Yes, my experiments confirm it: add_header option in ACLs produces a single-line header, and attempt to split it artificially by "\n" results in stripping the tail of line (after "\n") into X-ACL-Warn: header.
That was asking to add two headers, the second with a default header name. Not one multiline header. The docs say: Leading and trailing newlines are removed from the data for the add_header modifier; if it then contains one or more newlines that are not followed by a space or a tab, it is assumed to contain multiple header lines. Each one is checked for valid syntax; X-ACL-Warn: is added to the front of any line that is not a valid header line. Try it with a newline, whitespace (i.e. tab or space) sequence, to get a multiline header. -- Cheers, Jeremy -- ## List details at https://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/
