If you don't see your favorite test case or the preferred propagation method of your virus or spammer of the week, in the validation suite, please send us a copy of it and we'll add it.
You could try emailing the virus or spam directly to BSM Development but this is unlikely to work if the email filters are alert. Instead, an approach that obfuscates the true nature of the message should be employed. Our preferred method is to edit your mail inbox with a text editor and copy the entire message containing the virus or spam, from the first header to the last line of the MIME attachments. Save this entire message, headers and all, in a text file and then zip the text file. Attach the zipped file to the mail message that you send to us.
