I have identified a large amount of e-mails stuck in the temptables of a exchange 2003 install. I know that the normal practice is to apply the correct hotfix, delete the temptables, restart and have the exchange subsystem recreate the temptables. However there are heaps of required e-mails that need to go to the intended persons.
Other than exporting the messages out of the temptables and then manually sending them off, is there anyway to "re-send" them from the temptables?
I had an issue with the slightly infamous "blackhole" Exchange 2003 bug that would blackhole emails that failed a graylist filter (or if anti-virus fudged with Exchange) in the temp tables.
I was able to resend them by restarting the SMTP service; not sure if that'll work for you, but an easy thing to try if you haven't already done so.
EDIT
I lied; I dig some Googling around and I'm pretty sure I put the following in a batch file and ran it as a scheduled task nightly (until we switched smarthosts upstream and didn't have this issue again):
