Sun Java System Messaging Server 6.3 Administration Guide

ProcedureTo Add Distinguishing Authenticated Submissions

  1. In your configuration file, add a new TCP/IP channel definition with a distinct name; for example:

    tcp_auth smtp single_sys mx mustsaslserver noswitchchannel TCP-INTERNAL

    This channel should not allow regular channel switching (that is, it should have noswitchchannel on it either explicitly or implied by a prior defaults line). This channel should have mustsaslserver on it.

  2. Modify your tcp_local channel by adding maysaslserver and saslswitchchannel tcp_auth, as shown in the following example:

    tcp_local smtp mx single_sys maysaslserver saslswitchchannel \
    tcp_auth switchchannel

    With this configuration, SMTP mail sent by users who can authenticate with a local password will now come in the tcp_auth channel. Unauthenticated SMTP mail sent from internal hosts will still come in tcp_internal. All other SMTP mail will come in tcp_local.
