Hello. Are you by any chance seeing this message? Jul 9 08:43:06 mail postfix/smtp[18059]: C95E4849A: to=*, relay=gmail-smtp-in.l.google.com[2607:f8b0:400d:c0b::1b]:25, delay=1.3, delays=0.29/0.04/0.53/0.46, dsn=5.7.1, status=bounced (host gmail-smtp-in.l.google.com[2607:f8b0:400d:c0b::1b] said: 550-5.7.1 [2001:19f0:5:752:f000:: 1] Our system has detected an unusual 550-5.7.1 rate of unsolicited mail originating from your IP address. To protect 550-5.7.1 our users from spam, mail sent from your IP address has been blocked. 550-5.7.1 Please visit 550-5.7.1 https://support.google.com/mail/?p=UnsolicitedIPError to review our 550 5.7.1 Bulk Email Senders Guidelines. j64si7748761qte.160 - gsmtp (in reply to end of DATA command)) If so... You might want to try going through the sender guidelines page. I'm running a clean MTA on a fresh IPv6 address, with correct reverse DNS, correct SPF, etc, etc. I've never sent or relayed unsolicited mail in my life. There's a form you can fill out at the end to dispute the mail blocking once you've ensured you follow all of the guidelines. I filled in the form this morning, and am waiting for a response. I think you're just falling foul of a ridiculously and unreasonably heavy-handed anti-spam process. M
