ISS is now able to provide an Authenticated SMTP service, so that users of @essex.ac.uk email accounts may use the Essex SMTP server from any location in the world. Initially, use of the service will be voluntary. However, we will eventually make the use of Authenticated SMTP mandatory.
Unless you read your mail with Outlook in Corporate Mode (ie, as the Service routinely install it), or by using Outlook Web Access (ie, by using the webpage https://email.essex.ac.uk/), then you will need to reconfigure your mailer to use Authenticated SMTP. Instructions for various mailers are below.
The Service has introduced the alias smtp.essex.ac.uk for one of our SMTP servers, and in the examples below this has been used as the name of the server to use. The other servers (serlx14.essex.ac.uk and serlx15.essex.ac.uk) are also capable of authenticated SMTP, and these may be used in place of smtp.essex.ac.uk if this is unavailable. In addition, there is an authenticated SMTP listener on the exchange system's Hub Transport server serht01.essex.ac.uk, which should not normally be used, but may be necessary to send email to some protected exchange mailing lists.
Microsoft supply two similarly-named mail programs, Outlook and Outlook Express. Despite the similarity of the names, the products are very different. The name of the program is shown at the top of its window, so if when you start your mail program the top of the window contains the phrase ”Outlook Express“, then you must follow these instructions.

If, however, the top of the window contains “Microsoft Outlook”, you have the full Outlook.

To complicate matters still further, you now need to know what “Mode” is running in. If you do not know the answer to that,
- click on Tools. Outlook may now display the full list of avaialble tools, or it may display a truncated list, with a double chevron at the bottom. If you have the chevron, clicking on it will display the full list, or you can wait 5 seconds and it will be displayed automatically.
- If “Services” is an option, then you have Outlook 98 or Outlook 2000
- Click on Services
- If the default service shown is “Microsoft Exchange Server”, then your Outlook is in Corporate Mode, and you need do nothing further
- Click OK to exit
- If “E-mail Accounts” is an option, then you have Outlook 2002 or Outlook 2003
- Click on Email Accounts
- Click in the box marked “View or change existing email accounts”
- Click the Next box
- If one of the accounts shown is “Microsoft Exchange Server”, then your Outlook is in Corporate Mode, and you need do nothing further.
- Click Finish to exit.

On Windows, Outlook Express version 5 or 6 both require the following changes to use authenticated SMTP:
If you use Outlook Web Access, by using the link on the Student Portal webpage, or otherwise opening a webpage such as https://exchange4.essex.ac.uk/exchange/, then you need do nothing further.
Edit your .pinerc file to specify the use of SSL, and to add your username to the smtp-server: eg
smtp-server=smtp.essex.ac.uk
would become
smtp-server=smtp.essex.ac.uk:465/ssl/user=username
Pine will then request your password before sending mail for the first time each session.
While in Netscape Communicator, under the Edit menu, select Preferences.
These Settings work in most cases for both Mozilla Thunderbird and Mozilla Mail
These settings may not be appropriate for email
to some Essex mailing lists, which are protected
in such a way as to require authentication by the exchange system itself. In such a case it is necessary to use
the exchange system's Hub Transport Server, serht01.essex.ac.uk. The necessary settings
(with your own username, of course) are

These instructions will work for Eudora 6.0 and above. Authenticated SMTP is not available in earlier versions of Eudora.

These instructions will work for MAC Eudora 6.2.4
This assumes that you are using Dominant Personality for checking and sending mail. You may have set up an Outgoing Mail personality using your ISP's smtp server up until now.
