This is fine if your server serves email to just you. But when a customer or a executive doesn’t get his email from Amazon or Google, you don’t get to say “They are not following the RFCs.” > E-Mail is not real time communication by design ! You’re living in the 90s. If someone is expecting an email and it’s delayed by 5 minutes I hear about it. Greylisting large companies like Google, Yahoo, Amazon, Apple, etc is *stupid*. -- Carlin's Third Commandment: Thou shall keep thy religion to thyself.
