Guys I need your help with this one - Every now and then I cannot send a mail (the bigger the more likely) - it stays in the outbound queue forever but actally gets delivered. I sent an offer to a customer which was delivered more than 40 times - no a good publicity is it :) I tracked it down to an exchange error saying that the network connection was "bad" or interrupted or whatever. Now since my ISA here is running on a very lame server, I suspect that it might have something to do with the machine not being able to serve the load. I haven't had any other problems with data transfer though. Any, preferrably good, ideas? Thanks Mark
