Exchange 2019 on premise server configured two Send Connectors. (Single Server in the domain with Mailbox and transport roles)
1 connector directly to the internet via domain mx records
2 connector to a smart SMTP host on same subnet
but I am not getting any email delivered neither to the destination nor to the local smart host ( i only keep one connector enabled at the time )
Exchange server windows firewall is disabled . I am receiving emails emails from outside to the server. I can telnet on port 25 to another SMTP sever local and on the internet
but don't have email flow from Exchange 2019 to outside or to smart host?
how can i troubleshoot it?
I would appreciate an answer from a real experts and not just simple googled links.
