We have a number of users who are either using email via on-premise Exchange, hosted Exchange, or Office 365 business/enterprise. Exchange checks both the envelope-From address (SMTP FROM) and the header-From address (actual From address in email) for both SPF and internal domain blocking. While this is not true of all mail server software, it is true of all Exchange server versions which encompasses the vast majority of enterprise and business email servers. Recently (within the past year), Office 365 finally implemented DMARC on their servers for North America customers but not all customers have had the knowledge or initiative to properly implement it.
Thank you for that explanation! This has been something that I've been dealing with for a year now, and I was unable to get an explanation of what was going on from anyone, mainly because I think most people didn't understand what was happening.
I am requesting that, in addition to the Reply to Group setting, we have the ability to turn on the "via groups.io" setting for all users in a group. This would allow group owners to resolve this issue with business-class mail servers for their individual group(s) without adversely affecting other groups.
I think perhaps the best thing to do is to add a checkbox, separate from Reply To, that when checked will munge all From lines in messages to a group. Perhaps call it 'Convert All Email From Addresses To Be From Groups.io' with the help text being: "Only use this feature if you use Office 365 and have had complaints from users about email spoofing.'
