POSTFIX bouncing when destination is my domain

  • 772

I am using provider mail hosting to send emails. On my Webserver I also have Postfix running and configured. Here is my main.cf

smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
append_dot_mydomain = yes
readme_directory = no
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
myhostname = 2-5-8.bih.net.ba
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = bhcom.info, 2-5-8.bih.net.ba, localhost.bih.net.ba, localhost
relayhost = 
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = 
mailbox_size_limit = 10485760
recipient_delimiter = +
inet_interfaces = 80.65.85.114

When I try sending email to my hosted domain name, every message gets bounced with this error:

However, when I try to @gmail.com, it sends message without problems, and here is log. What might be the issue?

    Well, the log says it:

    Nov  4 20:38:34 2-5-8 postfix/local[990]: 1492A3E0C6C: to=<[email protected]>, relay=local, delay=0.12, delays=0.08/0.01/0/0.04, dsn=5.1.1, status=bounced (unknown user: "info")
Nov  4 20:38:34 2-5-8 postfix/local[990]: 28ED53E0C6D: to=<[email protected]>, relay=local, delay=0.06, delays=0.03/0/0/0.02, dsn=5.1.1, status=bounced (unknown user: "razvoj")

    You have no local user info and no razvoj the local delivery could deliver mail to. If I understood your post correctly, you do want to send mail from that machine, but this is not your mail server where you want to receive and read it, right?

    If it's correct, just drop bhcom.info from mydestination and everything should be fine.

    A bit of background: every hostname listed in mydestination is considered local by Postfix and then itr tries to deliver the mail to that local user, which in your case does not exists.

  2. Also make sure you have all the packages needed. I had relayhost all set up properly in main.cf, but was getting relay=none until I did this (on Ubuntu 14.04):

    apt-get install mailutils libsasl2-2 ca-certificates libsasl2-modules

    Not sure why this fixed it. The above came from a postfix relaying HOWTO at easyengine.io.
