qmail aliases like "melanie.desaive"

[Melanie Desaive]

hello,

I tried to set up qmail aliases via .qmail-alias and it worked well 
with single names.
But all aliases like .qmail-melanie.desaive etc. did not work.
I tried to escape the dot with \ # "" but nothing worked.
I did not find anything about this problem in the qmail documentations.

If someone knows how to create such aliases, please let me know.

greetings,

Melanie
