It is a true bounce - mail is being rejected.  The error message is phrased as a "temporary failure," but the message is bounced at the SMTP transaction.  “At some point,” they stop bouncing.  RR won’t say when that happens.


<user at roadrunner.com>: delivery temporarily suspended: host

I will probably turn that on soon - it is available to me.

On this instance, they haven’t been very helpful.  For the most part, though, they have been decent.  The largest of my lists that I admin has over 7600 subscribers, with about 15 emails going out daily - that’s about 115K total emails a day, and for the price I am paying DH, I haven’t found anywhere near a better deal.  So I accept these (occasional) issues along with the deal I’m getting.
