[Mailman-Users] Variables in welcome message are not replaced

[Stefan Burkard]

Hi all
I set up a mailman mailinglist (everything preinstalled on a plesk-based
hosting) and have a strange effect.

When I subscribe a user from my address by using the email-command with the
optional "address=<user-address>", the user receives the
confirmation-message without problems. BUT if the user replies to the
message (to confirm), he gets a welcome-message with the variable-codes
instead of the real values.

When the user himself does the same procedure (obviously without the
address= option, that is not needed in this case), the welcome-message looks
just fine.

I tried the same with the mailman-users-list itself and it worked, so I
think this is not a bug - at least not in the actual version. I am using
version 2.1.5.

Can anybody help me with this one?
Regards
Stefan
