Good point....
I can see 5 files in the directory:
list:member:generic:footer.txt
list:member:regular:footer
list:user:notice:welcome
list:user:notice:welcome.bk
list:user:notice:welcome.txt
"list:user:notice:welcome.bk" has the wrong welcome message. (I renamed it to back it up before correcting the welcome message) "list:user:notice:welcome" and "list:user:notice:welcome.txt" has the identical correct welcome message.
I removed "list:user:notice:welcome.bk".
Now I have:
-rwxr--r-- 1 list list 0 Oct 10 2018 list:member:generic:footer.txt* -rwxr--r-- 1 list list 0 Mar 30 2021 list:member:regular:footer* -rwxr--r-- 1 list list 507 Jan 9 01:35 list:user:notice:welcome* -rwxr--r-- 1 list list 506 Jan 15 04:45 list:user:notice:welcome.txt*
I restarted mailman3.service, mailman3-web and nginx.service.
Tested and issue still persisted....
Thank you for your help!
