What are the exact rejection messages? What are the exact emails? Is this an ISP that pushes end user blocks out to the MTA (which some do)? Is this an ISP that does content filtering before accepting the mail? How often is this happening? I've seen cases recently where ISPs fall over and 5xx all mail for a few hours because of a config problem at their end. If you want to drop me an email with details I'll see if I can give you some better answers. That’s a much more complex question than you may think. What are the exact rejection messages?

I'd love to prod a bit more into this. What about inconsistent bouncing results? Same-ish email, same IPs, sending to the same addresses, but sometimes they hard bounce, and sometimes they don't. How does one get control over this seemingly uncontrollable server behavior? Hey Laura – love it, thanks for this post!
