I've been using K-9 for years without a problem. I'm presently using it on a Samsung Galaxy S9+ and all was fine until today when all emails sent with wifi on failed to send (error message was failed to connect to SMTP). I can open web pages without a problem and if I turn wifi off I can send the emails over 4G. I have made no changes to any settings. I am running the most recent version of K-9. I have double checked my SMTP settings and they are correct.I can send emails from Samsung's email app or from the Gmail app over wifi without a problem.
Any idea how to fix this or do I need to switch to a different app to be able send email over wifi now? -- You received this message because you are subscribed to the Google Groups "K-9 Mail" group.
