The most likely source of this type of issue is that the message security service always checks the DNS MX entries for a machine https://kb.iu.edu/d/beha name before delivery and routes mail to the highest priority MX record. Depending on DNS configuration, this could cause the security service to deliver to its own servers.

RFC 821 requires that a SMTP server do an MX record lookup a domain before delivery, and since that MX record points to message security servers, the message will be delivered from the message security service directly back to the service. To correct this, do one of the following: Remove the MX entries for mail.mydomain.com. Entries should already exist for mydomain.com pointing to the mess
