SMTP-Proxy: Authentication

This ruleset allows these ESMTP authentication types: DIGEST- MD5, CRAM-MD5, PLAIN, LOGIN, LOGIN (old style), NTLM, and GSSAPI. The default rule denies all other authentication types. The RFC that tells about the SMTP authentication extension is RFC 2554. You can add, delete, or modify rules.

  1. On the Edit page for the proxy, select the Proxy Action tab.
  2. From the ESMTP drop-down list, select Authentication.
    The Authentication page appears.
