04-Nov-2026 — flag off-domain senders and sanitise extra addresses #364

build 1060 — commit 1f25561

On Committee Settings → Outbound email, an address that is not on the group's domain is marked as not on the group domain and cannot be chosen as the default sender. Existing records are left as they are.
When you add or rename an extra mailbox, spaces, the domain, and other invalid characters are stripped as you type. The local part must start and end with a letter or number, and Add or rename will not save an invalid address.
