Ok. (going OT now)

[ computer(s) ] --- [ router ] ---> inet.

Router gets a dynamic ip adress. Mail is sent from my computer. So
how exactly do I tell sendmail to lookup my global adress and use
that instead of my hostname ? ...and get all the SMART_HOST etc.
rules to work still ? But see below.

I am incapable obviously. I assume anyone not grown up with sendmail
or the like won't be able to do so either. If you are able to do all
those tweaks for the usual setups, please submit a howto to the NetBSD
guide, or htdocs. Thank you in advance. I'm ok with it then, too :)

There's no need to answer as I'm looking forward to your howto :-)

PS: As long as the netbsd guide suggests you use sendmail in a way which
locks you out from netbsd mailing list if this is used as spam-protection,
could as well just shutdown the mls.
