SimpleLogin | Protect your online identity with email alias
Your email address is your online identity. When you use the same email address everywhere, you can be easily tracked. More information on https://simplelogin.io
This README contains instructions on how to self host SimpleLogin.
Once you have your own SimpleLogin instance running, you can change the API URL
in SimpleLogin's Chrome/Firefox extension, Android/iOS app to your server.
SimpleLogin roadmap is at https://github.com/simple-login/app/projects/1 and our forum at https://github.com/simple-login/app/discussions, feel free to submit new ideas or vote on features.
Prerequisites
-
a Linux server (either a VM or dedicated server). This doc shows the setup for Ubuntu 18.04 LTS but the steps could be adapted for other popular Linux distributions. As most of components run as Docker container and Docker can be a bit heavy, having at least 2 GB of RAM is recommended. The server needs to have the port 25 (email), 80, 443 (for the webapp), 22 (so you can ssh into it) open.
-
a domain that you can config the DNS. It could be a sub-domain. In the rest of the doc, let's say it's
mydomain.com
for the email andapp.mydomain.com
for SimpleLogin webapp. Please make sure to replace these values by your domain name whenever they appear in the doc. A trick we use is to download this README file on your computer and replace allmydomain.com
occurrences by your domain.
Except for the DNS setup that is usually done on your domain registrar interface, all the below steps are to be done on your server. The commands are to run with bash
(or any bash-compatible shell like zsh
) being the shell. If you use other shells like fish
, please make sure to adapt the commands.
Some utility packages
These packages are used to verify the setup. Install them by:
sudo apt update && sudo apt install -y dnsutils
Create a directory to store SimpleLogin data:
mkdir sl
mkdir sl/pgp # to store PGP key
mkdir sl/db # to store database
mkdir sl/upload # to store quarantine emails
DKIM
From Wikipedia https://en.wikipedia.org/wiki/DomainKeys_Identified_Mail
DomainKeys Identified Mail (DKIM) is an email authentication method designed to detect forged sender addresses in emails (email spoofing), a technique often used in phishing and email spam.
Setting up DKIM is highly recommended to reduce the chance your emails ending up in the recipient's Spam folder.
First you need to generate a private and public key for DKIM:
openssl genrsa -out dkim.key 1024
openssl rsa -in dkim.key -pubout -out dkim.pub.key
You will need the files dkim.key
and dkim.pub.key
for the next steps.
For email gurus, we have chosen 1024 key length instead of 2048 for DNS simplicity as some registrars don't play well with long TXT record.
DNS
Please note that DNS changes could take up to 24 hours to propagate. In practice, it's a lot faster though (~1 minute or so in our test). In DNS setup, we usually use domain with a trailing dot (.
) at the end to to force using absolute domain.
MX record
Create a MX record that points mydomain.com.
to app.mydomain.com.
with priority 10.
To verify if the DNS works, the following command
dig @1.1.1.1 mydomain.com mx
should return:
mydomain.com. 3600 IN MX 10 app.mydomain.com.
A record
An A record that points app.mydomain.com.
to your server IP.
If you are using CloudFlare, we recommend to disable the "Proxy" option.
To verify, the following command
dig @1.1.1.1 app.mydomain.com a
should return your server IP.
DKIM
Set up DKIM by adding a TXT record for dkim._domainkey.mydomain.com.
with the following value:
v=DKIM1; k=rsa; p=PUBLIC_KEY
with PUBLIC_KEY
being your dkim.pub.key
but
- remove the
-----BEGIN PUBLIC KEY-----
and-----END PUBLIC KEY-----
- join all the lines on a single line.
For example, if your dkim.pub.key
is
-----BEGIN PUBLIC KEY-----
ab
cd
ef
gh
-----END PUBLIC KEY-----
then the PUBLIC_KEY
would be abcdefgh
.
You can get the PUBLIC_KEY
by running this command:
sed "s/-----BEGIN PUBLIC KEY-----/v=DKIM1; k=rsa; p=/g" $(pwd)/dkim.pub.key | sed 's/-----END PUBLIC KEY-----//g' |tr -d '\n' | awk 1
To verify, the following command
dig @1.1.1.1 dkim._domainkey.mydomain.com txt
should return the above value.
SPF
From Wikipedia https://en.wikipedia.org/wiki/Sender_Policy_Framework
Sender Policy Framework (SPF) is an email authentication method designed to detect forging sender addresses during the delivery of the email
Similar to DKIM, setting up SPF is highly recommended.
Add a TXT record for mydomain.com.
with the value:
v=spf1 mx ~all
What it means is only your server can send email with @mydomain.com
domain.
To verify, the following command
dig @1.1.1.1 mydomain.com txt
should return the above value.
