Troubleshoot sending iCloud email

[LCMember1755]

I have just installed a PA 3020 and it's great. I'm still pretty new to the device though and need some help troubleshooting iCloud email. I can receive iCloud email on all devices. I can send iCloud email from a browser. But I can't send email from any mobile devices (iPad, iPhones). It just hangs on "sending...". This was all working last week when I had my Sonicwall in place. I see iCloud-mail outbound application traffic being allowed but I don't see any iCloud-mail (or even iCloud-base) traffic coming back. I'm basically just sitting on the monitor tab to see if I can see any drops but there has to be a better way to troubleshoot. Can someone point me in the right direction?

Thanks,

Hello Mike,

Could you please verify the session from CLI 

>show session all filter source <your laptop IP> >>>>> see any session available on this PAN firewall for icloud.

If yes, then apply a command > show session id XXXX for details information i.e source interface, destination interface, rule, c-s and s-c packet count etc.

Thanks
