Quote header in replies shows alias address instead of original sender #946

When replying to a forwarded email through Addy, the quoted text header displays the alias address instead of the actual sender's address.

Actual behavior:
On 23 Oct 2026, at 11:42, myalias@addy.io wrote:

Where myalias@addy.io is the receiving alias, and user@example.com is the actual sender.

Why this is a problem:

• Creates confusion about who actually sent the message
• The alias address (myalias@addy.io) is not the sender; it's the recipient

Reproduction steps:

1. Receive an email at an Addy alias (e.g., myalias@addy.io) from an external sender (e.g., user@example.com)
2. Reply to that email
3. The quoted text will show the alias address as the sender, not the original sender's address
