Not Receiving E-Mails since Sunday Night

Not Receiving E-Mails since Sunday Night

My Zoho account is in Morelia, Mexico.  There have been server issues once or twice before, but never for this long (have not received any e-mails since Sunday evening)!  I can send outgoing e-mails but when I send test samples from
another e-mail address, all I get is 'Fatal Error.. Daemon etc..'  My Zoho e-mail is sandy@sandydandrade.com but since that does not work (as noted0, my backup address is arborknits@aol.com.  Need help!   Thanks
