It might be related to browser retrying the request several times
because it is a long task don't you think?
This could explain why there are several smtp connections.
Anyway I reported the bug to phpbb bug tracking.

Yes the phpbb is modded, but not by me. I'm just hosting it on my
dedicated server.
