Spam problem


How to send a Spam or Ham sample to us
To make sure that spam and ham submissions can be processed as quickly as possible we kindly ask you to follow these guidelines.

Submitting Spam Samples to F-Secure

If you have messages which were incorrectly classified by our spam scanner, we would like to recieve a copy.

There are two different scenarios and so two different submission addresses.

There are also some requirements on how to format your submission. Incorrectly formatted submissions will be discarded without notice.

Finally, there is a section about submitting "phishing" samples, i.e. messages which purport to be from your bank or some other reputable organization, but which in reality are attempts to get you to disclose your password for the legitimate service to a scammer.

Spam Submissions

Spam messages which were not identified as spam can be sent to the address spam-samples@f-secure.com as a zip attachment. See below for detailed formatting instructions.

Do not send messages which are merely unwelcome. Our policy is to accept only messages which are completely unsolicited. You should never sign up for a mailing list and then report it as spam when you no longer want to receive it. Joke messages from friends can be tiresome, too, but they're not spam.

Messages which are more than a few days old are probably not worth reporting to us any longer.

Ham Submissions

Messages which were incorrectly classified as spam can be sent to the address ham-samples@f-secure.com as a zip attachment. See below for detailed formatting instructions.

We assume no responsibility for secret information you may send us. If you send a message to us using this channel, our only guarantee is that it will not be released outside of our organization.

Do not send manipulated messages. If you feel you have to edit a message before you can send it to us, please don't send it at all.

Phishing Samples

We welcome submissions of messages which attempt to scam you into revealing your bank accounts, credit card numbers, passwords, etc. These scams are informally known as "phishing". They could be classified as spam (they are uninvited, and often sent in large volumes), but we prefer to treat them separately because of their security implications.

Please send samples of phishing messages to the address phishing-samples@f-secure.com as a zip attachment. See below for detailed formatting instructions.

Formatting Instructions

All submissions should meet the following criteria:
  • They should be sent from a valid, live email address. We need to be able to reply to you if we have questions. (Nevertheless, you should not expect any response in the normal case.)
  • If you include comments, please write the comments in English only. Messages in other languages may be delayed or even discarded entirely.
  • The sample(s) should be attached as a .zip file. The name of the zip file should be samples.zip and it should have no password or other extra features (internal directory structure, unrelated files, etc).
  • The sample messages should be stored as individual files in the zip archive.
  • Each message/file should be exactly as received by you, with full headers.
There are many good sites with instructions for how to obtain the full headers of an email message; one excellent example is http://helpdesk.rootsweb.com/listadmins/headersfull.html (external link).

If you use Outlook and another email client in parallel, it's probably best to use the alternate client to extract messages for submission.

Please do not create multiple submissions needlessly. If you have a few messages which you want to submit, collect them all into one .zip file and send them as a single submission. (You should of course not mix spam and ham samples in the same submission.)
