Debian's mailing list server rejected my mail:

I've consulted my mail server admin and he said:

"(Debian mailing list's) Postfix does a strange and broken thing, and
it does sender verification callouts (to check that an address exists)
using a non-empty sender. I've seen this before, but usually it uses
"postmaster@" as the address, so I have a special hack to accept mail
from postmaster@ to the signed addresses. I've now added another hack
to accept mail from double-bounce@ too, which is what lists.debian.org
is doing -- but it would be much better if they'd fix their callouts
to use the _empty_ sender as they should."

Thank you.

Hi,
This is not debian postfix special. In fact its postix default [1].
But we are currently discussion if we should change the default.
