IEEE 802.1 Email Lists
Sending to the Lists

Skip to content
Updated May 14, 2011

Before posting email to either list, you should understand the restrictions on format, content, and message size.


A non-blank subject line is required. For ballot responses, the correct subject is specified in the ballot announcement.

The preferred message format is plain text. HTML is discarded if present, and the message rejected if it lacks plaintext.

Before sending email with attachments, please read the comments on attachment types (below) and the restrictions on total message size.

Do not use “return receipt requested” on mail to the list. If someone else does use it, please do not return a receipt.

Replies to list email go to the originator, not to the list. If you use “Reply All” to circumvent this, make sure you don't send multiple copies to the list, or extra copies to the list owner.


The preferred attachment type is Acrobat PDF. Others, though tolerated, may not be accepted or supported by all participants’ systems.

Because they cannot be scanned for viruses, ZIP files are to be avoided. If a file exceeds size limits, it should be posted online for download, and the location announced to the list.

Mail exceeding the size limit is automatically rejected.

Message content

Don't send "pings" or other null-content messages.

Spam is not welcome! This includes announcements of trade shows and other commercial activities, even those that have something to do with LANs or MANs, unless there's a direct and clearly stated relationship to list discussions.

Proprietary claims

Each list is an open forum; contributions are shared by all. Therefore, please ensure your email is free of:
  • any proprietary or confidential information,
  • any claims of proprietary interest, and
  • any restrictions on disseminating the contents.

As a matter of principle, participants may choose to disregard messages containing such claims or restrictions. They may be removed from email archives, and not treated as valid submissions. Consideration or discussion of the contents may be refused.

Whether or not that is done, any message sent to a list is effectively published worldwide, irretrievably. The contents may subsequently circulate anywhere in the universe, with no one but the original sender to blame. That's not a policy, just an observation of fact. If you want to control information, don't broadcast it to an open forum.

Message size limit

The lists reject messages over the maximum length, 150 KB. Large contributions should be sent to committee or task group chairs for posting on 802.1 web pages, and the document, with its URL, announced via the list. (If your document is in any format other than plain text, PDF, or a specified ballot-comment format, you might also discuss whether it should be converted.)

Encoding an email attachment expands it by a little more than one third. Therefore, the size limit for attached files is in the neighborhood of 100 KB, to allow sufficient margin for accompanying text, email headers, and MIME formatting.

If your email client attaches an HTML version, it is discarded before checking against the size limit.

Because of the virus risk, compressed (ZIP) files are not a good way to beat the limit.

Hint: Watch out for unintended attachments, especially forwarded items.

Participants' conduct

Usually, our discussions have remained free of flaming, inappropriate promotional messages, insults, and other misconduct. It was hoped that this section would remain superfluous forever, but apparently we need to state some rules.

The IEEE Acceptable Use Practices apply, but 802.1 reserves the right to enforce its own rules as well.

If your conduct is questioned or challenged, you may appeal to the list administrator for advice, or to the Working Group Chair for a ruling. In any case, do not continue the dispute, or the disputed conduct, via the list.

List access

You can send email contributions using the appropriate link below. But first, make sure you understand our restrictions on format, content, and size.

Note: List email addresses are accessible only through a scripted translation. You cannot use these links unless your browser supports and allows JavaScript version 1.2. This security restriction is necessary; the administrator apologizes and will help any participants who are inconvenienced by it.

DO NOT send list administration requests (subscribe, unsubscribe, etc.) to these addresses! For those matters, you want to communicate with the server or the list administrator, not the other subscribers.

If you send from an address that isn't subscribed, your message will not be accepted until you answer a confirmation request.

If the mail looks suspicious to our filters, it may be delayed for administrator approval. The delay can be anywhere from a few minutes to several days, but averages about half a day. All mail from nonsubscribers is automatically subject to approval delays.

In a few common error cases (such as a missing subject line), mail may be rejected immediately, without administrator review. This allows the author to correct the error and resend quickly. Senders to the list should monitor their email for rejection notices.
