Hi,
I have one of our users who is unable to send an email to one of his
clients. His messages get returned with this message:
Final-Recipient: rfc822;
stevek@teraco.com
Action: failed
Status: 5.0.0
Diagnostic-code smtp; Site
teraco.com (12.12.240.139) said
after data sent: 550 5.7.1 Please send this email to your IT
personnel. 550-5.7.1 We are rejecting your email, because you were
found on
zen.spamhaus.org
spam black list.
His email takes the form of
authorized_user@ehowe.com
I checked
spamhaus.org and the IP address of
ehowe.com is not being
blacklisted. What is in their blacklist is his personal IP of the
machine that he is sending the email from. It says 74.136.165.243 is
listed in the PBL, in the following records:
PBL1548045
This is why I can send an email to his client from an
ehowe.com
email address and he can't.
Shouldn't his client's
mail server (
teraco.com) be checking that the
message it is receiving is from our e
mail server given the address
isHIDDEN@ef="http://ehowe.com">ehowe.com and then checking the IP for
ehowe.com to make sure
it's not blacklisted?
He tried to remove his IP address, which is assigned from his
service provider, from the blacklist but
spamhaus.org gave him this
reply:
Removal of IP addresses within this range from
the PBL is not allowed by the netblock owner's policy.
Is there anything we can do here or is it all on his clients email
server.
