Thanks for the answer. I started to suspect that as I composed the question.

On the other hand, I just subscribed to an open office announcement list 
by sending an email, and got this back as the subscribe address they 
got: [email protected]. I wonder 
how I will unsubscribe??

Maybe they use the sender field to make sure they are not getting 
spoofed subscriptions requests?

SRS is a feature that works on the SMTP Envelope Address of SMTP not on
the From header in the mail message. So the end user should not see the
srs in his final mail unless he looks at the headers. There he/she
would find the srs address in the Return-Path or Sender header but not
in the the From header.... .... unless the mail was sent without From
header and your MTA inserted the envelope address instead.
