e-mail messages undelivered, or delivered to "bulk mail" or "junk" folders

Level 2

Recently I have found that e-mail messages sent via have not been delivered or are sent to recipients' bulk mail or junk mail folders.

In the case of the undelivered e-mail, I received the following message:

The following message to ... was undeliverable.
The reason for the problem:
5.4.7 - Delivery expired (message too old) 550-'5.7.1 Connection refused. is blacklisted in Invaluement RBL List. See'
Reporting-MTA: dns;


What is the problem here, and how can I get it fixed?
