Mailing lists are an important means of communication among users and
developers of OpenBSD.
With the exception of announce, the lists are not moderated.
We deliberately restrict the number of different mailing lists.
This helps reduce the amount of cross-posting and makes sure that
the information gets distributed to a wide audience.
Be considerate of other subscribers on the mailing lists.
- Plain text, 72 characters per line
- Many subscribers and developers read their mail on text-based mailers
emacs or mutt, and they often find HTML-formatted messages (or lines that
stretch beyond 72 characters) unreadable.
Most OpenBSD mailing lists strip messages of MIME content before sending
them out to the rest of the list.
If you don't use plain text, your messages will be reformatted or, if they
cannot be reformatted, summarily rejected.
The only mailing lists that allow file attachments are the bugs,
ports and tech lists.
They will be removed from messages on the others.
- Do your homework before you post
- If you have an installation question, make sure that you have read
the relevant documents, such as the INSTALL.* text files in the
installation directories, the FAQ and the
relevant man pages (start with
Also check the mailing list archives.
We want to help, but we wouldn't want to deprive you of a valuable
learning experience, and no one wants to see the same question on the
lists for the fifth time in a month.
- Include a useful Subject line
- Messages with an empty Subject will get bounced to the list manager and
will take longer to show up.
Including a relevant Subject in the message
will ensure that more people actually read what you've written.
Also, avoid Subject lines with excessive capitalization.
"Help!" or "I can't get it to work!" are not useful subject lines.
Do not change the subject line while on the same topic.
YOU may know what it is regarding, the rest of us who get several hundred
messages a day will have no idea.
- Trim your signature
- Keep the signature lines at the bottom of your mail to a reasonable
PGP signatures and those automatic address cards are merely annoying and
are stripped out.
Legal disclaimers and advisories are also very annoying, and inappropriate
for public mailing lists.
- Stay on topic
- Please keep the subject of the post relevant to users of OpenBSD.
- Include important information
- Don't waste everyone's time with a hopelessly incomplete question.
No one other than you has the information needed to resolve your
problem, it is better to provide more information than needed than not
All questions should include at least the
version of OpenBSD.
Any hardware-related questions should mention the platform (i386, amd64,
etc.) and provide a full
Hardware model numbers, unfortunately, don't indicate much about the
actual content of a particular machine or accessory, and are useless to
anyone who doesn't have that exact machine sitting where they can easily
The dmesg(8) output tells us exactly what is IN your machine, not what
stickers are on the outside.
- Respect differences in opinion and philosophy
- Intelligent people may look at the same set of facts and come to very
Repeating the same points that didn't convince someone previously rarely
changes their mind, and irritates all the other readers.
The OpenBSD lists use spamd(8)
and SpamAssassin to keep down the
spam volume, but things do sneak through from time to time -- deal with it.
In addition, the list server also has regex-based rules to reject emails
based on some common spam and virus telltales.
If you get spam through one of the OpenBSD mailing lists, you don't need to
send a copy to the list owner -- chances are he's already seen it.
Also, please do not submit spam received through the
mailing lists to spamcop,
as this will result in the list server being added to their RBL.
Complaining about and commenting upon spam on the list proper is
counter-productive, as it generates more traffic than the spam itself.
Note that if you are sending mail from a dynamic IP address, you
will probably not be able to post to the mailing lists.
In this case, you should use a smart host mail configuration
that utilizes your ISP's mail server.
See the examples in
smtpd.conf(5) for how
to do this.
General interest lists
These lists are of interest to most users of OpenBSD.
- User questions and answers, general questions.
This is the most active list.
Please, read the FAQ and the installation
documents, and see how to report a problem
- Promoting the use of OpenBSD.
- Announcements and security advisories.
- Discussions about using and contributing to the ports tree.
These lists are for technical discussions of aspects of OpenBSD.
They are NOT for beginning or average users, they are not for problem
reporting (unless you are including a good fix) and they are not for
If you have any question about if a message should be posted to any of
these lists, it probably should not.
Use misc instead.
- Bug reports as sent in via
and follow-up discussions.
- Discussion of technical topics for OpenBSD developers and advanced
This is not a "tech support" forum; do not use it as such.
OpenBSD developers will often make patches to implement new features
and other important changes available for public testing through this
- Technical discussion about native and portable LibreSSL.
Users of LibreSSL on any operating system are welcome to participate.
Patches for the native LibreSSL should be sent to this list and use
OpenBSD's CVS tree or a git mirror of it.
Patches for the portable bits should be pull requests on
These private lists are for reporting vulnerabilities to the OpenBSD team.
- Report vulnerabilities related to OpenSSL or LibreSSL to the core
- Report vulnerabilities related to OpenBSD.
These lists are focused on user issues and development on individual

- OpenBSD/macppc and other PowerPC porting efforts

CVS changes mailing lists
Every time a developer commits a change to the OpenBSD CVS tree, a message
is mailed out to all the subscribers of these lists, containing the commit
- Automated mail of CVS source tree changes in the src, xenocara and www
- Automated mail of CVS source tree changes in the ports repository.
Announcements and discussion relating to mirrors of OpenBSD.
- This is a moderated list used solely for important announcements
to operators of OpenBSD mirrors.

Managing list membership via Majordomo
If you want to be sent a complete list with all mailing lists available
at openbsd.org, send the command lists in the body of
a message to
To subscribe to a given list, send mail to
with a message body of "subscribe mailing-list-name" (where
mailing-list-name is the name of your preferred list).
For further assistance, send a message body of "help" to
and you will receive a reply outlining all your options.
Your domain must resolve properly or the mail will not go through!
Managing list membership via the web
Your membership to the OpenBSD mailing lists can also be managed via
a web interface at lists.openbsd.org.
Mailing list tricks
There are a number of very useful options that can be selected, either
by the web interface or through
You can change your email address without having to unsubscribe and
resubscribe, temporarily disable your message delivery for a few days
while you go on vacation and much more.
The user is invited to spend some time reading through the options, available
by sending Majordomo a message
containing "help" as the body text, or through the "Help" tab of the
As an example, if you were going on vacation for two weeks and didn't
wish to come back to several thousand emails, you can disable message
delivery by the mail server for the time of your vacation and have
delivery automatically resume upon your scheduled return using the command:
This will suspend your subscription to all mailing lists for 14 days

If you would prefer to see a "digest" (a consolidated listing of all the
messages for a time period), rather than getting messages individually
in "real-time" form, you can use the commands:

Yes, multiple commands can be placed in one Majordomo email.

Other Mailing Lists
The fine folks at squish.net run
mailing lists with daily and weekly digests of the OpenBSD source-changes
and ports-changes mailing list.
This is handy for those who don't like the typically high volume of these lists.
