Select email signature based on From address / sending alias

We have users with multiple SMTP addresses/aliases on the same Microsoft 365 Exchange Online mailbox. For example, a user may send from either user@maxdelivers.com or user@marcompanygroup.com.

We need INKY Email Signatures to select the signature profile based on the actual From address/domain of the outgoing message, rather than only the mailbox/account.

Example:

user@maxdelivers.com → Max Distributing signature
user@marcompanygroup.com → MAR Company Group signature

Ideally, signature profiles would allow rules based on the sender’s actual From address or From domain.

This is important for organizations that operate multiple companies or brands within a single Microsoft 365 tenant and use Microsoft’s Send From Alias functionality.
