Postfix issue: Relay access denied and problem with sending mails

[Debianer]

Hi,
I've just installed postfix and popa3d - debian packages.

1. When I try to send an e-mail from Gmail account to me:

user@domain.com

I'm getting error:

Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 5.7.1 <user@domain.com>: Relay access denied (state 14).

2. When I try to send an e-mail from Postfix to Gmail it normally, go out, but I am not getting this e-mail on my Gmail account.

My main.cf is:

myorigin = /etc/mailname # domain.com

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

append_dot_mydomain = no

readme_directory = no


smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

myhostname = my computer static ISP hostname
mydomain = domain.com
mydestination = $myhostname
mynetworks = 192.168.0.0/24
inet_interfaces = all

alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases

disable_dns_lookups = yes

mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +

What should I do?

Please check if your MX record is ok...

dig mx yourdomain.com

... and that your server isn't blacklisted: http://mxtoolbox.com/blacklists.aspx

MX Record is my server IP.

Blacklist check:

Checking 78.88.117.27 against 123 known blacklists...
Listed: 2 time(s)
Timeouts:7

The MX record must point to a hostname (e.g. mail.example.com) which then points to an IP (using an A record).

Is your server hosted on a dynamic IP and/or was it abused by spammers?

My server is hosted on static IP and it was not abused by spammers.
Fixed MX record. Now it points to hostname, which points to server IP.
... but still e-mails from Gmail cannot be sent, beacuse there is same error with Relay Access Denied.

Checked log when sending an e-mail to Gmail and other mail server. Most servers (maybe all) say that I am spammer.

I am not sure is it spam block or becuase I dont have revDNS configured properly for my domain.
Found somewhere that configuring revDNS helped for this problem.


Now have problem with configuring bind9. Installed it then

Added to named.conf, my IP is 73.48.217.17

zone "17.217.48.73.in-addr.arpa" {
type master;
file "/etc/bind/17.217.48.73.in-addr.arpa";
};

17.217.48.73.in-addr.arpa - file

17.217.48.73.in-addr.arpa.    IN PTR  domain.com.

I am not Primary DNS for domain.com, it has external default DNS servers.

I've checked the RevDNS and its still not correct. Here: remote.12dt.com/lookup.php

What should be inside of 17.217.48.73.in-addr.arpa file?
I've only one line of code as you see.

IT can take up to 72 hours until DNS changes propagate, so you might have to wait a little bit longer.

Please contact the maintainers of the blacklists and ask them to remove your server.

A PTR record is important, but it must be created by your ISP/hoster (the one who gave you the IP address).

Also make sure you have SPF records for your domains.
