Add a config option with all the other alerting options for HTML emails. I don't think the existing option worked, because $config['transports'][mail] = 1 instead of an array.
Auto-Deploy finished, Test PR at http://3221.ci.librenms.org or https://3221.ci.librenms.org
All good, tested with both html on and off and the correct content-type is set in the emails.
We need something adding to the docs so people know:
If you can add something in then we can merge.
Add web config option for HTML emails
@laf: Documented, rebased, using schema 108 instead of 107.
@f0o Any thoughts on this. I've tested both on and off and it sets the content-type correctly.
@Mattz0r: you will need to update your config now that this PR has been merged
