I have postfix, which I use on server just for sending emails. It's not used for incoming emails. It works flawlessly, howevere one email is stucked SOMEWHERE and postfix keeps sending it all over again. Usually twice a day, but not at fixed times but randomly.
I've checked the postfix queue by using
postqueue -p
And I have deleted the queue by using
postsuper -d ALL
The message wasn't in the queue and I have no idea where it is coming from. All other emails are sent correctly.
Can anybody help me with any advice what to check or where to find this specific email and where is it coming from ?
Edit: log from /var/log/mail.log

I'm sorry, but under more investigation into this problem, it really wasn't fault of postfix. User unknowingly kept requesting page that sent this email every once in a while. So this is a explanation to my question.
