I think this would help me and others who receive THOUSANDS of junk/spam/pornographic email each month reduce this problem immensely. In spite of all the other filters I've employed, I feel I must resort to this method. There's also no way to filter iPhone email - this would put you ahead of the curve. Thanks so much- Fri, 29 Aug 2008 22:50:47 +0000 https://bugs.horde.org/ticket/7263#t48590 This is not possible, because the filter frontend supports all kind of filter backends, and there is no means to get to Horde's address book from a server side filter engine like sieve or procmail. We could make this available for client side filtering only, but I'd imagine that's going to kill performance pretty quickly. Sat, 30 Aug 2008 08:20:54 +0000 https://bugs.horde.org/ticket/7263#t48607
