How do I stop this and get that "We do not relay" error that I've seen coming from other servers?

What version of sendmail are you running (i.e. what SuSE version)? Sendmail 8.9.x (as of SuSE 6.1) includes built-in Anti-Relaying support and this is enabled by default. I just hope that YaST doesn't disable it... I personally don't let YaST create my sendmail.cf but do that myself (using m4 macros - pretty easy actually). If you are interested I can send you my ".mc" (m4 input) file (used the /etc/mail/linux.mc that comes with SuSE as basis).

It's a sendmail thing, but it must be so standard that someone's going to know how to do it surely?

I just need my box to reject attempts to post through it (eg: other hosts trying to post mail to other hosts via my host) as a basic and I understand common anti-spam measure. Naturally, I still want this box to be able to receive mail being sent to local user accounts on it, and I want to be able to send mail from those local user accounts.

It depends which version of sendmail you're running. 8.9.x have relaying disabled by default, so if you're being allowed to relay through your box look for one or more FEATURE lines containing 'relay' in the sendmail.mc file, or hosts set as being allowed to relay in your access database. Earlier versions allowed relaying by default and had to be set up to prevent it through one of the anti-spam hacks. If you're running one of those versions it's really much easier to upgrade to 8.9.x than to fiddle with it. Drop me a line if you'd like to see a copy of my sendmail config. I generate my own through m4 BTW, having told YaST not to touch it.
