"solve" means some solutions like "only add a header if no previous one existes", which might work by either wrapping the add-statement in an condition or (since I add several other spam-related headers anyway) modifying one of the existing add-statement to use string-expansion to create one or more header-lines, which would be an alternative solution of preventing multiple headers.
The reason I mentioned the issue on this list: I don't consider the documentation to be absolutely specific and the way I understood it my question wasn't answered by the documentation. So I hoped for clarification here regarding the actual and the intended behaviour. Testing might have resulted in "it adds a second header", but then I would have asked "did I miss something that might enable exim to suppress the "add_header" if a header with the same name an the same value already exists". -- 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/
