Important Points
- These instructions assume your email server / account has already been
setup and is collecting email correctly.
- Take a note of any settings you change.
- Only change the items specified - you should not need to change your
incoming email settings.
Step One
- Using Exchange System Manager navigate to the 'Servers' container.
- Drop down the 'Protocols' container.
- Find the 'SMTP' protocol and select 'Default SMTP Virtual Server'.
- Right click on the default SMTP virtual server and choose 'Properties'.
Step Two
- Click on the 'Outbound Security' button.
- Select 'Basic authentication' and enter your AuthSMTP username and
password.
Step Three
- Click on 'Outbound connections' on the delivery tab.
- This will show you what outgoing SMTP port number you are configured to
use - if your ISP is blocking port 25 enter port 2525 (but even if they do
not block it at the moment we still recommend using port 2525 anyway!).
Step Four
- In order to get mail to relay through our servers you will need to setup
the 'Smart Host' setting on this screen.
- This is what tells Exchange to delivery all mail destined for the
internet though our servers.
- Enter the SMTP server name we gave - for example: mail.authsmtp.com
Step Five
- You will need to restart your SMTP service for all changes to take
effect.
- Any mail that is currently in the queue might not take these new
settings so you might need to send a new piece of mail to test it.
- After sending a test email you will want to check the outbound queue on
Exchange to make sure that the mail did not get stuck in your outbound queue
because of authentication errors.
Step Six
- On some systems (depending on the configuration) you may need to go to:
Routing Groups
- Select the 'Connectors' and 'Internet Mail Service'.
- Right-click and select 'Properties'.
- Find and select 'Forward all mail through this connector to the
following smart host'.
- Select 'Outbound Security'.
- Enter your SMTP smart host user name and password in the 'Basic
Authentication' section.
Optional / Recommended Step
- By default Exchange 2000 will accept email for any address at your
domain name and put it into a local queue to be processed. The vast majority
of this email will be junk / spam messages from spoofed or fake email
addresses going to invalid addresses @ your domain name.
When Exchange processes this email it will send an NDR / DSN (Non-Delivery
Report / Delivery Status Notification) email back to the sender of any email
that is going to an invalid address but because the original address was
spoofed or fake the messages will either fail or go back to the person who
actually uses the true email address, who may then report it / you as spam.
This problem is known as Backscatter and you may find it will clog
your mail queues and use up / waste your AuthSMTP quota.
