Mailman

Some suggested default setup for new Mailman list

All default setup for new Mailman list are located in /usr/lib/mailman/Mailman/Defaults.py, BUT please NEVER touch it and override by using /etc/mailman/mm_cfg.py. Here are some suggested setup for internal usage, just copy and append at the end of /etc/mailman/mm_cfg.py:

DEFAULT_ARCHIVE_PRIVATE = 1
DEFAULT_GENERIC_NONMEMBER_ACTION = 3
DEFAULT_LIST_ADVERTISED = No
DEFAULT_MAX_MESSAGE_SIZE = 0
DEFAULT_MSG_FOOTER = ""
DEFAULT_MSG_HEADER = ""
DEFAULT_REQUIRE_EXPLICIT_DESTINATION = No
DEFAULT_SUBJECT_PREFIX = ""

P.S. Someone like to have subject prefix but someone not. If most of your client are using desktop MUA, e.g. Thunderbird or Outlook, having subject prefix can simplify their filtering rules setup. Always remove header/footer message if some of your client are using legacy MUA.


IT-School HTML mail + mailman

As IT-School will send out email as encoded HTML, I need to remove the footer message (text/plain) from mailman, in order to keep overall message as HTML only (text/html).

Non-digest options / Digest options
-> Footer added to mail sent to regular list members
-> (remove all footer message)

UPDATE (20090306): After more indeed study of this problem I get this page (http://wiki.list.org/pages/viewpage.action?pageId=4030707):

4.39. HELP! Mailman is munging HTML & MIME-formatted messages before they are sent out? (problems with Mailman 2.1.x footers)
...
So, what Mailman does instead is to take the entire HTML message as sent, put that into a MIME bodypart, add another MIME bodypart for the footer, and then wrap all that up and send it out as a message that is formatted as a different kind of MIME message. Some MUAs will display the result in a fashion reasonably close to the format in which the message was submitted, and some won't. Those that have problems may result in the footer being displayed as an attachment, or worse. The same issue applies to msg_header, if any, although in this case, some MUA's may display the header as the message and the body as an attachment.
...
To solve this problem, your options are:

1. Configure Mailman to remove the msg_header/msg_footer
2. Configure Mailman to strip all HTML and MIME formatting and send out all
messages as text-only (text/plain)
3. Get everyone to change the MUA they use to one that is more HTML/MIME-aware
4. Live with the problem
...
Remember - this is not an HTML problem. This is a MIME and MIME/HTML problem. All MIME-formatted messages may have the same problem.

Ok fine... Again the problem of the legacy IT-School MUA engine... As it can't display multipart message correctly, I need to remove all footer message from mailman lists.


Exim4 + Mailman + Apache2 on Debian etch mini-HOWTO

This is just a very fast and rough simple guideline for setting up Mailman + Exim4 based on Debian etch. For sure that we will also configure Apache2 for Mailman web interface. Not much detail will be mentioned, please refer to corresponding document if you hope to understand more. Debian also come with a handy guideline from /usr/share/doc/mailman/README.Exim4.Debian, so you should have a look with it before follow this guideline :)
