There are various ways that network administrators can restrict outbound messages in order to prevent users from sending out SPAM. As a result, you may need to modify a couple of your mail settings to ensure you are using the correct options. Instructions are provided below for changing this setting in Microsoft Outlook. If you follow these steps and still cannot send mail, you may need to change the outbound mail server to one that is managed by your ISP or network provider.
In Microsoft Outlook:
- Open Microsoft Outlook.
- Go to the File tab, then select Account Settings > Account Settings.
(In older versions of Outlook, go to Tools -> E-mail Accounts in the menu bar, then select “View or change existing e-mail accounts”, and then click Next..)
- Select your e-mail account from the list, and click Change.
- Confirm that mail.yourdomain.com (for example, mail.kncihosting.com) is in the Incoming mail server and Outgoing mail server fields.
- Click More Settings.
- Click the Outgoing Server tab, and ensure that the box “My outgoing server (SMTP) requires authentication” is checked.
- Click the Advanced tab.
- Type “26” in the Outgoing mail (SMTP) field.
- Click OK.
- Click Next, and then click Finish.
