Have used K9 for years and love it. Several email accounts working perfectly until recently.
Suddenly my emails to contacts with Gmail accounts are finding anything from me is sent to their spam box.
Initially I thought this was a problem with Easily, my main email account, but test test testing has proved that it’s anything sent from K9 on my tablet. Emails sent from the same accounts via my pc are getting through ok.
Any thoughts gratefully accepted.
