Error sending to gmail accounts

I get the following error message when sending to gmail accounts.

----- The following addresses had permanent fatal errors -----

OK. the first thing is that it is better if you do NOT show the full email address, fo instance **** would be better.

If the address you have shown is the only address that has a problem, it is what it says “a permanent error” you will need to contact the intended recipient some other way to confirm the address.
If not, who is your email provider?
The SMTP settings in eMC
What version of eMC?
Your OS system?


¡Buena suerte!
