| Description | This article describes how to bypass sender alignment check when there are mismatch in Reply-To with the Header From. |
| Scope | FortiMail v7.6 |
| Solution |
Starting from FortiMail v7.0, Sender Alignment will check for Header From and Reply-To mismatch. When the Sender Alignment is enabled at AntiSpam Profile, email with a mismatch Header From and Reply-To will take action by FortiMail.
Before firmware v7.6, the option to bypass the Sender Alignment check for mismatch in Reply-To is by disabling the Sender Alignment check in the AntiSpam Profile or creating an Exempt Rule for the specific sender in Impersonation Profile. By doing this, it will also bypass the email with mismatch Header From and envelope (Mail From:).
In firmware v7.6, Sender Alignment features can control to bypass only mismatch for Reply-To. To bypass the Sender Alignment check for Reply-To, disable the Reply-To button in the AntiSpam Profile -> Business email compromise -> Sender Alignment. FortiMail still takes action for Sender Alignment mismatch for Header From with envelope (Mail From:).
