mx记录优先级相同的话,邮件发哪里

One technique used to distribute the load of incoming mail over an array of servers is to return the same preference number for each server in the set. When determining which server of equal preference to send mail to, "the sender-SMTP MUST randomize them to spread the load across multiple mail exchangers for a specific organization", unless there is a clear reason to favor one

More than one mail exchanger may share the same preference value, too, giving the mailer its choice of which to send to first.

The newest version of sendmail, Version 8, will actually choose randomly among mail exchangers with the same preference.
