TwitterMy clients are getting errors as this " 451 http://www.spamhaus.org/query/bl?ip=xx.xx.xx.xx " while sending email but i am not.
When i check deeply i realize that my client ip addresses in pbl and i do not understand why the qmail is rejecting clients.
SMTP Auth. is activated on plesk and also they are selecting my server requires authentication while setup mail client.
so what should be the problem ?
I am using plesk 10.x
