Thanks. I know I heared somewhere that one of these "measures" can "hurt" because of resulting in the domains being blacklisted faster. I hear a lot of thing but do any of you have input on that?
I'd have to do some digging, but I can't see how having these how work against you. Most, of these are requirements to send to isp's in an effort to be transparent, so that they accept your mail. I can see how you might get flagged if some of the info didn't match. Regardless, if you're sending GI at a colossal rate, then getting blacklisted is inevitable.
