## generate self-signed ssl certificate
You can easily generate a self-signed SSL certificate by using the following command:
docker run -ti --rm -v "$(pwd)"/postfix/ssl:/ssl -h mail.my-domain.com -t tvial/docker-mailserver generate-ssl-certificate
# Press enter
# Enter a password when needed
# Fill information like Country, Organisation name
# Fill "my-domain.com" as FQDN for CA, and "mail.my-domain.com" for the certificate.
# They HAVE to be different, otherwise you'll get a `TXT_DB error number 2`
# Don't fill extras
# Enter same password when needed
# Sign the certificate? [y/n]:y
# 1 out of 1 certificate requests certified, commit? [y/n]y
# will generate:
# postfix/ssl/mail.my-domain.com-key.pem (used in postfix)
# postfix/ssl/mail.my-domain.com-req.pem (only used to generate other files)
# postfix/ssl/mail.my-domain.com-cert.pem (used in postfix)
# postfix/ssl/mail.my-domain.com-combined.pem (used in courier)
# postfix/ssl/demoCA/cacert.pem (certificate authority)
Note that the certificate will be generate for the container `fqdn`, that is passed as `-h` argument.
Check the following page for more information regarding [postfix and SSL/TLS configuration](http://www.mad-hacking.net/documentation/linux/applications/mail/using-ssl-tls-postfix-courier.xml).
## configure ssl certificate (convention over configuration)
If a matching certificate (files listed above) is found in `postfix/ssl`, it will be automatically setup in postfix and courier-imap-ssl. You just have to place them in `postfix/ssl` folder.
