Running an ASG220 Rev.4 appliance + Latest version of ASG
In my email reports I see some strange outbound (and inbound) traffic.
In my top-20 Sender report I have 4-5 email addresses sending out 20-30 emails per week.
These aren't my LAN users - feel like there could be malware running on host systems within my network.
Unfortunately, I can trace the source of the host that particular address is sending from (Astaro doesn't let me do this)
What are some thoughs about where/why/how and what are these "rogue" email senders???
Some network details: Running an http transparent proxy, up2dates are all up to date, intrusion protection, POP3 proxy is enabled, firewall catches a solid 3-6 malware/spyware programs every week.
Thanks in advance - very curious about this
