Editing CommunityData:Email (section)

== Technical Notes ==
=== Mail isn't being delivered at all! ===

On at least one occasion, Mailman became stuck and stopped delivering mail! To restart it, someone with root/sudo access on anhel needs to ssh into the sever and then run:

 $ sudo sysemctl restart mailman3 mailman3-web

This should be a harmless command to run at any point so this is a good "first resort" anytime there are mailing list problems. If that still doesn't work, contact a member of the IT Crowd.

=== Adding Lists ===

To make a new list, you first need root on anhel.communitydata.science. Run the following command:

 $ sudo -u list mailman create --notify --owner <OWNER_EMAIL1> --owner <OWNER EMAIL2> <FULL LIST EMAIL ADDRESS>

Second, visit the web interface [https://communitydata.science/mailman3/postorius Mailman web interface]. Log in with an administrator account and/or ask one of the current admins (e.g., Mako or Aaron) to make you an administrator for the mailing list you just created.

'''IMPORTANT NOTE:''' Once you set up the list, make sure you go into ''Settings → DMARC Mitigations'' and then set ''DMARK mitigation action'' to "Replace From: with list address" and then set ''DMARC Mitigate unconditionally'' to "Yes". If you skip this step, some users (especially GMail users) will silently have their mail not delivered. It's probably a good idea to edit the stuff related to the other settings too!

=== Updating/Configuring Lists ===

Most changes can simply be made on [https://communitydata.science/mailman3/postorius our mailing list website].

If you are created an email that sits behind an alias (e.g., <code>collective-purdue@</code> sits behind <code>collective@</code>) you should visit the postorius page for the list and navigate to "Settings→Message Acceptance" and edit the "Acceptable aliases" so it says something like:

 ^collective-uw@communitydata.cc
 ^collective@communitydata.cc
 ^collective@communitydata.science
 ^cdsc-all@communitydata.science

=== Adding/Updating Aliases ===

The alias file lives on anhel, at /etc/postfix/virtual. You will need root access to edit it. After editing, run

  $ sudo postmap /etc/postfix/virtual

to make it active.
