[IMail Forum] 2 MX records

[Schmeits, Roger]

Greetings: We are in the process of trying to routing all mail to a new smtp gateway. I am getting lost in some of DNS issues and need clarification.   In the past we have always routed mail to host mail.clarksoncollege.edu at 65.174.229.137 with a  weight of 10. As of Saturday I created a new entry in sprint's DNS servers called mail2.clarksoncollege.edu with an IP of 65.174.229.141 weight of 5.     Sprint uploaded the append/new zone files on the Dec 18 at Midnight. If the TTL is set for 12 hours on mail.clarksoncollege.edu we should be seeing multiple entries MX entries for Clarkson. But I am not.   I am unclear to exactly what the TTL  is on the mx records is -- I keep seeing different values. I ran some tests Friday and I think it is 12 hours.     Can someone steer me in the right direction? Thanks.     ########################## Roger Schmeits Sr. Network Engineer Clarkson College http://www.clarksoncollege.edu (402) 552-2542 ########################## Disclaimer: The information contained in this e-mail is privileged and confidential and is intended only for the use of the addressee(s) indicated above.
