I was sure that none of the involved MTAs that I have control
over did something like that. But when I was digging into it,
I found that all mails were addressed to listname at main-fqdn
although had been sent to listname at some-other-fqdn. This
happens when the other fqdn is not a "real" DNS-entry, but a
In addition to that, Mailman seems to have the feature to
get/set the hostname from the string following the @-sign in
the original mail's To:-header.
These two factors caused me to think Mailman was doing
something weird. The mails' look could be changed by adding
explicit DNS-entries for the server's additional names.
