I configured runway to send emails with Postmark and while locally works perfectly, in production it gives
SMTP connect() failed. ... Locally I use a docker image with PHP 7.1.3 and the production server is a Siteground PHP 7.0.25. I've tired with Ports 25, 2525 and 587 but all of them fail. Anyone has an idea where to start looking or what to ask Siteground people for?
