Hi Brad, I can empathize with the issues you're having as optonline.net addresses are not accepting our mail as well. We're seeing: 451 4.7.1 Resources restricted for host [IP] - try again later - H5,5 - 13
Unfortunately, we've (an ESP) not had any success either in our attempts to resolve the issue. We've cut our sending rates down to a crawl with zero luck. Overall volume we're attempting to send is low and spot checking our senders (shared IPs) everything appears to be clean. Searching through mailop and it appears there's not been any replies to contact being made off list. If there is, I could use some assistance in resolving this as well. Appreciate your time.
