I send a url back in the rejection messages for instructions on how to
contact us so that legitimate mail can be whitelisted if they're showing
up in one of the blacklists.  In the last 6 months or so I've had to
companies that we do business with that use a hosted e-mail service get
blocked by sorbs.  And one that is on a DUL list as they send out from
their local mail server, instead of through any of their registered mail
servers.  If it wasn't for the RBLs our mail server would've succumbed
to the massive increase in spam several months ago.

I'd look into white listing Swedish mail servers.  Not being able to use
RBLs is extremely limiting.  Perhaps it's time to start lobbying your
government for changing their guidelines.
