Hello,
Though the fix does not make sense, I have found the issue. The email address for the support contact was blank and by default was using a different email then the sending account. I set the email address to the same address used for the sending account. Emails are now being sent again.
My questions:
- Why does the support email address need to match the sending email address? In my case, the sending account is an unmonitored account used by our online applications for sending emails.
- As this was previously working, was this requirement something new in 2.7?
- Is this a requirement in version 3.x?
Best regards,
Ron
