For some unknown reason, emails stopped being sent from about 3 different installs of drupal/ubercart. Above are the specs. They're all 2x, only one is updated to latest version, but none are sending emails. Any idea what might have caused this? I'm thinking something server-wise but thought I'd ask here as well, tap into some groupthink.
edit: looks like it's affecting Webform module as well. I'll have to ask this on the main drupal forums as well.
