I have tried to send email with the exact same code as in pg 318. I have a gmail account which is also setup in Outlook. When sending the email, got error message:
No connection could be made because the target machine actively refused it 74.125.157.109:587
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 74.125.157.109:587

Hi there,

Can you post the code and configuration you're using?

Windows XP

Code:
Web.config
<system.net>
<mailSettings>
<!-- <smtp deliveryMethod="Network" from="[email protected]">
<network
enableSsl="true"
port="587"
userName="[email protected]"
password="mypassword"
host="smtp.gmail.com"/>
</smtp> -->
<smtp deliveryMethod="SpecifiedPickupDirectory" from ="[email protected]">
<specifiedPickupDirectory pickupDirectoryLocation="D:\Training\TempMail" />
</smtp>
</mailSettings>
</system.net>

Note: when I use "deliveryMethod="SpecifiedPickupDirectory"", it works.

And how does the code you're using look?

I just copied your code (the gmail version) into my Planet Wrox sample project, changed the user name and password and ran Email.aspx from the Demos folder. Within seconds I receieved the test message. So, conceptually, the configuration code is OK.

Cheers,

Imar

I try it again, this is the message:

Yes, I know, but you already posted that same error message. What I need to look at is the code that causes this exception.

Are you running Anti Virus software or a firewall on your machine? Can you try disabling it temporarily?

If it keeps failing, just use the SpecifiedPickupDirectory for local development as it works equally OK.

Cheers,

Imar

Hi Imar,

Thanks a lot, I disable my antivirus and it does work.
