Jaylink5353 Hello! I’m trying to setup mailcow with my VPS, but they blocked all SMTP ports. I got a free trial to Brevo, a SMTP relay service, but I can’t seem to be able to add it. How do I do this?
D4niel The answers are (almost) always in the docs: https://docs.mailcow.email/manual-guides/Postfix/u_e-postfix-relayhost/
2Oscar Hi.. You can try Contabo VPS. They do not block SMTP port 25. Having said that, use MX Tools to scan IP address to see if it has been blacklisted as well. Contabo – https://contabo.com/en/vps/ MX Tools Blacklist check – https://mxtoolbox.com/blacklists.aspx Test your email – https://aboutmy.email/ Hope this helps…
