I can no longer send emails from one of my accounts. They are just sitting in my outbox. I have not changed any settings so I’ve no idea why this has suddenly started. I can receive ok using this account and send (and receive) using my other account.
I read in this forum about other people who had the same problem and tried the Tools/diagnose solution but it couldn’t fix it.
I have updated to the latest em Client and have re-booted my computer but still no success.
