Unable to send email when reply-to field is different from account email.
My ATT server is yahoo and I assume the problem is the same at the ATT server. This is Outlook 365 on windows 10.
I own a domain name and I use that as my reply-to address. It seems that AT&T (yahoo) is checking to see if the account email matches the reply-to email. I have never had a problem with that until recently. I set the "reply-to" email to blank (deleted it from email account) and I can now send email using outlook. Gmail account in Outlook never had a problem with having reply-to different from the account email.
For years now, I have my domain name forwarding to whatever ISP is my provider but it seems I cannot do that anymore, at least with AT&T.
Currently, I get all types of spam phone calls on my AT&T iPhone daily, and the caller ID is spoofed. So it seems AT&T cannot stop a fake phone call but they can stop an email from going out that uses a different return address. What hypocrisy!
