Question

Configure postfix to send e-mails to others.

  • Posted July 12, 2014

Following this tutorial i have successfully installed Postfix on my server, but for some reason, i cannot send e-mails from other servers. I can send e-mails to other users inside my server like user@mysite.com, and i can also receive e-mails from Gmail, and Hotmail, but when i try to send e-mail to those sites, nothing happens. Do i need any extra configuration on Postfix to be able to send e-mails to others?

Looking in the /var/log/mail.log i found this:
