On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

Question

How to enable Postfix debug mode?

Answer

It can be done by either one of the following processes:

Click on a section to expand

Via postconf utility

  1. Login to the server over SSH

  2. Execute the following (specifying the required IP addresses and/or recipient domain names to monitor instead '203.0.113.2' and 'example.com'):

    # postconf debug_peer_level=4

    # postconf debug_peer_list=203.0.113.2,example.com

    Note: No spaces between values in debug_peer_list are allowed.

    To disable debug, run:

    # postconf debug_peer_list=""

Editting the master.cf file

  1. Edit the /etc/postfix/master.cf config file, add -v right after "smtpd" in the file, like the following:

    CONFIG_TEXT: smtp inet n - n - - smtpd -v

  2. Apply the new settings:

    # service postfix restart
