The address "[hidden email]" has been added to LocalAddresses_Flat list.
I have two kinds of users. Real local users who use my system to both
store and retrieve their mail and users who only use my system as a
forwarding, spamfiltering service, and it's only the second group who
gives the errormessage.
How do I configure it to allow the sending of whitelist receipts to
"external" addresses? (external meaning an account not on my system but an
address in my LocalAddresses_Flat list)
