"tough" isn't always an acceptable answer in the Real World (ironic
considering your own email domain!). Nevertheless, I more or less agree.
My management may not, if the issue raises its head high enough up the
(monkey) tree, but that's how it stands right now.

Between these messages, I was contacted by a company with exactly this
problem. Their MTA returned only the first line of my multi-line error
message. Here is the banner from the MTA:
220 somesite.co.uk Microsoft ESMTP MAIL Service, Version: 6.0.3790.0
ready at Wed, 21 Apr 2004 16:32:03 +0100
Try not to look too astonished -- this is an Exchange 2003 server. While
I agree with other comments made recently that the latest version is much
better than previous ones, with regard to ability to turn on SMTP RCPT
rejections etc, it appears it still has problems.
