Hello Mark,
thanks for your hint.
Postfix is runnig as mta on my machine.
I tested port 25 with swaks ->mail to user on server: localhost port 25 -> everything fine
Mailman is configured with localhost for incoming and outgoing mails.
After stopping mailman3, deleting all files in the queue directories, restart mailman3 I sent a test-mail
/var/log/mailman3/mailman.log Apr 07 12:08:23 2020 (28198) Master started Apr 07 12:08:24 2020 (28206) out runner started. Apr 07 12:08:24 2020 (28202) command runner started.

I have no idea what to do for solving my problems.
Regards from Hamburg
Wolfgang

Thank you Steven for your reply!
I Set smtp_server to port 25 and got a "Cannot connect ro SMTP Server on port 25", the former error message didn't show again.
As I see port 25 is reseved for postfix. So I have to fiddle out how mailman3 could also use this port for sending mails out. ....
You need an MTA for Mailman to deliver its mail to. Normally this will be Postfix, sendmail, Exim, etc running on localhost and listening on port 25.
Do you have such an MTA running on localhost?
Note, Mailman does not directly send mail to end recipients. It only delivers mail to an outgoing MTA.
