I am able to send to any internal email address from any internal address. I am not able to send to or from an external address to an email address on zimbra. Anytime I try to send from hotmail or whatever, I get this error:
Diagnostic-Code: smtp;553 sorry, relaying denied from your location [188.8.131.52] (#5.7.1)
It's driving me crazy, I can't seem to find the right place to allow this to work. Any help for a noobie would be great! Thanks in advance!
