X-Confirm-Reading?

[Stasinos Konstantopoulos]

Hi,

I got an email today with the following line in the header:

X-Confirm-Reading-To:  <sender's address>

from somebody using Pegasus/Win. I guess this is a request to the
receiving MUA to send back an ACK upon opening the message, and I just
wanted to make sure Mutt is not (at least by default) part of this
conspiracy against privacy.

Thanks,
Stasinos
