SpamCop FAQ : SpamCop Parsing and Reporting Service : How do I get my email program to reveal the full, unmodified email? :
Sylpheed is an email client for Linux, BSD and Unix systems. Sylpheed offers three ways to view the full source code of messages:

• Select the email
• Right click and mouse-over "View"
• Select "Source" from the popup menu

or....

• Select the email
• Left click on the "View" menu
• Select "View Source"

or....

• Select the email
• Press Ctrl-U (default keymap setting)

To use the Email Submission System with Sylpheed, it is necessary to use a command line mailer such as Blat.

Using blat, you automatically send spam reports from the command line:

blat %1 -subject "spam report" -to submit.YourSpamCopCode@spam.spamcop.net

where the %1 variable is replaced by the Sylpheed message number (an ordinary text file).
