Hello!

So I was using elasticmail but I decided to change switch over to mailjet because my elasticmail account had some problems. From what I read it was simple, just changing the SMTP settings in the app.ymp file then rebuild which I did. I have linked my domain to mailjet and SPF/DKIM status is OK. I double checked my SMTP/API settings multiple times and they are correct. But the email services are not working and I’m not sure what could be the problem as I can’t see anything being wrong, elasticmail was working with no problems beforehand.

Here’s more info:

**sidekiq error:** Jobs::HandledExceptionWrapper: Wrapped Net::OpenTimeout: execution expired

I’d appreciate any help, thanks!
