[Mailman-Users] GID (cont.) --> hostname

[[NIP] Bram]

Hi!

I solved the GID problem. I completely started over from scratch and now
it works. But still one problem, well, two actually:

I have Apache configured to use http://mailman.domain.tld, but Mailman
still thinks it's on http://dell.domain.tld. How can I let Mailman know
that it's accessable at mailman.domain.tld?

Same problem for the mails: it sends mails ... at dell.domain.tld, instead
of plain ... at domain.tld. Here too: how can I let Mailman know what
hostname to use?

Big thanks!

Bram
