The defaults should give pretty good performance with good
tolerance for a flaky connection.
If you find the defaults insufficient, here are some relevant
Just as general info, if the connection stays active but is
really slow (regardless if it's due to bandwidth or
transmission errors) mail should keep flowing and the default
settings should work well.
If the connection drops frequently, mail will be deferred and
may have trouble ever getting delivered. There isn't a good
workaround in postfix (or any MTA I know of) for a connection
that drops frequently.
