Such disconnects may be due to a router or a firewall (or something like
an ADSL modem/router) which sets a timeout on idle TCP connexions
(reflexive ACL, NAT mapping...). It is frequent to have no more than 5
minutes timeout. Workaround is to force the client or the server to keep
the connexion alive by sending some packets at an interval less than 5
minutes, for example by polling new mail every 3 minutes.
