[horde] bug? unsubscribe from list

[Dietrich, Thomas (TU Ilmenau)]

Hello,
this is something like a meta-bugreport :)

I wanted to unsubrscribe from this list. I wrote to
"horde-unsubscribe at lists.horde.org" three times and got a confirmation
each time. I'm still receiving the mails for this list. Please check
your system and unsubscribe my mailaddress from the list.

Thanks and all the best,
Thomas
