How to relay all local mail through external SMTP relay?

Ok, I got the ASP mailer working, but now the Mail Server won't recieve the emails. Any ideas?

• I added theSendUsind schema and the port, username, and password, and the ASP mailer works with no errors. But the email never makes it to the inbox. It's a contact form on the website that sends the users' information to the company owner, who'sMail Server is the one the contact for uses to send the email. Any idea why it won't recieve the email? Is there another sort of authentication I need besides the ones listed above? The email addresses are [email protected], but the mail server is smtp.wdweb.com. Could it be because the domain name and mail server are different? I've read that some servers won't relay a mail unless the from and server domain are the same. But wouldn't this still suplly me with an error???

• Answer:

  spam filters often catch emails that come from different domains than the actual sending agent. You may also need to check your firewall settings on the SMTP server to make sure communications aren't being blocked.
