Sun Java System Messaging Server 6.3 Administration Guide

12.12.2 Channel Operation Type

Keywords: submit

Messaging Server supports RFC 2476's Message Submission protocol. The submit keyword may be used to mark a channel as a submit-only channel. This is normally useful mostly on TCP/IP channels, such as an SMTP server run on a special port used solely for submitting messages; RFC 2476 establishes port 587 for such message submission use.
