hello I get quite often burst of Mail Delivery error messages, hundreds in a minute or two like the one below, addressed to «myhostname».localdomain. Then it stops by itself and restarts a couple of days later.
Weird is the line: Received-From-MTA: DNS; localhost Any idea from where this comes from? and how to prevent this? Thank you and best regards _⌢_ Meaulnes Legler '¿') Zurich, Switzerland. `-´ +41¦0 44 260-1660 fax:-1661 ——begin——————————————————————————————————————————————————————————————— The original message was received at Mon, 1 Jul 2019 05:00:21 +0200 from localhost with id x6130LRY022291 ----- The following addresses had permanent fatal errors ----- <mailman-bounces@bleue.localdomain> (reason: 550 Host unknown) ----- Transcript of session follows ----- 550 5.1.2 <mailman-bounces@bleue.localdomain>...
