Mail: can't send email attachment when attachmentUrl has an embedded username & password

[watou (John C)]

Hello! This rings a bell:

@watou

… I recommend pulling the attachment to the openHAB server’s /tmp directory first in your script or rule (possibly exec’ing curl to do that), naming it as you want to see it attached, and then using a URL like file:///tmp/mylovelyimage.jpg to attach it to the email.
