Yes, if you can set it up so that your list command addresses pass
through EIMS instead of going directly to LetterRip.  You'll need to set
up addresses in EIMS for all of the accounts in LRP that should be
receiving mail - you know, listname-on, listname-off, your commands
address, all of that.

Assuming for example's sake that your lists are running from
"lists.nothingness.org", you'd follow the instructions available on the
Interwebs to change LetterRip to listen on a different SMTP port than
25, such as (for example) 26.  You'd then set up EIMS to receive mail
for "lists.nothingness.org" and add a mail route so that mail for
"lists.nothingness.org" got routed to "lists.nothingness.org:26".  Add a
separate firewall rule somewhere (if you like) to make sure that nothing
but EIMS can reach LRP on port 26, and bingo - all of LRP's incoming
E-mail is now being filtered through EIMS.

This page and similar ones have more details:

.html>.  Google is your friend here, as is the LRP manual.

Theoretically, to get up and running faster, you could set EIMS to allow
mail to unknown accounts and forward it *all* to LRP, but you'll get
real SMTP errors if you set up real EIMS accounts/aliases for each
address that should be allowed to receive mail and let EIMS give the
SMTP "unknown user" error for everything else.

But before EIMS routes the message to LRP on port 26, it has to get
through graylisting, any STF or CounterAgent spam filtering, and so on. 
If you can block it using EIMS, you can keep it from getting to LRP this
way, and that may be your best immediate way of getting control over
LRP's inbox.  If a spammer gets through, though, LRP will still echo the
original message in its response, so it's no panacea - just triage.
