Can not send e-mails usubg EM Client

Mail
#1

I am using EM Client version 9.2.1222 (ca10485) and it stopped sending e-mails a couple of days ago. I am receiving them normally. This is the smtp log I got today.

SMTP S: 220 2.0.0 Ready to start TLS
23:22:57.670|059| Exception: MailClient.Accounts.ConnectionException: Conexão falhou devido a seguinte razão:
23:22:57.670|059| “Authentication failed because the remote party sent a TLS alert: ‘HandshakeFailure’.”
23:22:57.670|059| —> System.Security.Authentication.AuthenticationException: Authentication failed because the remote party sent a TLS alert: ‘HandshakeFailure’.
23:22:57.670|059| —> System.ComponentModel.Win32Exception (0x80090326): Mensagem recebida inesperada ou formatada incorretamente.

Did not make any modification i my PC during the last weeks.

You can try out one of the following

  1. temporarily disable the anti-virus/firewall and see if the messages can be sent
  2. check the setting. Go to Menu > Tools > Accounts and then look at the SMTP tab. The port should be 587 and the security policy Force usage of SSL/TLS.
  3. Go to service provider web page–support and insure you have the proper settings.

If none of the above works, I think you can also with to some other reliable and more efficient option for emailing like Outlook. All you need to do is configure your account to an outlook profile and start sending / receive emails.
