Best regards

Could help me, every day my account is blocked because I send several emails to the same company domains, my email is ayuda@sescaribe.com, I am the secretary and I must send emails informally to my colleagues, I have been working very well since last year, but now mails are constantly bouncing

I appreciate your help

I receive this when we do not reach email recipients:
