Self-Hosted Email
Note
Outbound Email
Self-hosted Sentry ships with a built-in outgoing SMTP server powered by exim4. The default configuration is set to use this server. All you need to do is to set a valid address for mail.from setting in config.yml and the FQDN of your Sentry instance for SENTRY_MAIL_HOST in .env. Keep in mind that if you start sending too many emails to public addresses, your new server may get marked as a spammer and banned.
If you want to use an external SMTP server you can set the relevant mail.* settings in config.yml file and ignore the built-in SMTP server. Refer to our email service documentation for all the details on what each setting means and does. If your MX records usually resolve to internal private network mail handlers, see this ticket for some pointers.
Warning
mail settings through the web interface, you will need to also comment out the mail.host: 'smtp' default in your config.yml in order for your desired settings to be picked up.Inbound Email
Sentry has very limited inbound mail support through Mailgun. You can find all the information regarding how to set this up over at our inbound email service documentation.
