Not been using Antergos and KDE long as I moved over from Fedora a few weeks ago. I have just updated from KDE 17.08 to 17.12 and now KMail won’t send emails. I have a Googlemail account and one for my business, and both fail.
As my server is self hosted I checked my logs and it show KMail connecting and then a lost connection meassage after STARTTLS.
My laptop, which thankfully I haven’t updated and is still on 17.08 still works fine.
Does anyone have any ideas?
