I can receive my email OK, but cannot send email using Outlook 2003.
You can try sending the email on port 26, which is an alternate SMTP port and see if that works for you. For Outlook:
1. In Outlook, drop down the Tools menu.
2. Choose Accounts or Account Options.
3. Click on the Mail tab.
4. Click on Properties.
5. Click on the Advanced tab.
6. Change the outgoing mail from port 25 to port 26.
7. Make sure that the box that says "This connection requires a secure connection(SSL)" is NOT checked.
8. Click OK.
9. Restart Outlook.
You may want to try using your ISP's SMTP Server for sending mail. The setup will be similar except for the outgoing SMTP server it will be your ISP's Server. Please ensure that your "Reply to" address is still your email address with HostMonster.
