Hi there,
I hope someone can help us or can give us a tip or direction how to solve the next problem?
We started using the standard build in email from magento 2. Only we found out a lot/most emails that customers would receive goes directly in their spam folder because fe. Google mention "Gmail cannot verify that this message was sent by copyshopdehaan.nl (and not by a spammer)"
After a heavy discussion for 4 weeks with our supplier they recommended a SMTP extension so we went for Aitoc's SMTP which being installed. After installing and we did setup all credentials/ports etc we got only failure notices after magento 2 sends automatic order, invoice, contactform emails, all came back with error code 550;
91.184.19.251 failed after I sent the message.
Remote host said: 550 Messages should have one or no Content-Type headers, not 2.
