How to use mailtrap.io with Liferay DXP

When setting up Liferay DXP it's necessary to add an smtp-server e.g. for resetting your password. For testing/development purpose it's easier to use a service like mailtrap.io. Simply add the portal-ext.properties with the right settings and you are good to go without spamming your users.

This is my portal-ext configuration to avoid static resources being cached after a new deployment in Liferay DXP. Mainly used for development purpose.

com.liferay.portal.servlet.filters.cache.CacheFilter=false
com.liferay.portal.servlet.filters.etag.ETagFilter=false
com.liferay.portal.servlet.filters.header.HeaderFilter=false
com.liferay.portal.servlet.filters.themepreview.ThemePreviewFilter=true
theme.css.fast.load=false
layout.template.cache.enabled=false
browser.launcher.url=
