Hello everyone
i confused to integration with PMG and Exchnage 2019 , i just did setup both of them in same subnet and only internet access redirected to PMG for External communication, i have problem with receiving email from out side , in advance i did setup receive connector to fetch mail from PMG but its not working,

Outgoing : Users----->(25)Exchnage----->(25)PMG----->FW-----Internet
Incoming : Users<----Exchnage(25)<-----PMG(26)<-----FW(25)<---Internet

any help to fully explain this integration?
 
I think it is the other way around with the port numbers:

Outgoing : Users----->(143/993/110/995/587) Exchange----->(26) PMG----->(25) FW-----> Internet
Incoming : Users <----Exchange(25) <-----PMG(25) <-----FW(25) <---Internet

Have you swapped the ports as mentioned in 2.3.2?

with MS Exchange you should not use port 26 for outgoing so you have to
switch these two values (25 and 26) . In the end you have to
use port 25 for outgoing and port 26 for incoming mails.
 
Thank you eilko again , i found my fault !
i just miss configured receiver connector in Exchange server
