Hello,
I have a Plesk server running on DigitalOcean. DigitalOcean IP addresses all get blocked on one Spam list no matter what you do. This causes a rare amount of outgoing emails sent from Dovecot/Postfix to bounce back.
I found a way to fix this by rerouting your outgoing mail server to use a sending service like Mailgun or Sendgrid here:
docs.plesk.com
What I noticed though was in order to switch from Postfix to MSMTP, it requires that you also uninstall Dovecot Imap/Pop server. Would this delete all current mail in my email accounts? It seems like it's removing the entire inboxes. I haven't tried yet until I can be sure.
Is there a way to instead modify Postfix to reroute all outgoing mail using the relay service? Or reroute certain domains to use the relay service? This would be my ideal option if possible.
Thanks!
