trouble setting up Notification Target w/ external SMTP server (SendGrid)

[the block]

New to Proxmox. I want to set up notifications in case something happens that I need to know about.

I use SendGrid (100 free per day) for this for my other services. I've essentially copy/pasted the config from how the other services (that work) use SendGrid, so I expected this to just work similarly.



However when I go to Test the connection, this is the error I get. Doesn't seem like it's even getting out. Not sure what I'm really missing here, as it's always just worked after putting in the server name, port, username, and password.



Is there something else I need to check or configure to let this get out to SendGrid?

I think either the port or the encryption setting is wrong - should be either STARTTLS via port 587 or TLS via port 465.

Hope this helps!

That was it, wrong port. I had documented 587 in my notes, but it was 465, doh. Glad it was something simple. Thanks for the reply.
