Services :: WebMail :: Secure SMTP
What is Taking Place?
Beginning in Fall 2009, all email clients (including those on-campus) must be configured to use Secure SMTP (the protocol that allows you to transmit email) over port 465 (the standard SSL port) with authentication (a user name and password). This migration continues the Secure Communication project that was started in 2005.
What settings are being changed?
The following settings will be enforced as of 10/18/09 (off-campus) and 4/18/10 (on-campus):
- Port 465
- Use SSL
- Use Password Authentication
Why are we making this change to Secure SMTP?
- Security
- Ease of use – email configuration will be the same regardless of whether clients are off-campus or on-campus.
Who needs to make these changes?
Zimbra and Outlook (with Zimbra) users
No changes necessary
Other email clients
Eudora, Thunderbird, Mac Mail, Entourage, or Outlook (without the Zimbra Connector) will need to make a small configuration change.
Scripted Process for Mail Sending
If you use a scripted process on a server to send mail, you will also need to adjust your settings. If that is not possible because of the service you are using, you will be required to register that server as a mail sender and continue using port 25.