DMARC
From Wikipedia https://en.wikipedia.org/wiki/DMARC
It (DMARC) is designed to give email domain owners the ability to protect their domain from unauthorized use, commonly known as email spoofing
Setting up DMARC is also recommended.
Add a TXT record for _dmarc.mydomain.com.
with the following value
v=DMARC1; p=quarantine; adkim=r; aspf=r
This is a relaxed
DMARC policy. You can also use a more strict policy with v=DMARC1; p=reject; adkim=s; aspf=s
value.
To verify, the following command
dig @1.1.1.1 _dmarc.mydomain.com txt
should return the set value.
For more information on DMARC, please consult https://tools.ietf.org/html/rfc7489
Docker
Now the boring DNS stuffs are done, let's do something more fun!
If you don't already have Docker installed on your server, please follow the steps on Docker CE for Ubuntu to install Docker.
You can also install Docker using the docker-install script which is
curl -fsSL https://get.docker.com | sh
Prepare the Docker network
This Docker network will be used by the other Docker containers run in the next steps. Later, we will setup Postfix to authorize this network.
sudo docker network create -d bridge \
--subnet=10.0.0.0/24 \
--gateway=10.0.0.1 \
sl-network
Postgres
This section creates a Postgres database using Docker.
If you already have a Postgres database in use, you can skip this section and just copy the database configuration (i.e. host, port, username, password, database name) to use in the next sections.
Run a Postgres Docker container as your Postgres database server. Make sure to replace myuser
and mypassword
with something more secret.
docker run -d \
--name sl-db \
-e POSTGRES_PASSWORD=mypassword \
-e POSTGRES_USER=myuser \
-e POSTGRES_DB=simplelogin \
-p 127.0.0.1:5432:5432 \
-v $(pwd)/sl/db:/var/lib/postgresql/data \
--restart always \
--network="sl-network" \
postgres:12.1
To test whether the database operates correctly or not, run the following command:
docker exec -it sl-db psql -U myuser simplelogin
you should be logged in the postgres console. Type exit
to exit postgres console.
Postfix
Install postfix
and postfix-pgsql
. The latter is used to connect Postfix and the Postgres database in the next steps.
sudo apt-get install -y postfix postfix-pgsql -y
Choose "Internet Site" in Postfix installation window then keep using the proposed value as System mail name in the next window.
Replace /etc/postfix/main.cf
with the following content. Make sure to replace mydomain.com
by your domain.
# POSTFIX config file, adapted for SimpleLogin
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = no
# See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on
# fresh installs.
compatibility_level = 2
# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtp_tls_security_level = may
smtpd_tls_security_level = may
# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.
alias_maps = hash:/etc/aliases
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 10.0.0.0/24
# Set your domain here
mydestination =
myhostname = app.mydomain.com
mydomain = mydomain.com
myorigin = mydomain.com
relay_domains = pgsql:/etc/postfix/pgsql-relay-domains.cf
transport_maps = pgsql:/etc/postfix/pgsql-transport-maps.cf
# HELO restrictions
smtpd_delay_reject = yes
smtpd_helo_required = yes
smtpd_helo_restrictions =
permit_mynetworks,
reject_non_fqdn_helo_hostname,
reject_invalid_helo_hostname,
permit
# Sender restrictions:
smtpd_sender_restrictions =
permit_mynetworks,
reject_non_fqdn_sender,
reject_unknown_sender_domain,
permit
# Recipient restrictions:
smtpd_recipient_restrictions =
reject_unauth_pipelining,
reject_non_fqdn_recipient,
reject_unknown_recipient_domain,
permit_mynetworks,
reject_unauth_destination,
reject_rbl_client zen.spamhaus.org,
reject_rbl_client bl.spamcop.net,
permit
Create the /etc/postfix/pgsql-relay-domains.cf
file with the following content.
Make sure that the database config is correctly set, replace mydomain.com
with your domain, update 'myuser' and 'mypassword' with your postgres credentials.
# postgres config
hosts = localhost
user = myuser
password = mypassword
dbname = simplelogin
query = SELECT domain FROM custom_domain WHERE domain='%s' AND verified=true
UNION SELECT '%s' WHERE '%s' = 'mydomain.com' LIMIT 1;
Create the /etc/postfix/pgsql-transport-maps.cf
file with the following content.
Again, make sure that the database config is correctly set, replace mydomain.com
with your domain, update 'myuser' and 'mypassword' with your postgres credentials.
# postgres config
hosts = localhost
user = myuser
password = mypassword
dbname = simplelogin
# forward to smtp:127.0.0.1:20381 for custom domain AND email domain
query = SELECT 'smtp:127.0.0.1:20381' FROM custom_domain WHERE domain = '%s' AND verified=true
UNION SELECT 'smtp:127.0.0.1:20381' WHERE '%s' = 'mydomain.com' LIMIT 1;
Finally, restart Postfix
sudo systemctl restart postfix
Run SimpleLogin Docker containers
To run SimpleLogin, you need a config file at $(pwd)/simplelogin.env
. Below is an example that you can use right away, make sure to
- replace
mydomain.com
by your domain, - set
FLASK_SECRET
to a secret string, - update 'myuser' and 'mypassword' with your database credentials used in previous step.
