We changed SMTP servers recently. I've got an SSIS package that sends mail.
It is set to find the SMTP server using the DNS name of the server, which is appropriately pointing to the new server. However, when the package executes, it sends mail through the old server.
I've set the SQL server to restart in the morning before everyone gets in. I expect that to force the server to re-load the DNS cache.
However, if I didn't want to restart the server, what would cause that service to re-query the DNS? Would just stopping and starting the SSIS service work, or is there another service that would need restarted?
