I want Zimbra to forward requests, sent to firstname.lastname@example.org, to RT for processing.
Using the instructions here:
I was able to get things working internally. I can send mail from a local zimbra account to the support address and create a new RT ticket, or modify an existing one. BUT.... when I try to send mail from offsite:
sts23:~# telnet 126.96.36.199 25
