I have one recalcitrant server that runs one old application, which sends important emails once in a while. Unfortunately, amavisd quarantines these emails for various reasons, mostly to do with bad headers. The sender is not unique and the admin has not been able to change that.
Of course, its IP address is in the middle of @mynetworks. How can I exclude that one host from header checks? Is there a way to _exclude_ this one IP from @mynetworks, then have a separate policy applicable only to this one IP? What am I missing?
