Hy
Since last update, it's impossible to receive mails on my system :
This is the mail system at host smtp.alternatiq.com.
I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.
If you do so, please include this problem report. You can
delete your own text from the attached returned message.
The mail system
<user@netmusic-city.com>: host smtp.netmusic-city.com[82.235.53.249] said:
550 relaying denied user@netmusic-city.com (in reply to RCPT TO command)
If a active the "unknown user mail reception rule" with postmaster for example it's working, but if i deactivate this option i had this 550 user error.
Somebody have an idea ?
