According to RFC1123, there are two approaches for time-outs in the sender-SMTP:
1. limit the time for each SMTP command separately, or
2. limit the time for the entire SMTP dialogue for a single mail message.
A sender-SMTP SHOULD use option (a), per-command timeouts.Timeouts SHOULD be easily
reconfigurable, preferably without recompiling the SMTP code.
The value of timer [ ] shown above are recommended by RFC1123.
