1. You have said nothing about whether the bounces are for inbound
mail to invalid recipients (fix recipient validation, which you
disabled) or caused by outbound mail sent to invalid addresses
(fix your mailing lists).

2. You have not posted any information from QSHAPE despite multiple
attempts to point you at:

3. You have not posted the requested statistics of "c+d" delays
sampled over a few hours of mail deliveries (mean, median,
and an ASCII histogram would be useful).
4. Congestion is not a single message phenomenon, you MUST identify
the bottleneck by understanding which destinations account for
the majority of the delays, where that mail originates, and why
its delivery is slow.
Please don't waste our time with further questions that are not
backed by the relevant quantitative information.
