Seller forgive me if this is perfectly above board but...
Your issue is his having his email address on it?
Against rules, but I don't object given ebay fees.
For all we know it may be genuine; however I can think of a number of things that (whilst individually you might be ok with) collectively would make me run a mile:
New ebay account
Inability to spell component names
mis matched brakes
unlikely forks for frame
badly fitted components (missing/rounded bolts on a stem)
quick sale / out of ebay contact details
