Hello Networkers:
We have a monitoring system that allow us to create a "robot" in order to excecute specific task. We have configure our robot to open a session into gmail and send e-mails to our mail servers. The robot will also send e-mails to gmail from our mail servers. The monitoring system is behind the inside interface of the firewall. In order to accomplish this task , I've been informed by the administrators of the monitoring system that we must open port 25 and imap from the monitoring server to gmail servers. I can't do this through the IP range of gmail because it changes frequently therefore this is not a feasible option (as far as I know). Is there some sort of URL filtering, inspection that I can apply for this in order to accomplish this goal ? what would be the best approach for this ?
Any recommendation will be greatly appreciated,
Regards,
