the Registered Ports, and the Dynamic and/or Private Ports.

The Well Known Ports are assigned by the ,-+- and on most systems can
only be used by system >or root? processes or by programs e@ecuted by
privileged users.
Ports are used in the T%P .R/%A2$1 to name the ends o logical
connections which carry long term conversations. /or the purpose o
providing services to unBnown callers, a service contact port is
deined. This list speciies the port used by the server process as
its contact port. The contact port is sometimes called the
<wellCBnown port<.
To the e@tent possible, these same port assignments are used with the
)DP .R/%A4D1.
The range or assigned ports managed by the ,-+- is !C"!#$.

8essages received on this port are deined to be submissions. The protocol used
is 6&8TP .&8TPC8T-, 6&8TP1, with additional restrictions as speciied here.
While most email clients and servers can be conigured to use port 3DA instead o

use port #3 or message submission, by designating some hosts to be 8&-s and
others to be 8T-s.
