Configuration Options
CastleMail has a number of configuration options. The first thing you should do is to open the Preferences dialog either by choosing Preferences from the File menu, or by clicking on the Preferences button in the toolbar.
In the Preferences dialog you should set the values for your default SMTP Server, SMTP Port, and the HELO setting. In most circumstances, you would set these values as follows:
| SMTP Server |
Your ISPs SMTP server |
| SMTP Port |
25 |
| HELO |
Your computer name |
