Is there a list of the most common email validator blacklist reasons and what they mean?
I'm looking for a list of all (or at least the most common) reasons that cause an email to be blacklisted. Some are self explanatory, but I seem to have run into a few lately that need some translating. I want to make sure I'm not just removing them from the blacklist to have them be put back on immediately the next time we attempt to email them.
