Exchange 2003 mail getting lost???

I’ve had an ongoing scenario on my SBS 2003 server that I’ve never fully investigated in which mail to some yahoogroups gets “lost”. You check the SMTP queues and it’s not there so you believe it’s gone out. Then later when you reboot your server, it suddenly appears!!! apparently if you restart your Exchange Information Store or the SMTP service it will also reappear. Henry Craven discovered this little KB that was released last week which sounds just like the problem that I’ve been having – Thanks Henry – I’ll try it out and see how it goes!
