I was always able to scan for SMTP traffic when troubleshooting a MFP scanning to email issue on my laptop when using a HUB or Port mirrored switch. I then got a new laptop and now I am unable to see SMTP traffic when trying to scan to email from an MFP. I can still see everything else, ICMP, SMB, TCP and all else. When I try to scan to an email I cant see any DNS, SMTP, TLS or anything. It's as if nothing happened at all but the scan successfully sends to an email so I know it passed through the network. Anyone have any idea why?
