I recently became aware that my CF9 is no longer sending email to E2K7. My exchange SSL cert expired and I didn't catch it for 2 days. I renewed it and got it installed last night, so I thought email would start working again. It has not, which makes me think it wasn't the cert expiring. Here is what is happening/not happening:
I send an email using CF
CF mailsent log shows email sent successfully
Exchange message tracking log does not show any email activity
In CF admin, I verify mail server connection, comes back successful.
Sending & receiving in OWA works perfectly
I'm not sure what else to check. Things have always worked fine. CF reports sending the mail, but it never really makes it, as the Exchange server never shows any activity from the CF sent mail.
Can someone help me figure out what to check next? Could a recent windows update have broken something? Some new CF update I need perhaps? I'm at a loss.
