Configuration of exchange 2019 hybrid with other spam server.
Hi,
Anyone who knows which items do I consider if I make exchange 2019 hybrid server with other spam server as wblock.
As is environment
Server : Exchange Server 2019
All mailbox users : about 800 (On-Premise)
Spam server : wblock
MX record : wblock
To be environment
Server : Exchange Server 2019 hybrid configuration.
Mailboxes : On-Premise Exchange Server(500 users) , M365 Exchange Online (300 users)
MX record : wblock
Mail routing : mail centralized
Customer want to use their own wblock spam server with exchange 2019 hybrid server to secure their onprem user mailboxes. I am not sure is it ok to communicate with between exchange 2019 hybrid and M365 Exchange online using MRSProxy protocol when we do mail migration to EXO on blocking wblock.
Do I request to open in/out bound port as 80, 443 going through wblock without blocking mail migration? Please give tips to me. This is first time exchange hybrid migration with other spam server, I am confused of it.
Thx
hongwoo jin
