1. The purpose of this page

This page is intended for use in collecting recipes for different mail clients to filter W3C List Mail on the List-Id header, please add additional client configurations. Many mail clients are capable of filtering on more that To, From and Subject headers and W3C does not do subject tagging. In addition to filtering on List-Id you may want to also check the To and Cc for list aliases in you want messages that are addressed to you and a list to filter to the same mailbox as they would have had no list server processing prior to delivery to you.

2. Clients

2.1. Apple Mail

There are two options:

1. Using rules, you can modify the header list and List-Id and then add filtering on <www-html.w3.org> to a specific folder.

2. Using smart folders, you can't use list-id, you have to use the "recipients" = www-html@w3.org

2.2. Eudora

This is also described in the "Detailed Filters with the Filters Windows" section of Eudora's user manual.

Open the Tools menu and select Filters. This allows for more advanced filtering options than the simpler filtering interface when trying to create a filter on an individual message.

Select Incoming and in the "Header" form, type: List-Id

then in the form after the "Contains", type (for example): <www-html.w3.org>

in Actions, select "Transfer To" then pull down the right mailbox in Transfer in the menu or create a new one.

lastly click New button.

You can also use this filtering to do subject tagging if that is desired and shown in the following screenshot.

2.3. Exim Filtering

If you use Exim filters (ie: .forward files) on your mail server to filter your incoming mail and want to save each mailing list to a separate folder (similar to the Procmail technique explained above).

The following pattern will filter each mailing list your are subscribed to to it's own mailbox: 

# Filter mailing list emails based on the List-Id: header
if $h_List-Id: matches "\\N<([a-z0-9-]+)"
then
  save $home/Mail/$1/
  finish
endif

Same filter but if you use Maildir instead of the mailbox format: 

# Filter mailing list emails based on the List-Id: header
if $h_List-Id: matches "\\N<([a-z0-9-]+)"
then
  save $home/Maildir/.$1/
  finish
endif

2.4. GMail

The "Has the words" field in GMail's filter editor apparently supports a keyword called listid.

Here is an example for filtering the www-html@w3.org mailing list. 

List-Id: <www-html.w3.org>

Simply enter the following in Gmail's "Has the words" field: 

listid: www-html.w3.org

2.5. Gnus

One way to do this in Gnus is with nnmail-split-methods. 

 nnmail-split-methods 
 '(
   ("mail.example.com" "^List-Id: .*www-html.w3.org")
;or if you want to filter things even addressed to me that also is sent to list to same mailbox use the following instead
   ("mail.example.com" "^\\(to\\|cc\\|list-id\\): .*www-html.w3\.org")
;additional filters here...
 )

2.6. Mutt

Mutt has advanced mailing list handling features which are, however, not based on the List-Id header: Rather, mutt evaluates the visible recipient addresses of a message.

If you are subscribed to a mailing list, e.g., <www-html@w3.org>, use this configuration directive to tell mutt about it: 

  subscribe www-html@w3.org

With the default configuration, this will cause the index to override the sender's name with information about the mailing list that you received the message from. If that is undesired, the index_format configuration variable can be adjusted. E.g., the following setting preserves the sender's name, and includes eventual mailing list information right before the subject header, in square brackets: 

  set   index_format="%6C %Z %{%b %d} %-18.18F (%4c) %-4.4H %?L?[%L] ?%s"

The mutt-users@mutt.org mailing list is generally a good source of advice for configuring this mail user agent. W3C participants may also contact tlr@w3.org for support; when doing so, please copy sysreq@w3.org on your message, as you might otherwise be pointed at the mutt-users list.

2.7. Outlook

In Outlook 2007, the process for creating the List-ID filter is as follows:

Choose New.

This should complete the process.

2.8. Pine

2.9. Procmail

If you or your system administrator can maintain customized procmailrc files to filter your incoming mail this is a way to do this server side which is very useful if for instance you use IMAP and read your mail from multiple clients.

The following pattern will filter each mailing list your are subscribed to to it's own mailbox. 

:0:
#remove the . below if you want www-html mailbox instead of www-html.w3.org
* ^List-Id: <\/[a-z0-9-.]+
$MATCH

The following recipe will create subject tags 

SUBJECT=`formail -xSubject:`
:0fw
#remove the . below if you want www-html tag instead of www-html.w3.org
* ^List-Id: <\/[a-z0-9-.]+
| formail -I "Subject: [$MATCH]$SUBJECT"

This pattern filters a specific list to a specific mailbox and also includes messages addressed to recipient that also is sent to list 

:0:
* ^(To|Cc|List-Id): .*www-html[@.]w3.org
www-html

2.10. Thunderbird

In Thunderbird, the process for creating the List-ID filter is as follows:

This should complete the process. You can then Close the Message Filters window.
