I don't think you read or understood what I wrote. You were not routing through a smart host (third party SMTP relay.) This is your problem. There is a specific reason I recommend doing so: the reputation of the sending IP address almost always overrides the reputation of the sending domain. A smart host operated by a third party, such as Google: https://support.google.com/a/answer/2956491?hl=en https://support.google.com/a/answer/2956491?hl=en , would have solved your blackholing issues because it's the third party's job to maintain extremely good reputation of their IPs sending mail. Most importantly, they have high volume of legit emails, and volume is key to maintain good reputation. Finally, even if you have a low-volume domain, your emails will benefit of the good rep of the smart host, and thus would not be blackholed. I will repeat it again: if you host your mail server, you definitely should also use a smart host, and all the spam/blackholing issues disappear.

Using Gmail as a smart host defeats the point as mentioned in the root comment of this thread: Google can read your email. Google also rewrites the "From:" address to your Google account's address, unless you jump through some hoops to add it to your account. This has become more difficult recently, and needs to be done for every address (which is an issue if you use single-purpose email addresses).

  «Using Gmail as a smart host defeats the point as mentioned in the root comment of this thread: Google can read your email.» Many things wrong with this sentence: • Don't like Google? Then use any of the hundreds of other smart host relays: Sendgrid, OutboundSMTP, etc • The smart host can't read your incoming mail (typically more sensitive than outgoing.) • Google, being a mail provider, can usually read your email anyway, because all your conversations with Gmail users end up in Google's hands. «Google also rewrites the "From:"» Google has multiple smart hosts offerings, but the one I linked to does NOT rewrite the From:.
