Exim does not handle addresses in the form of `bang paths'. If it sees such an
address it treats it as an unqualified local part which it qualifies with the
local qualification domain (if the source of the message is local or if the
remote host is permitted to send unqualified addresses). Rewriting can
sometimes be used to handle simple bang paths with a fixed number of
components. For example, the rule
^([^!]+)!(.*)@your\.domain$ $2@$1
rewrites a two-component bang path `host.name!user' as the domain address
`user@host.name'. However, there is a security implication in doing this as a
normal rewriting rule for envelope addresses. It can provide a backdoor method
for using your system as a relay, since the incoming addresses appear to be
local. If the bang path addresses are received via SMTP, it is safer to use the
`S' flag to rewrite them as they are received, so that relay checking can be
done on the rewritten addresses.
