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. IMHO, processing of add_header have better to be improved, to produce lines up to 78 characters, as recommended by RFC. -- Eugene Berdnikov -- ## 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/
