## Remote media attachment cache cleanup
Mastodon downloads media attachments from other instances and caches it locally for viewing. This cache can grow quite large if
not cleaned up periodically and can cause issues such as low disk space or a bloated S3 bucket.
The recommended method to clean up the remote media cache is a cron job that runs daily like so (put this in the mastodon system user's crontab with `crontab -e`.)
```sh
RAILS_ENV=production
@daily cd /home/mastodon/live && /home/mastodon/.rbenv/shims/bundle exec rake mastodon:media:remove_remote
```
That rake task removes cached remote media attachments that are older than NUM_DAYS, NUM_DAYS defaults to 7 days (1 week) if not specified. NUM_DAYS is another environment variable so you can specify it like so:
```sh
RAILS_ENV=production
NUM_DAYS=14
@daily cd /home/mastodon/live && /home/mastodon/.rbenv/shims/bundle exec rake mastodon:media:remove_remote
```
## Email Service
If you plan on receiving email notifications or running more than just a single-user instance, you likely will want to get set up with an email provider.
