Exim signs the whole message. Partial signing is done by a length "l=" being specified in the DKIM header. So far as I know Exim does not support creating signatures with that feature. > It is required also that the recipient could handle the message (possibly > as an attachment) to a third party that could verify again the > authenticity of the message (same for the sender that would receive back a > copy to have a receipt that he really gave the messge to that server. > Is it possible ? (actually the verification is more impoortant for the > body and attachments than for the headers) Messages forwaded as attachments of type "Message/RFC822" can have their signatures verified. -- This email has not been checked by half-arsed antivirus software -- ## 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/
