DeadmanDAO Mail Server

AWS SES may be the solution: https://docs.aws.amazon.com/ses/latest/dg/lists-and-subscriptions.html

No, it doesn't have nearly the capabilities of a real mailing list system.

Mailchimp is out because it was bought for so much money that the money squeeze is going to be intense.

Other commercial providers are not significantly less risky than Mailchimp.

Mailman is robust once deployed and the initial build-out is not too painful.

DeadmanDAO Mailman Build-out

• MailingListDeadmanFirstPass (Deb 10, Mailman 3: installed Apache and Certbot before Mailman, which made it hard to deploy the Mailman web console)
• MailingListDeadmanSecondPass (Deb 10, Mailman 3: had trouble getting the Snap/PIP/VirtualEnv version of Mailman to let me in as an administrator)
• MailingListDeadmanThirdPass Deb 9, Mailman 2, had trouble getting the Mailman executables to execute as cgi's.
• Fourth Pass: Deb 10, Mailman 2.

Create Instance

Interserver Web Interface

1. go to interserver
2. create an instance
   1. Single Slice ($6/mo at this time)
   2. Debian 9 (Deb 9 has Mailman 2, Deb 10 has Mailman 3)
   3. KVM
3. set reverse DNS to diffie.deadmandao.com
4. Note the IP address

Update to Latest

Log in root@ip.address using password you provided

apt-get update
apt-get -y upgrade
apt-get -y dist-upgrade # if needed
reboot

Add User Account

Log in root@ip.address

apt-get -y install sudo
adduser bob
usermod -G sudo bob
exit

Log in to bob@ip.address

Set SPF

sudo apt-get install net-tools
sudo ifconfig

That'll give you the ip4 and ip6 addresses, which go into the DNS text record:

• v=spf1 ip4:66.23.226.216 ip6:fe80::216:3eff:fe24:10e1 -all

Set Other DNS

• A Record, diffie, 66.23.226.216
• A Record, @, 66.23.226.216
• CNAME Record, www, diffie.deadmandao.com
• CNAME Record, mail, diffie.deadmandao.com
• TXT Record, diffe, v=spf1 ip4:66.23.226.216 ip6:fe80::216:3eff:fe24:10e1 -all
• MX Record, deadmandao.com, mail.deadmandao.com, 10

Set Hostname

sudo apt-get install emacs-nox
sudo emacs -nw /etc/hostname
> diffie
sudo emacs -nw /etc/hosts
> 66.23.226.216	diffie.deadmandao.com diffie
sudo reboot

Log in to bob@diffie.deadmandao.com

hostname
hostname --all-fqdn
dnsdomainname

SMTP Server

sudo apt-get install postfix

• Internet Site
• deadmandao.com is the host domain
• send a test email

echo "Subject: sendmail test" | /usr/sbin/sendmail -v emailaddress

Had trouble with IPv6 in Debian 9 ("Network is unreachable"). Used the following in main.cf to switch to IPv4 only.

# inet_protocols = all
inet_protocols = ipv4

Mailman Install

install

sudo apt install mailman

init list

sudo newlist
> roundtable

It tells me that I should put the following in aliases:

## roundtable mailing list
roundtable:              "|/var/lib/mailman/mail/mailman post roundtable"
roundtable-admin:        "|/var/lib/mailman/mail/mailman admin roundtable"
roundtable-bounces:      "|/var/lib/mailman/mail/mailman bounces roundtable"
roundtable-confirm:      "|/var/lib/mailman/mail/mailman confirm roundtable"
roundtable-join:         "|/var/lib/mailman/mail/mailman join roundtable"
roundtable-leave:        "|/var/lib/mailman/mail/mailman leave roundtable"
roundtable-owner:        "|/var/lib/mailman/mail/mailman owner roundtable"
roundtable-request:      "|/var/lib/mailman/mail/mailman request roundtable"
roundtable-subscribe:    "|/var/lib/mailman/mail/mailman subscribe roundtable"
roundtable-unsubscribe:  "|/var/lib/mailman/mail/mailman unsubscribe roundtable"

Enter the name of the list: test
Enter the email of the person running the list: bob@traxel.com
Initial test password: 
To finish creating your mailing list, you must edit your /etc/aliases (or
equivalent) file by adding the following lines, and possibly running the
`newaliases' program:

## test mailing list
test:              "|/var/lib/mailman/mail/mailman post test"
test-admin:        "|/var/lib/mailman/mail/mailman admin test"
test-bounces:      "|/var/lib/mailman/mail/mailman bounces test"
test-confirm:      "|/var/lib/mailman/mail/mailman confirm test"
test-join:         "|/var/lib/mailman/mail/mailman join test"
test-leave:        "|/var/lib/mailman/mail/mailman leave test"
test-owner:        "|/var/lib/mailman/mail/mailman owner test"
test-request:      "|/var/lib/mailman/mail/mailman request test"
test-subscribe:    "|/var/lib/mailman/mail/mailman subscribe test"
test-unsubscribe:  "|/var/lib/mailman/mail/mailman unsubscribe test"
