Are you sure that it's something on the server that's dropping the
connection? Something that sounds very much like this happened to us and
it was usually fixed by increasing the timeout set by the client; it
appears that some (all?) clients will drop the connection if they haven't
received a command in whatever their timeout setting is, even if data is
being sent. (This is just a guess, however, based on observed behaviour,
and I also don't know if this is the "approved" behaviour for mail
clients.)
In any event, you might want to increase the timeout setting on the
client, if possible.
