Our Systems Infrastructure team upgraded our mail servers this last weekend and now all our jobs that generated emails are no longer doing so. We updated all our mail server settings in our jobs several days before the upgrade and they were all still working fine. but after the physical upgrade they are not working. Has anyone seen this issue and have a possible resolution? I am sure it is a configuration issue on the exchange server, but I do not know where to look. Any assistance would be extremely helpful.
Need more details. What type of upgrade? In place or did they do a parallel upgrade and fail over to new servers? If new servers, I would check with my firewall folks. You stated you all made configuration changes to your jobs before the upgrade, what type of changes? Mail server IP or DNS, profile email address account, port, etc? Have you reviewed the mail log to see what error SQL is giving, timeout, invalid user, can not resolve host, etc?
