HOWTO - Send SPAM samples to ETRN

If you have suspect e-mail content that you would us like to inspect, but, you feel that the content would likely be considered SPAM, here are some methods to consider: (provided in order of preference)

  • Provide us with the URL to the e-mail in Mailguard.
  • Forward the e-mail as an attachment  (not inline) to headers@spamtrap.ETRN.com. The e-mail must be forwarded as an attachment as forwarding the e-mail inline causes all of the useful header information to be lost. When you forward your e-mail, the system will appear to reject the e-mail and will provide you with an ID number that looks like this: ID: 27AF2AEE-C727-4328-955B-A12A0FA13A03.1. Please provide us  (either via the linked contact form, or via e-mail to service@etrn.com) with the ID number.
  • Upload the e-mail here: Upload Spam Sample.
    Please note: you will not receive a response from us when using this method. You must upload the full contents of the e-mail. If you e-mail is in .eml format, please upload the e-mail in that format. If you use Outlook and have a single sample to upload, select the desired e-mail in Outlook and choose File => Save As. Then upload the resulting .msg file using the link above.
    If you use Outlook and have multiple samples, we recommend the following:
  • Provide us with the full headers of the e-mail. If the e-mail has been received recently enough, that may be enough information to locate the e-mail if is still cached in Mailguard.
  • Provide us with the date and time you received the e-mail(s) along with any header information (From:, To:, etc.) that you have. This typically allows us to narrow our search to a specific set of e-mails in Mailguard and this may be enough information to locate the e-mail if is still cached in Mailguard.
  • Provide us with all of the header information (From:, Subject:, To:, etc.) that you have. This typically allows us to narrow our search to a specific set of e-mails in Mailguard and this may be enough information to locate the e-mail if is still cached in Mailguard.

Please do not forward spam e-mails directly to us. Unfortunately, when you simply forward spam to us, it may have the following effects, which are probably not what you are trying to achieve:

  1. It may make your e-mail address look like that of a spammer (as forwarding spam is pretty much the same as sending spam). As a result, it may cause your e-mail may be blocked or quarantined.
  2. In order for us to access and process your e-mail, we may have to tell the system your e-mail is not spam, thereby training the system that the spam you forwarded is not spam.
  3. Our replies to you may end up being blocked or quarantined if we don't take additional actions to prevent that from occurring.

We Answer Your Questions: FAQ

Q: What is the maximum e-mail attachment size?

A: The ETRN.com e-mail servers do not limit the size of individual e-mail attachments. The ETRN.com e-mail servers do impose a 400 MB maximum total message size limit. Individual customers can choose a smaller message size limit. We can also customize the handling of "over-sized" e-mails. Please contact us to discuss your specific needs. A couple of important facts:

1. Attachments are typically encoded in what is called Base64[1]. As a result, the actual length of MIME-compliant Base64-encoded binary data is usually about 137% of the original file size.

2. E-mails often contain both plain text and HTML components. This also increases the overall size of the e-mail.
