I noticed that emails that are sent from the application come from 2 different addresses:
maildelivery@invoice.services and maildelivery@invoicing.co.
The ones sent from invoice.services are showing “Invoice Ninja” as the sender, not the name of my company like the ones from invoicing.co. (The reply-to header is correct though…)
Sending to microsoft mailservers has required us to change the way mail is delivered. This is one of the changes that we’ve needed to implement, to ensure that mail is delivered to those particular users.
