Recalling messages doesn't work with normal mailservers, only
Microsoft Exchange servers.

I just had an interesting thought. Would it be possible to
spoof Microsoft recall messages? Post-reception removal of
spam? Denial of service?

Would it be legal (sender spoofing), even on your own servers?

Possible, yes - up to a certain point. Worth the effort? Not much.

I always thought the concept of "recalling an email" was absurd. Only
Microsoft could invent such an idea.

Its a bit like recalling a parcel you posted to someone, expecting them
to pack it back up and give it back after they received it.

Completely mad.

Absolutely. Like getting the pig back if the bacon tastes funny.

To me, it's just a big red flag to read whatever juicy tidbit has just been fired off prematurely from an inattentive co-worker! ;)

Well, actually ... GroupWise could do this as well (and usually more
effectively than Exchange:-). Now, GW doesn't qualify as a normal
mailserver, and isn't ... that lively... these days, so...:-)
Not that any recall would work once the email reached a maillist server.:-D
Anyway, a nice little chuckle.


Cheers
