A user recently got an email from DH that said:
firstname.lastname@example.org: host AIL.pipinc.com[126.96.36.199] said: 557 Your IP address is from a blacklisted country. Disconnecting… (in reply to end of DATA command)
Has anyone seen this? What can be done?
I checked a couple of blacklist sites but the DH mailservers 188.8.131.52/1 were not listed.
