Removed the "timeout=300s" directive from SMTP examples. Such an initial timeout is too long, and the default timeout of one minute is long enough. By removing it, we purposedly ignore the requirement of the current SMTP specification to set it to at least five minutes: http://tools.ietf.org/html/rfc5321#section-4.5.3.2 Submitted by Maxim Dounin.
