# Federation
# Note: Changing LOCAL_DOMAIN at a later time will cause unwanted side effects, including breaking all existing federation.
# LOCAL_DOMAIN should *NOT* contain the protocol part of the domain e.g https://example.com.
LOCAL_DOMAIN=example.com 

# Changing LOCAL_HTTPS in production is no longer supported. (Mastodon will always serve https:// links)

# Use this only if you need to run mastodon on a different domain than the one used for federation.
# You can read more about this option on https://github.com/tootsuite/documentation/blob/master/Running-Mastodon/Serving_a_different_domain.md
# DO *NOT* USE THIS UNLESS YOU KNOW *EXACTLY* WHAT YOU ARE DOING.
# WEB_DOMAIN=mastodon.example.com

# Use this if you want to have several aliases handler@example1.com
# handler@example2.com etc. for the same user. LOCAL_DOMAIN should not
# be added. Comma separated values
