Kind of stumped here. How long does it take for a mail server such as Yahoo, Hotmail, or Gmail to attempt mail delivery to secondary MX Records?
I have set up a backup exchange server for my my domain. I have tested it using telnet and mail flows perfectly. I have used Wormly
to test mail directly to the secondary server, and success! I have my MX setup like this:
mail.domain.com priority 5
mail2.domain.com priority 10
I felt confident that if my Primary server went down, the secondary would collect the mail until the primary came back on line and requested the mail from the secondary (SMTP Connector). So I decided to test it. I shut down my primary mail server and started sending emails. I sent them from all the previously mentioned servers and nothing..... I waited 2 hours and the mail still did not reach the secondary server. I did not receive any NDR's. What am I missing here?
Thanks is advance
