Hi, Hi, i tried now with a Postfix 3.x -> Mailman Postfix has en extremely useful setting called debug_peer_list where you can list addresses of machines whose messages you are interested in and the level of detail can be set with debug_peer_level. this will result on very detailed logging of the SMTP conversation.

Original to Mailman: https://pastebin.com/c4BHeEkJ Subject: =?utf-8?q?=5BJaninsliste=5D_=5BSAV- LINUX=5D_Notice_from_Sophos_Anti-Virus_on_server=2Eexample=2Ecom?= After Recieving: https://pastebin.com/JG0NKbjq Subject: =?utf-8?q?=5BJaninsliste=5D_=5BSAV- LINUX=5D_Notice_from_Sophos_Anti-Virus_on_server=2Eexample=2Ecom?= Both of then show the same Subject: header.
In https://pastebin.com/c4BHeEkJ, Line 79+80 it says
Subject: [SAV-LINUX] Notice from Sophos Anti-Virus on server.example.com [DEMO1]
So this correct.
in https://pastebin.com/JG0NKbjq, Line 177 its truncated
Subject: =?utf-8?q?=5BJaninsliste=5D_=5BSAV-LINUX=5D_Notice_from_Sophos_Anti-Virus_on_server=2Eexample=2Ecom?=
So my guess is, that the local Postfix on the Mailman Server is doing the QP. In the Chain there are
postfix 3.x -> MS Exchange -> Postfix 2.x -> Mailman
After Releasing the mail from hold Mailman -> Postfix 2.x -> Exchange
