[Dovecot] testing LDAP connections

Hello all,

I haven't looked into the source code, but i suspect that LDAP connections, once established, are not tested properly.

My scenario is the followind:

Dovecot server <--------> firewall <---------> LDAP backend

What happens is that the firewall has a security feature which

basically make de firewall box "forget" about connections that are idle for more than X period of time. That particular setting is 30 minutes right now. When that happens, neither the LDAP backend or the Dovecot server get any type of notification, and for all they care the connection is alive and well. This is a very common implementation in firewalls nowadays.

So my question is, is there any way to make dovecot re-open a new

connection if there is a timeout while trying to use a connection already opened? I believe that this could be of great benefit for those who don't have their servers on the same physical network.

Thanks in advance,

Hugo Monteiro.
