Name:
    SMTPMTA_EXPN

Syntax
    SMTPMTA_EXPN=Value

Applies to:
    Servers - SMTP

Add-on:

    First Release:
      4.6.2

    Obsolete since:

      Category:
        Mail, SMTP

      Default:
        0

      UI equivalent:
        None

      Description:
      Allows an administrator to expand a mailling list or group and get the individual addresses that make up the list. This can create security issues, so thed default for this variable is off.

      When enabled, the administrator can use the EXPN command from the system console to expand a specific group. For example, EXPN Group EXPN only provides valid returns for Valid Groups (Multi-Purpose and Mail)Users and Groups with Notes Routing (Group%notesdomain). Mail-in Databases and Access
      Groups will be returned with an error. The Group will be expanded and each address returned. Non-SMTP addresses are converted to SMTP addresses following Outbound Conversion rules whenever possible. This includes the use of LMBCS encoding as a worse case solution for Non-Ascii Group Members. Any address that still cannot be converted will be returned as an error. Group members that are themselves Mail-In DBs or other Groups will be returned as a member. The command does not expand subgroups (groups within groups).

      "550 argument is not a valid Group" - If the argument is not a Group
      "550 argument is not a valid Group" - If the argument is not found
      "553 argument is not unique" - If the argument is not unique

      (If the argument maps to 1 user and 1 group rather than 2 groups it will still return the 553 error as this maps to how the inbound conversion code would handle that address.)

      This Setting is Introduced in version 4.6.2
