What the hell am I doing wrong that I can not send mail to any @debian.org address?
SMTP error from remote mail server after end of data: host master.debian.org [126.96.36.199]: 550 Administrative prohibition
None of SMTP servers I used is blacklisted and I haven't seen problem
with any other recipient than master.debian.org. Anyway it would be
great if I would know what this
Administrative prohibition means.
After googling I found out that it might be something bad in my headers,
but nothing what would tell me how to fix it...
