[Mimedefang] Poll: Who uses the "filter_tick" and "map" functionality of MIMEDefang? (-X and -N options to mimedefang-multiplexor)

I used to use filter_tick to basically do keep-alives on the tcp connection
from the milter to a database or ldap server. This, I hoped,
would solve the problem of the remote server silently
closing the connection down because of inactivity.
I found that it was more appropriate to instead
- Keep track of approx last time the connection was used.
- And if the last time it was used was larger than some threshold
= I would first issue a noop or other low cost operation
= If the noop failed, I would reestablish the connection
= If the noop succeeded, I would merely continue
So I no longer need the filter_tick function.
(Nor do I use the '-N sock_map' feature.)
Thanks for asking,

-----BEGIN PGP SIGNED MESSAGE-----
I'm looking at stripping out unused features from MIMEDefang.
1) Does anyone use the "-X n" feature that calls a function called
filter_tick every "n" seconds? If not... I'd like to nuke.
2) Does anyone use the "-N map_sock" feature that provides a
SOCKETMAP to Sendmail 8.13+? If not... again, I'd like to nuke.
