    I want to fix a few mistakes within the Mail records which include warnings and errors, because I think that mail might be bouncing back because of it.

    I currently am not sure if this would help, but here is a log:

    This message was created automatically by mail delivery software.
      A message that you sent could not be delivered to one or more of its
      recipients. This is a permanent error. The following address(es) failed:
          SMTP error from remote mail server after RCPT TO ***@***.com>:

    A few things to check


    This looks like a "sender verify fail". If this is a bounce from someone on your server
    trying to send to another domain, that other domain's server has "sender verify" enabled in
    their exim config. (or other MTA)

    Two things to check: 1) Does your domain have an MX record pointing to your mail server, on your DNS provider (domain registrar, usually) "A" record for your domain?

    2) Some mail servers are configured to check rDNS (aol, for one). If your server has no rDNS entry, all emails sent to such servers will be bounced.

    To my knowledge, only your datacenter can do the rDNS. Just tell them the IP and domain name of your server, they will create the rDNS record.

    Good luck.

    It seems we do have an DNSr record, and I believe we have an A record as well. Any other ideas?
