Docker Container for SMTP Relay

SMTP Relay service allows you to use an external SMTP server to send your mails through. After many frustrating hours of working with several SMTP Relay Docker Images, I finally found the one that works.


Configuration is very easy; Sample Run script

docker run \
--name name\
-d \
--restart=always \
-p localport:25 \
-e "MAIL_RELAY_HOST=smtpserver" \
-e "MAIL_RELAY_PORT=port#" \
-e "MAIL_RELAY_USER=user" \
-e "MAIL_RELAY_PASS=post" \

After this you will have a running Docker container that will relay all your emails to the “smtpserver” you have set.
