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:

Jan,

Can you show us some of the queued mail messages with obvious edits to hide the destinations user name?

Also provide any logging information.

unfortunately we can't help you. yahoo throttle your mail. if this is a
problem, it means you send too much mail to yahoo. In this case, you
need to get whitelisted by Yahoo. and for that, you need to contact Yahoo.

there are things you could do to improve delivery. but these depend on
your IP, your geographic location, your domain, your helo, ... etc. we
cannot help a random gmail user improve delivery from example.com.
