I am having no luck with Weathercat sending outgoing emails. Using latest release of the software, on OS 10.12.2 on amid-2011 iMac. In Weathercat preferences, port 587 is designated. "Test Now" in that panel results in authentication failures. My email client is iCloud. Are those the credentials that should be in the "User" and "Password" fields in Weathercat? They worked in the past. Any help would be appreciated. Otherwise, all appears to be working well.
