I hope I got the message through that the problem is with phpbb and not with postfix itself. phpbb must have injected multiple messages with the same recipients.
Yes. I just wanted to state (again) that this is definitely not the fault of postfix.

Thanks for all your responses.
Phpbb could of course be the problem. I was wondering how this kind of basic bug could still exist in postfix...
If it is a phpbb bug, is there an easy way to have a fake smtp server, so I can catch the bugged phpbb smtp request? (I can setup another smtp port in phpbb...)
Before you blame phpbb, check your data for duplicates.
Also, check that you have a recent version, there was a version a while ago that became very well known for a very bad reason - it was vulnerable to external attack, and external attackers were very successful.
How many computers can you use to try to debug your problem? I don't like to test on production systems, do you?
