Many of our customers got a ton of spam on Saturday (you might not be checking it until Monday, but most of it came on Saturday). This was our fault. We made a change to our IP addressing in our mx2.emailsrvr.com network, and this temporarily caused all mail that arrived to the mx2 servers to get white-listed—even spam.
This problem was identified and corrected on Sunday morning.
If you were an affected user, please accept our apologies. We have modified our white-listing logic so that this mistake cannot be made again in the future.
At the very least, hopefully you can see how much spam we really are blocking on a daily basis.
