this is all pretty correct.

"euve51864.serverprofi24.de" is the natural name of the vServer, I am
running.
I don't have a real domain configured, since I mainly just use it for
mailman.
I configured all Mailman lists to use something like <list name>@rc-worms.de,
where <rc-worms.de> is the www domain of my sports club, whose
administrator I am.
For better readability I named and configured all lists this way, to use <
members at rc-worms.de>, <team1 at rc-worms.de> as exlicity reply-to address and
so on.

This worked pretty well for years.
Did it now turn into a problem, that reply-to address and domain () bear a
different IP/rDNS result?
Is there something you could suggest in this case?

Should I maybe configure a subdomain on my vServer, like <lists.rc-worms.de>,
from which the mails will be send from and can bear own DNS config?

Kind regards,
Sascha.
