I am using smtp2go as a mail relay for all alerts and this has the tendency to be flagged as spam by some mail hosts.
I currently have a controller set up on my own VPS which is configured to send email alerts via Fastmail's SMTP server (using credentials specific to the controller). Since my personal mailbox is also with Fastmail it ensures delivery into my inbox. I've requested an account on your system so I'm just wondering if the same configuration can be used or do you have outbound SMTP blocked?
