            You do not have permission to send to this recipient.  For assistance, contact your system administrator.
            <email.rolandfood.com #5.7.1 smtp;554 5.7.1  Sender address rejected: ACL mx_access.regexp - Your domain has an illegal MX record>

Tell me what Info you need. Or where can I look to best troubleshoot this.
Obviously one of my MX records is messed but but not sure why it's affecting email from 3 sites.

try this open Exchange System Manager, Servers, <your server>, Protocols, SMTP.
right click on the "Default SMTP Virtual Server" and choose Properties.
Click on the last tab delivery and then the button advanced.
In the box labelled "Fully Qualified Domain Name" enter the name that your server is known as on the Internet - mail.domain.com

25 procuda.rolandfood.com. [TTL=83000] IP=12.25.67.40 [TTL=83000] [US]
30 procuda. [TTL=83000] IP=[No Glue, No A record]

That last line is wrong and needs to be removed.
