A few days ago I started noticing notifications from my email clients that there was an authentication error for my email address ending in @me.com. I tried re-entering my password several times, I changed my password, tried the @icloud.com version of the email address but unfortunately, nothing worked. I can however, still sign in to webmail at iCloud.com, and to other Apple services using these credentials, just not email.
Does anyone know what can cause this? I have quite a few internet accounts that depend on this email address.
Kind regards,

You are probably hit by the 'App Specific Password' feature. Apple recently changed their policy for 'third-party' Apps and Clients to require a password differing from your main AppleID password.
The following Apple Support link: Using App-specific passwords is a good place to start.
