HostMonster Picky MX Records
If a district uses mail services provided by HostMonster and you're in the process of updating DNS records to redirect the domain to their new Streamline site.
Make sure that when you are adding these records [52.32.196.230, 52.70.155.240 and production.getstreamline.net.]
That you check the MX records there should be 2! If not then add the second MX record bellow and redirect it to the mail A record they have. In this case this is their A record: mail 67.20.76.229
1st: @ 0 monticellolibrary.org - Should be there already
2nd: @ 1 mail.monticellolibrary.org - This is the MX record to add if it's not there already!
