Antivirus : Avast version 4.8 Home Edition ( build Feb2009 4.8.1335 )

Problem description
When I try to send and receive e-mail. I can only receive e-mail. For the task sending I see the progress bar fill up and then wait for 60 seconds. After 60 seconds I get a timeout and the following error message appears in the tab ‘Errors’ in Outlook Express (translated from Dutch) : ‘The server disconnected unexpectedly. Possible causes are problems with the server, networkproblems or too long inactivity. Subject ‘Test’, Account: ‘MyAccount’, Server: ‘smtp.xxxx.xx’, Protocol: SMTP, Port: 25, Secured(SSL): No, Errornumber: 0x800CCC0F’
The computer on which I have this problem is new. I have been busy installing all my software the last couple of weeks. My previous computer is still running with mostly the same software as my new computer. On my old computer I can send and receive e-mail without a problem. I have compared the settings in Avast and Outlook but have not found any differences.
On my new computer the e-mail gets sent when I disable the provider ‘Internet Mail’ in Avast. My firewall is active at that time so the firewall is probably not the problem. The application ‘ashMaiSv.exe’ is granted complete access to the Internet by the firewall.
I have checked the port-numbers in the tab ‘Redirect’ when you press the button ‘Customize’ at the provider ‘Internet Mail’. It contains the standard ports : POP 110 , SMTP 25 , IMAP 143 , NNTP 119.
In the tab ‘Advanced’ of my account in Outlook Express the standard portnumbers are shown too : SMTP 25 , POP3 110.
In the tab ‘Servers’ of my account in Outlook Express there is no tick for the option ‘Verification is needed for this server’. There is also no tick here on my old computer.
Testing after the first post
When I disable ‘Scan outbound mail’ in the tab SMTP for the and the provider stays activated I can send an e-mail. As soon as I enable ‘Scan outbound mail’ the outgoing e-mail is being blocked.
When I remove the tick before ‘Insert note into clean message’ in the tab SMTP for the provider ‘Internet Mail’ the e-mail gets sent. So there is possibly a problem when attaching this note. However when I tick the note on my old computer the e-mail gets sent. And I receive the e-mail on my new computer. The note (sent on my old computer!) is as follows :

I’m beginning to suspect corruption in Outlook Express on my new computer.
Question
Can someone give me some clues on how to find the source of this problem?
