    Most of the time my email works for both incoming and outgoing. However, occassionally I will receive the following message...

    Note: I have already created an A record and MX record with my host for both greatgolfswing.com and server1.greatgolfswing.com

    Can anyone explain why I occasionally get these messages?
    Thanks in advance!

    You must not use an IP address in an MX record. Use an A record instead. Have a look here: http://www.howtoforge.com/traditional_dns_howto
