The SMTP Server program
firstname.lastname@example.org: host leanabh.scotnet.co.uk[220.127.116.11] said: 550 5.7.1 Email rejected as sender is blacklisted by www.spamcop.net (in reply to MAIL FROM command)
I'm clueless about how to remove our email from the blacklist. And we conduct much of our small business via email, and are very concerned.
Is the dreamhost.com mail server blacklisted? Or is my email being used to spam? I'd appreciate if anyone can help me out with this.
Thanks in advance,
