I am not sure when this started. It could have been after installing X3 v0.17.1 or X3 v0.17.0. It could have been after configuring CloudFlare.
I am getting the 'X' failed email send when attempting to send email from the contact menu option of www.merelyafleshwound.com
I don't think this is a CloudFlare thing as I don't use email from the merelyafleshwound.com domain.
Any help would be much appreciated.
