GCC mailing lists

The GCC project has many mailing lists, which are archived on the web (and searchable). Please make yourself familiar with our policies before subscribing and posting to these lists.

Announcement lists:

Open lists:

Read only lists:

Historical lists (archives only, no longer in use):

To post a message, just send mail to listname@gcc.gnu.org.

Policies

Our lists have a maximum message size of 100KB, only the gcc-prs list allows for a larger maximum message size of 2MB. If your message exceeds this size, you should compress any attachments before sending it to the list.

We have a strong policy of not editing the web archives.

When posting messages, please select an appropriate list for the message and try to avoid cross posting a message to several lists.

Please refrain from sending messages in HTML, RTF or similar formats.

Please do not include or reference confidentiality notices, like:

The referring document contains privileged and confidential information. If you are not the intended recipient you must not disseminate, copy or take any action in reliance on it, and we request that you notify companyname immediately.

Such disclaimers are inappropriate for mail sent to public lists. If your company automatically adds something like this to outgoing mail, and you can't convince them to stop, you might consider using a free web-based e-mail account.

Notices like:

Any views expressed in this message are those of the individual sender, except where they are specifically stated to be the views of companyname.

are acceptable, although they are redundant; unless explicitly stated, it's assumed that no-one on these lists means to speak for their company.

Subscribing/unsubscribing

You will be able to subscribe or unsubscribe from any of the GCC mailing lists via this form:

Mailing list:
Your e-mail address:
Digest version    

If you're having trouble getting off a list, look at the List-Unsubscribe: header on a message sent to that list. It has your subscribed address included in it. Send mail to that address (omit the mailto: part) and you'll be unsubscribing yourself from that mailing list. You'll need to confirm the unsubscription, of course.

Please trust in the List-Unsubscribe: header. Every person who has said "I can't get off this list! Unsubscribe me!" has found, with enough prodding, that sending mail to the address listed in List-Unsubscribe: does the trick.

Filtering

If you want to use procmail or similar tools to process the GCC mailing lists, you can filter using the Sender: header, as well as all of the RFC2369 headers (List-Subscribe, List-Unsubscribe, List-Post, List-Archive, etc.).

For example, the following procmail rule will sort all mail from our lists into a single folder named INLIST.gcc:

:0
* ^Sender: .*-owner@gcc.gnu.org
INLIST.gcc

To filter duplicate messages due to cross-posts to multiple lists, you can use the following recipe (Use at your own risk!):

:0 Wh: msgid.lock
* ^Sender: .*-owner@gcc.gnu.org
| formail -D 8192 msgid.cache

Help

For further information on using the lists, send a blank mail to listname-help@gcc.gnu.org (but note that this won't currently work for the gcc list).

Spam blocking

To reduce spam sent to the GCC mailing lists, a handful of Realtime Blackhole Lists (RBLs) are consulted. If you're sending mail from a site that is listed in one of these RBLs, contact your site administrator about fixing your mail setup. Spammers are taking advantage of your site to relay their spam.

Note that, if you are subscribed to a mailing list at gcc.gnu.org, you will not be subject to any kind of spam blocking for that mailing list. However, if you are subscribed from one account and post from another then the posting account will be subject to spam block checking. To avoid this, you can put yourself on the "global allow" list for gcc.gnu.org by sending mail to

global-allow-subscribe-you=yourdomain.com@gcc.gnu.org

(where you=yourdomain.com translates to your email address with an "=" substituted for the "@"). This will bypass all spam checking for future submissions to the gcc.gnu.org mailing lists.

You can use this technique if you just want to be able to send email to a list without receiving any email from the list. You can also give yourself posting privileges just for an individual list by replacing "global" above with the name of the specific list.

To complicate the harvesting of e-mail addresses from the web archives of the GCC mailing lists, some simple transformations are done on the e-mail addresses.
