Suddenly Cant Send Emails


I really enjoy em client and it has worked really well up until today. All of a sudden I get an error every time I try and send an email. Outgoing works well. It gives me an error message stating that “SMTP server doesn’t support authentication.”

I have turned on the logs for the SMTP and have them available?

Thanks for your help,



have you changed any settings recently? Anyway, please open the account settings and untick the option “Server requires authentication” under the tab SMTP.
