If your email administrator has enabled SMTP authentication on the Sophos Email Appliance, it is possible to send email messages from a computer on another network, and they will be delivered as if sent from your network account that is hosted by the Sophos Email Appliance.

What to do

Before you can send email from outside the network through the Sophos Email Appliance, however, you must set up Outlook to authenticate with the Email Appliance using SMTP.

If you are using different email software, such as Outlook 2010, see the documentation for that product.

Note: This form of authentication only allows you to send mail from an external network. If you also want to externally retrieve email that has been sent to your internal network account, your administrator must configure this separately.

To configure SMTP authentication:

  1. In Outlook, select Tools>Account Settings.

  2. Select the mail acccount to configure, and click Change. (If Outlook is not configured to use an internet email account, you will have to create one first.)

  6. Select Log on using, and then enter the User Name and Password as instructed by your administrator.
  7. In the Internet E-mail Settings dialog box, click the Advanced tab.
  8. In the Outgoing Server (SMTP) text box, enter the port that the Sophos Email Appliance uses for SMTP authentication. This should be given to you by your administrator. The default port is 587.

  9. [Optional] If your administrator also instructs you to enable Transport Layer Security (TLS) encryption, from the Use the following type of encrypted connection drop-down list, select TLS.
  10. Click OK.
