Configure sender address format #5716
Description
Currently Firefox relay sends emails with the following format for the sender:
[email protected] [via Relay] <[email protected]>
This can give troubles to some clients (Thunderbird mobile/K9) but also be flagged as forged address by other clients (Gnome Geary).
It would be nice to configure the format to avoid an explicit mail address in the sender's name.
For instsnce, this is what can be done on simplelogin.io (original name):
John Wick - john at wick.com
John Wick - john(a)wick.com
John Wick
john at wick.com
No Name (i.e. only reverse-alias)
