Not having used exchange, I was unaware of this. Does this only happen on a
local network, or do they connect using port 25 and then switch to X400 if
they realise they're talking to another exchange server?
Seems like an awful waste of time to me.

Let's see how many this effects.

In a survey of 20310 hosts in the *.net domain; 18441 connected
successfully. Of these, here is a summary of mailer usage.
Here are the server software tallies:
11583 sendmail
1102 Post.Office
778 IMail
638 MS Exchange
566 NT Mail
552 qmail
511 Netscape Messaging Server, formerly Netscape Mail Server
454 not sure
277 Eudora Internet Mail Server, formerly AIMS, formerly MailShare
211 Zmailer
[...and so on... ]
This gives MS Exchange about 3.5% of the market.
Best wishes
