How to contact moderator(s)?

Hi, my post made on July 7 to the printers forum was rejected by moderators as I was informed this morning (July 11) via email.


No reason was  given or info given on how to contact moderators.


When I replied to rejection email notification it said email could not be delivered.


How do I contact moderators so I can fix the post so it can show in the forum?
