Communication Protocols
The set of conventions necessary to achieve facsimile-compatible service covers basic data transport, doc-
ument data formats, message (document) addressing, delivery confirmation, and message security.
Protocol supported by the UF-E1 is as follows:
TCP 3 Way Handshake &
Opening Session
[5 minutes]
[5 minutes]
[5 minutes]
[2 minutes]
[3 minutes]
[3 minutes]
[10 minutes]
According to RFC1123, there are two approaches for timeouts 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.
