Testmail “SMTP Connect Failed”, but Mails works on local

Hey man,

you doing a great job answering all these topics here.

I couldn’t find my probleme in the past threads, so here’s our setup:
– Updated WordPress and WP Mail SMTP Plugin.
– Running on PHP 5.6.38
– Mails are sent through mail.some-domain.org @ 587, which works well on lokal since years. But doesn’t work with WordPress out of the box.
– So mails are on mail.some-domain.org and our web/wordpress is on another-domain.de <= maybe it’s cross domain related error?
