Steps to change the outgoing mail (SMTP) port in order to bypass a block of the default port 25.
Since Microsoft Outlook 2003 is the most common e-mail client we deal with that is the one we will describe the configuration for but most e-mail clients will have a similar configuration.
1) Within Outlook select Tools from the menu bar
2) Select Email Accounts, this will open a new window
3) Select View or change existing e-mail accounts and click Next
4) Highlight the e-mail account name and click Change
5) Click the More Settings button
6) Select the Advanced tab
7) In the field next to Outgoing server (SMTP): remove the number 25
8) In the same field enter 587. The only 2 port numbers HostWorks will accept for outgoing e-mail are 25 and 587.
9) Click OK, click Next, and click Finish.
