, can anyone take a quick look?
Best Answer
The default value not altered.
smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination
You are not sending from
$mynetworks
.You are not sending to
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
.Perhaps you want:
Modify cert values to be appropriate.
Setting up sasl is too variable to describe here, but http://www.postfix.org/SASL_README.html#server_dovecot should be a good start.
