Ive never used express before either but ive foudn some basic things you can try.....

Troubleshoot Outlook Express Mail Sending Problems

To make Outlook Express send mail again:

1 Check your outgoing mail server settings.
- Select Tools | Accounts... from the menu, highlight the desired account and click Properties.

- Make sure the correct server name is entered under Outgoing mail (SMTP): on the Servers tab.

- On the same tab, verify My server requires authentication is checked if needed (which is typically the case). Under Settings..., you can specify a user name and password different from your incoming mail credentials.

- On the Advanced tab, make sure This server requires a secure connection (SSL) is checked under Outgoing mail (SMTP): if your outgoing mail connection must be encrypted.

- Check the port under Outgoing mail (SMTP):, too. Typical ports include "25" and "465".

2 Make sure your Sent Items folder is not overly large.
- The folder can hold 2 GB at most. To check the size, go to your Outlook Express store folder and examine the Sent Items.dbx file's size.

- Move messages from the Sent Items folder in Outlook Express to another folder. Set up folders for all mail sent in a year, for example.

- Make sure you compact folders manually after moving messages.

If none of these can help you im afraid im all out of ideas...
