We are continuing to have problems wherein my domain (RAPADOCS.COM) is bouncing messages from the HEALTHTEXAS.ORG domain. I can send email to that domain, however they cannot send to me. I'm not sure where the the problem appears to be and I've checked our SONIC firewall. Maybe I'm missing something and it's not allowing email from HEALTHTEXAS.ORG because my Sonic Firewall refuses connections from email servers whose inbound and outbound port addresses do not match. I'm not sure if this is the issue and I'm not sure how to troubleshoot this issue.
