Hello everyone! I came here perhaps with a classic XY problem. We have an on-premise Exchange server with SPF and other NS records. My question is: if I set up a Chatmail relay on the same domain (not the same server) as the Exchange server and setting up necessary NS records for it, won’t that disrupt Exchange operational capabilities regarding sending and receiving emails? maybe somebody tried that already
Before you ask: I tried to connect Delta Chat client with the “use classic email server” option, but it apparently doesn’t work because Exchange uses its own MAPI protocol, and it didn’t work for me with IMAP for some reason.
