Have found workable solution... use a better mail server (corporate relay instead of local exchange server) and write the registry keys for BLAT using kixtart instead of letting BLAT do it. Works MUCH better but still get the occasional error due to "file not found" when BLAT is told to email the contents of a text file. This works on 99% of machines, but the odd one or do it doesn't - any ideas what I should look for? Machines are all Winnt4.

Cheers!
