 * Hi,
    this might be a stupid question but I was wondering about security when 
   using an external email provider (in my case zoho-mail).
 * Here’s my postman config:
    **SMTPS to smtp.zoho.com:465 using Password (Plain)
   authentication**
 * I’m worried about “Password (Plain)”. Does this mean a 3rd party could intercept
   my login details as plain text? I know the connection uses SSL but I just want
   to make sure I’m on the safe side here.

 * SMTPS is protected at the network level by either SSL or TLS encryption. Your
   password is safe! Plain authentication means password authentication.

 * Thanks a lot Chief – one less thing to worry about 🙂
    Thanks to your plugin 
   my system mails don’t end up in my spam folder anymore.

 * To v1.6.13, I’ve added little emoji’s to indicate secure and insecure on the 
   Dashboard Widget and the Main Settings screen. Cheers! 🙂
