Chosen solution

So your sending server is blocked from sending mail to that server. Contact your provider with the exact error message and they will have to do something about having the IP address removed from the blocklist.

A server can be blocklisted because some user of the server is sending spam, or it could be because you are sending spam. Exactly how you get on with your mail provider will depend on the cause of the listing.
