I am confused by this:

This whole session lasts somewhere between one and two
seconds, from the time the client connects to the time
that the client logs out, having completed the session.
Is the long delay something you're observing in your web
mail front end?

The other sessions in your log extract seem to be about
the same length.

unlikely -- per above, there doesn't seem to be a
significant delay between connecting and authentication by
MySQL.

--=20
