The postfix package has in the PERMIT_*_CDROM description "cannot be sold, see section 4 of license"
Is that the "4. COMMERCIAL DISTRIBUTION" in "IBM Public License" http://www.opensource.org/licenses/ibmpl.php ?
That section has a lot of crap about indemnification but I can't figure out anyplace where it says you can't sell it.
Do you really want to be in the situation where you have to indemnify someone who has the desire and the resources to sue IBM?
