I'd suggest setting up SPF and/or DomainKeys. This will prevent people
from forging mail from your domains, if the receiving server is also
running these. If the receiver is not, well, then you can point out that
it's their fault.

BTW, I am shortly going to be setting up a company producing spam-fighting
tools. Anyone who is interested, please contact me off-list.
