Ok, sorry.
I've modified subject.

We have no greylisting activated.
So, you think that sender verification could be the problem.
There's some way that can help me to improve sender verification?

This isn't an answer to your question, but rather a thought about your post.
These mailing lists are archived for later searching and non-descriptive
subjects such as "PROBLEM" or "HELP PLZ" (we've all seen
these) dampen that process. Also, many people on these lists selectively
read through these posts based on the subject lines. Using a specific
subject line in your post will both waste less time and increase the
likelihood of somebody being able to assist you.

As for your problem, sender verification is probably a large part of your
problem. If you're going to set bounce_queue_lifetime so short, just set it
to 0. That way it will only be tried once. I wouldn't set
maximal_queue_lifetime so short, as it will eventually come back to bite you
when somebody's server is down for a short period of time, and it probably
breaks communications with servers that employ greylisting.