All possible parameters can be found in config example. Some are optional and are commented out by default. Some have "dummy" values, fill them up if you want to enable these features (Paddle, AWS, etc).
# WebApp URL
URL=http://app.mydomain.com
# domain used to create alias
EMAIL_DOMAIN=mydomain.com
# transactional email is sent from this email address
SUPPORT_EMAIL=support@mydomain.com
# custom domain needs to point to these MX servers
EMAIL_SERVERS_WITH_PRIORITY=[(10, "app.mydomain.com.")]
# By default, new aliases must end with ".{random_word}". This is to avoid a person taking all "nice" aliases.
# this option doesn't make sense in self-hosted. Set this variable to disable this option.
DISABLE_ALIAS_SUFFIX=1
# the DKIM private key used to compute DKIM-Signature
DKIM_PRIVATE_KEY_PATH=/dkim.key
# DB Connection
DB_URI=postgresql://myuser:mypassword@sl-db:5432/simplelogin
FLASK_SECRET=put_something_secret_here
GNUPGHOME=/sl/pgp
LOCAL_FILE_UPLOAD=1
POSTFIX_SERVER=10.0.0.1
Before running the webapp, you need to prepare the database by running the migration:
docker run --rm \
--name sl-migration \
-v $(pwd)/sl:/sl \
-v $(pwd)/sl/upload:/code/static/upload \
-v $(pwd)/dkim.key:/dkim.key \
-v $(pwd)/dkim.pub.key:/dkim.pub.key \
-v $(pwd)/simplelogin.env:/code/.env \
--network="sl-network" \
simplelogin/app:3.4.0 flask db upgrade
This command could take a while to download the simplelogin/app
docker image.
Init data
docker run --rm \
--name sl-init \
-v $(pwd)/sl:/sl \
-v $(pwd)/simplelogin.env:/code/.env \
-v $(pwd)/dkim.key:/dkim.key \
-v $(pwd)/dkim.pub.key:/dkim.pub.key \
--network="sl-network" \
simplelogin/app:3.4.0 python init_app.py
Now, it's time to run the webapp
container!
docker run -d \
--name sl-app \
-v $(pwd)/sl:/sl \
-v $(pwd)/sl/upload:/code/static/upload \
-v $(pwd)/simplelogin.env:/code/.env \
-v $(pwd)/dkim.key:/dkim.key \
-v $(pwd)/dkim.pub.key:/dkim.pub.key \
-p 127.0.0.1:7777:7777 \
--restart always \
--network="sl-network" \
simplelogin/app:3.4.0
Next run the email handler
docker run -d \
--name sl-email \
-v $(pwd)/sl:/sl \
-v $(pwd)/sl/upload:/code/static/upload \
-v $(pwd)/simplelogin.env:/code/.env \
-v $(pwd)/dkim.key:/dkim.key \
-v $(pwd)/dkim.pub.key:/dkim.pub.key \
-p 127.0.0.1:20381:20381 \
--restart always \
--network="sl-network" \
simplelogin/app:3.4.0 python email_handler.py
And finally the job runner
docker run -d \
--name sl-job-runner \
-v $(pwd)/sl:/sl \
-v $(pwd)/sl/upload:/code/static/upload \
-v $(pwd)/simplelogin.env:/code/.env \
-v $(pwd)/dkim.key:/dkim.key \
-v $(pwd)/dkim.pub.key:/dkim.pub.key \
--restart always \
--network="sl-network" \
simplelogin/app:3.4.0 python job_runner.py
Nginx
Install Nginx and make sure to replace mydomain.com
by your domain
sudo apt-get install -y nginx
Then, create /etc/nginx/sites-enabled/simplelogin
with the following lines:
server {
server_name app.mydomain.com;
location / {
proxy_pass http://localhost:7777;
}
}
Reload Nginx with the command below
sudo systemctl reload nginx
At this step, you should also setup the SSL for Nginx. Here's our guide how.
Enjoy!
If all the above steps are successful, open http://app.mydomain.com/ and create your first account!
By default, new accounts are not premium so don't have unlimited alias. To make your account premium, please go to the database, table "users" and set "lifetime" column to "1" or "TRUE":
docker exec -it sl-db psql -U myuser simplelogin
UPDATE users SET lifetime = TRUE;
exit
Once you've created all your desired login accounts, add these lines to /simplelogin.env
to disable further registrations:
DISABLE_REGISTRATION=1
DISABLE_ONBOARDING=true
Then restart the web app to apply: docker restart sl-app
