    Have you received the following error from a Time Warner mail server?

    Remote host said: 421 4.7.1 - Connection refused - <> - Too many concurrent connections from source IP

    Time Warner defaults to allowing a maximum of 10 concurrent connections from an IP address.

    If you are a high volume mail server you can contact Time Warner and request that they consider raising the limit for your mail server.

    Regular mail server admins will want to make sure that they only open at most 10 connections to rr.com domains at a time.
