I'm having problems with an account since a few days and it's not being solved.

I have a zoho account that's working properly, I receive e-mails. But since a few days I can't receive these emails in my Gmail account who was connected by pop.zoho.com

This is the error message I got:

	El servidor negó el acceso POP3 al nombre de usuario y la contraseña proporcionados.
	El servidor devolvió el error "Authentication failed"

How can I fix it?

Thank you!!
