Last week we found out that Helpscout sends email from AWS servers. Thank you, Helpscout, for forcing me to lift the AWS blocks on my incoming MTAs, that were cutting down my incoming spam scanning load by a factor of two. At least. Note that I work for an email hosting company, which makes this infinitely more annoying. A factor of two, in this case, is a non-trivial number. --lyndon
