Message Repeatedly Failed to Upload

Switched to a new computer - was able to set up em client same as last time.

This morning I keep getting an error message that says “IMAP - Message repeatedly failed to upload, this might indicate server incompatibility”. Not sure why this happens - the message does get sent but I still keep getting these messages

I had a similar problem in version 7 - don’t know yet if 8 fixed it. Messages with attachments would be sent out over and over, and every send was fully completed, despite the error message. Difficult and embarrassing to explain to recipients.

I have had this problem for a few years, I was able to turn off the error notification in version 7, now in version 8 you get a warning icon (red triangle) in top menu bar, have not attempted to find a way to turn it off.
When I 1st started to get these error messages I contacted EM client, they couldn’t explain why I was getting the errors, then I sent my E-mail service (Netaddress) all my log-in info and a copy of the EM client error message, they said my login info is correct and they see no issues when they look at their server logs related to any of my log-ins.
Being a glutton for punishment I then went back to EM client with the response from Netaddress, their response was the same as their initial response, no one at EM client could tell me exactly why their software thought it was an error.
My guess is that EM clients error detection is wrong OR Netaddress was rejecting some attempts to use their servers to keep them from being overwhelmed, in ether case the responsible party (EM Client or Netaddress) will not admit to being the source of the problem.
If your successfully sending & receiving e-mail as I am, I say Ignore it!
