But of course our percentage is going to go up.
Our company has two diverse ISP's with two diverse T1's to the internet. We have redundant MX records to support this (stsconsultants.com) .
However, if our primary ISP goes down, our e-mail is re-directed out our backup connection which is the IP that has been BL'd (65.88.34.229). Of course we are going to have a huge percentage increase in e-mail! That IP doesn't see ANY email unless we are in a failover state which happened recently.
Why should we be punished for having a redundant connection?
