Unfortunately, I did the test some weeks ago, and the logs have been rotated away... I don't think I'd like to bother 3500 users again with my mass emails... If you have a solution to test this, without real email... Finally, I'm not so sure about the email being resent because of unreachable recipients. One thing I remember: In the postfix spool, in the defered dir, there were LOT of emails with different hash names. Looking in some of them, I noticed recipients duplicated in several of them, this should not be normal... In the logs, I could see some these hashed defered emails being repeated several times, each time with a cause why the mail was being defered. There surely is something wrong in my setup. However I have thousands of mails per day being sent (one by one...) correctly from the same forum.
