The reverse is also true -- I've seen a noticeable uptick in gmail-originating spam hitting my servers. Currently my software is configured to keep anything originating from google.com whitelisted, but it's getting a little obnoxious and I might have to reconsider. One of the more annoying nuisances hitting me personally is from a YC startup, Zenefits. I really dislike them and their moronic hey-buddy spam and that I can't reasonably blackhole the originating network for a while.
