Hi,
I've noticed lately that I have a lot mail stuck on queue, most are
intended for yahoo users where most of the emails being sent to yahoo
contains attachments mostly image files, flushing the queue doesn't do
anything, and most of all yahoo doesn't do anything to my complaints.
Any idea how to go about this?
Here's my postfix configuration:
