So after the SMTP drama I had with VULTR. I decided to go for an external service that i saw somewhere.
SENDGRID seems to have a nice free option to get the sites up and running at least. But I'm flabbergasted at how hard it was to setup.
I'm running CYBERPANEL / OPENLITESPEED.
I followed this guide, to install it via SSH. https://sendgrid.com/docs/for-developers/sending-email/postfix/
But yet, I still cannot SEND emails, I can receive them just fine. the API is connecting, but e-mails just won't send. What am i doing wrong? :(
The DNS was all configured too FYI. I added everything asked into Cloudflare, and have cloudflare sync enabled. Or does VULTR also restrction SMTP from other servers? am i missing something?
