because you signed up for the mailing

maybe he didnt.

i've heard of cases, where spammers used the subscribe address of 
mailinglists as envelope sender. an out-of-office reply is sent to the 
subscribe address from the target of the spam - the mailing list software 
sends a confirmation mail - the autoresponder correctly authorises the 
the subscription request.
  
Yea,

... and he can be unsubscribed the same way ...
I think email from fake address (eg. from his) will work too for unsubscribing..
...but then again, thats what you get for sending out-of-office 
autoresponses.

nevertheless, no reason to make a fool of oneself.

best regards
