Subject: Email from Webform ending up in spam folder

I wonder if someone could help me out here.

My webform generates a "thank you" email that is ending up in spam folders.
However the exact same email when sent from an email client (e.g., Outlook
Express) is not flagged as spam.

I tried sending them to my Yahoo inbox. Here are the headers from emails.
The bodies are exactly the same and are short "thank you" notes.  Names and
IP addresses have been changed, however none of the IPs are in any spam
databases.

Thanks for any help.
