I have been trying for weeks to get in touch with someone who will respond with something other than a form letter at Verizon. Can someone please contact me off-list? My company (Modwest) is being unilaterally blocked. I can't even send mail to abuse, postmaster, etc. from an @modwest.com address because of the block in place without a reason and without recourse.
Welcome to the club! I'm sure someone will get back to you shortly. But in the meantime, I can share my experience with this, and perhaps get some opinions on how wise their "anti-spam" measures are. VZ was unable to tell me why we were initially blocked, but we were for a number of days. Not at the IP level, but at the envelope level; meaning that if you issued a "mail from:" with the domain in question, you'd get the "550 You are not allowed to send mail:sc004pub.verizon.net" message. To this day, we still see some refusals from them like this in our logs. What I imagine is happening is that the check they do (connect back to your mx and try to verify the address exists) times out occasionally, either due to mail server load or connectivity issues. This causes your mail to them to bounce with a permanent error. Not really the best way to handle mail, but I digress. Looking at your mxer, I see that the "rcpt to:" is a bit slow. I wouldn't be totally shocked if this had something to do with your problem... Charles
TIA, and I'm sorry for posting here but it's really my last resort (as it should be anyones IMHO).
