I just don't like that idea and I'll try to use conditions to prevent that. Would have been nice if add_header had a flag to say "only if not already present", but such a flag would in effect only be a shortcut to a condition.

Even if it is discouraged I don't really like the thought to use the header for originally unintended side-effects. > 1. make the assumption that no end client really uses a value of > Precedence: that is other than bulk|junk|list, especially if the message > is likely to be spam > > 2. rename any existing Precedence: header to be X-Precedence: or > something, so at least its original value is preserved somewhere if the > user really wants to see it I'll try something like "if a Precedence: header exists: dont't touch it, otherwise...", but that would make it impossible to realise wheter the header has already been present or just added by me.... > 3. then let Exim add "Precedence: bulk" to allow Exchange to detect it. > > However, I see from: > > http://msexchangeteam.com/archive/2006/10/06/429115.aspx > > that Exchange 2007 will also not reply to a message with a header > "X-Auto-Response-Suppress: OOF", so this may be a solution more palatable > to the original poster. Shame - it would have been a good opportunity for That's a great information, but a migration to Exchange 2007 is only planned and so far I have to stick with Exchange 2003. Of course I'll start adding that new header anyway. At least by extending it with imftune and abusing that precedence-header, I'll be able to create a solution that's almost as nice as my usual unix-setup... ;-) -- CU, Patrick. -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
