Dear Maintainer,

we have a problem with go-mmproxy that is fixed upstream.
See: https://github.com/kzemek/go-mmproxy/issues/13

We are using go-mmproxy for our ldap/smtp loadbalancing and we are seeing a
lot of RST packets (one for each closed connection), that might influence the stability of existing
connections.

This behavior was fixed in go-mmproxy 2.2.2:
https://github.com/kzemek/go-mmproxy/pull/14/files

If it is possible, please review the upstream bugfix.

Regards,
Johannes Kampmeyer
