Sold something on ebay and had an email from the winner clarifying the address, however when I click reply the 'to' address is different to the address that the original email came from?

Any ideas why this is?

The new address seems like a company one so I don't want to send it off if it's wrong, but then if he set it up so that the reply goes to a different address I don't want to change it back to the original one. I didn't think you could actually do this sort of things with email though..... set up a different reply address

in outlook express (and i'm sure in outlook, and probably many other email applications) you can specify a 'reply-to' address.
