I don't believe so.

Exim cannot offer this service. All it has is the -R option, which
releases any message with a recipient whose address contains the given
string. This is not "any domain names that are formed with a suffix of
the specified node name". For example, if you run
exim -R root@
it will release all messages with recipients root@<something>. This just
doesn't relate to "nodes" (whatever they are) or domains.

If you run "exim -R foo.com" it would also release, for example,
messages addressed to x@??? or even "foo.com"@???.

Only some of the time, which is why I did not implement it originally. I
didn't want to run the risk of being accused of not following the RFC.

This is the nearest I could think of to what -R actually gives you.

It isn't really a separate queue, but I reckoned it could be thought of
as some kind of virtual queue, so that's what I implemented.
However, in the current version of Exim you can configure it to
recognize @ or anything you like by setting the etrn_command option.
So by that means I think everybody can be happy. Hopefully.
