Domain Routing, with account exception?

Hello;

I have a server running "Sendmail version 8.13.8, config V10/Berkeley"
as a domain relay. It forwards all email to our internal Exchange
server. I'd like to be able to specify a specific account that gets
processed by Procmail instead of automatically relayed. Is this
possible?

My tests show that, currently, the mail messages are relayed without
any Procmail filtering at all and no attempt to match the messages to
a user account on the external server is attempted.

Does anyone know the best way to accomplish this? How do I get all
mail relayed except those messages addressed to one particular
recipient (I'd like those messages stored in a file, instead)?

Thanks!

I would say, you need to enable virtual users and add the specific
account there to map to local account, then setup that account to
filter the mails and remail them to final mail drop.

It might be possible to skip the local account and map the mail
address directly to a prog, e.g. "| /etc/mail/smrsh/procmail
arguments", but then it is running with the default uid/gid of
sendmail.

There had been posts regarding a "procmail" mailer, by introducing a
fake mail domain by Andrzej (Andrew) A. Filip, unless I'm mistaken.
Maybe, this works, too.

There had been some suggestions to "reroute" addresses from access DB:

sendmail.mc
LOCAL_RULE_0
R$+ < @ $+ > $* $: < $(access REROUTE:$1@$2 $: $) > <$1> <$2> <$3>
Check if to reroute address to different host; default to <>
R<$+> <$+> <$+> <$*> $#esmtp $@ $1 $: $2<@$3>$4 Reroute to different
host
R<> <$+> <$+> <$*> $: $1 <@$2> $3 Restore old line for system rules

(Tabs in front of $: and $# and the comments)

access
REROUTE:from@example.com to@example2.com

Maybe this works for $#*prog* mailer, too, or in combination with
Andrew's procmail mailer.

Sounds like an application for the "LDAP routing without LDAP" recipe
which has been discussed here in the past. Ie. use the ldap_routing
FEATURE with a hash map instead of an LDAP map, like so:

FEATURE(`ldap_routing', `hash /etc/mail/mailhosts', `hash /etc/mail/mailrouting', `bounce')

That way you can configure forwarding individually per address.
See http://www.sendmail.org/m4/ldap_routing.html for details.
