I am trying to add SRS to a server to deal with mail forwarding, following these instructions <https://github.com/Exim/exim/wiki/SRS>.
I have the forwarding part working. The reverse part works as well, but I want to tweak it. If a hash has expired or someone is trying to hack it the router rejects the mail. When the router rejects the message, it returns an undelivered notice back to the sender. I could see this being used much like DNS amplification, someone could pound a victims email address using our server. I would prefer if the SRS hash is invalid and the router rejects, that it sends the message to :blackhole: Is there a way for me to specify in a router if it fails, direct the message to :blackhole: Rob -- ## 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/
