    In my mail log, I have found a lot of this error, but I cannot figure out what it is -- no one online seems to have ever encountered it:

    host vip-us-br-mx.terra.com[] refused to talk to me: 421 4.3.2 rejected: Too much dconnections from mail.server.com[my IP address]

    You should check if your server is maybe abused by spammers that try to connect to vip-us-br-mx.terra.com.

    Please test if your server is an open relay: http://www.spamhelp.org/shopenrelay/
