We switched to Exchange 2013 recently but on our last exchange 2010 we were receiving inbound external emails on a port we though was unique – port 2525 (from our backupmx/antispam service)
Come to find out later - Exchange 2013 has two “Default” receive connectors.
1. Default SERVERNAME FrontEnd (frontend transport) port 25
2. Default SERVERNAME (hub transport) port 2525
Anyway I didn’t stop to think to change the receiving port from the old 2525 to 25 (at the backupmx/anti-spam service) and the inbound relay was sending new email to port 2525 and Exchange 2013 accepted 2 days of external email on port 2525 instead of 25. So the hubtransport (2525) accepted the mail but I have no idea what it did with it – it’s not in any of the mailboxes (50+ users)…
I end up having the inbound antispam service send email to exchange on port 25 (frontend transport connector) and I am getting all new emails delivered properly to their mailboxes now….
But I would like to recover whatever Exchange received on port 2525 (the other default receive connector – frontend) for the past 2 days.
Is it gone/trashed/lost on Exchange forever?
Can anyone help with this issue? Thank you
