More and more companies are getting caught up in our blacklist filter because one or more of the blacklists(spamcop, etc.) have caught a hosting services' particular email server and placed it on their blacklist.
It is terribly frustrating to have 10 emails coming from a legitimate client and 2 emails get blocked because they happened to get sent from server142.hosting.com (blacklisted) where as the other 8 went through server143.hosting.com (which is not blacklisted.)
I can't keep telling clients to get reliable and responsible email providers otherwise I won't have any clients left! :-)
Is there a way to have an email domain pass through even though the sending server has been blacklisted? I literally have a dozen or so domains where this happens regularly.
