I have roundcrube on my hosting and I use it to read all my emails. This client offers feature to install my private filters (by using sieve) and I found out there’re 2 options for from
- Envelope From
I was curios to find out, what is the difference between these two.
The reply from exo-host.com – the best hosting solution world-wide (IMHO)
- FROM is a part of the message. FROM will show in your Outlook/Thunderbird
- Envelope From is a part of the protocol. You cannot overwrite Envelope From. For instance. Envelope From is always the REAL account that sent an email
