Configuring External Mail Transfer Agents

If you did not select either sendmail or Postfix as the mail transfer agent (MTA) during PureMessage installation, use the instructions below to set up PureMessage to work with an existing MTA. This section describes configuring PureMessage for external versions of sendmail, Sendmail Switch and Postfix.

Note: As external/third party versions of sendmail and Postfix are not quality-assured for integration with PureMessage, Sophos reserves the right not to provide support for an issue that appears to be related to any such custom configuration, and may recommend that you install a version of sendmail or Postfix that is bundled with PureMessage to further a resolution.

If you are using Oracle Communications Messaging Exchange Server, you can configure a direct connection with the PureMessage milter as described in "Configuring PureMessage for Oracle Communications Messaging Exchange Server" in the Sophos Knowledgebase.
