Change SMTP settings in a working forum

Hello, just a quick question. It’s possible to edit SMTP email options on a working forum?
Rebuild command will wipe all forum content (threads, posts, users, design)? in the case that I edit app.yml

Thanks.

Rebuild will not destroy any forum content as that’s stored in a persistent database file. It will stop/rebuild/start the app container, however, so your site will be down during the rebuild time.

Thank you @justindirose, if I decide to use Mailgun is the SMTP configuration similar to in Sendinblue?
In Sendinblue had to register, confirm. Go to Transactional emails, you see SMTP details like server, port, user and password. Used that information in Discourse installation and everything worked fine.

Or there’s additional configuration within Mailgun? Like configuring DNS/MX records?
Thanks.

This #howto gives a general understanding of the MailGun setup process. While it may not be the same for using Digital Ocean as a DNS provider, the general steps are very similar.

in containers/app.yml you can change these settings. Then ./launcher rebuild app
