If PAM is the issue why we don't see this behavior with other services as
well?
It will be fairly simple to setup some scripts to hammer a server or even
use Jakarta Jmeter to create some load simulations and quickly see if that
is the case.
If anyone is interested in working together with this issue let me know.

On our experience this problem went away when we convinced one of our
customers to change the behaviour to check email Every Minute 90 users one
IP every minute,
this has kept the horrendous problem away,
But gives at least in our case clues about the problem.
PAM Eficiency, I would go for the caching option, I know its not easy to go
testing features on productions servers ...
Good luck and please report back

I think it is imperative for us to find the cause of Dovecot's problems and
resolve them. Email is a mission critical component for most webhosting
accounts, probably more so than the actual serving of web pages. If we
allow this deficiency to cripple the BQ platform, it's going to kill the
project. No one will want to migrate to or install a web hosting platform
that will hobble the email aspect of your operations.

I think this is the issue that will never die.. I am seeing the same
behavior on servers with the latest releases also...

When I had the problem, there also seemed to be a problem with webmail and
FTP.
I had it on one server with a slow raid card. Now, the only time I seem to
have it is when I get a dictionary attack using pop 3.
