ic, the SPF thing.
Apropos, check the list mail's headers - you'll find that apparently
our LiLux overloards (i.e. whoever configures the mailserver on
sendar) has already set SPF up: there are "Received-SPF" headers...

I'll have to read up (as time permits) on SPF details... or else maybe
someone who already did might do a presentation @ a LiLux meeting?

Apropos presentation, we already talked about antispam setups...
that would be interesting - if someone feels like it...

While I'm at it, does anyone have a good link on how to set up
postfix with SpamAssassin (and amavisd), with potentially different
rules for different domains? I've done some RTFM, but there's so
much of that... somehow I didn't yet hit upon what I'm looking for.
