how to process an email based on domain name

Hi

I am looking for a way to do the following.

Pseudo code:

if domain name of the sender is domain.com then process it through the
following block of lines and exit

|822field x-spam-status | egrep -iw yes >/dev/null && exit 100 || exit 0
|822field from | egrep -i "MAILER-DAEMON|POSTMASTER|ABUSE" >/dev/null &&
exit 100 || exit 0
|822field to | egrep -i "MAILER-DAEMON|POSTMASTER|ABUSE" >/dev/null &&
exit 100 || exit 0
|822field cc | egrep -i "MAILER-DAEMON|POSTMASTER|ABUSE" >/dev/null &&
exit 100 || exit 0
|822field return-path | egrep -i "MAILER-DAEMON|POSTMASTER|ABUSE"
>/dev/null && exit 100 || exit 0
|/opt/rt3/bin/rt-mailgate --queue help --action correspond --url
https://help.domain.net 2>/dev/null || exit 111

otherwise reply to the sender with the following autoresponder

|/var/qmail/local/bin/autorespond 600 10 autoresponder/sorry
autoresponder/log

So we are going to accept RT ticket request *only* from `domain.com'. Any
request
that comes from any other domains will get a auto respond to send their
request to some other address

write a script which does that, and make the appropriate .qmail-* file
point to that script.

i'm sure any number of people, myself included, would be able to write
you a simple script like this, in exchange for an appropriate fee.

otherwise, the information you need in order to build such a script
can be found in qmail's documentation, along with any beginner-level
book on shell or perl scripting.

Why? You already received the correct answer. If you think it won't work,
you need to explain why. Otherwise you're just wasting everyone's time here.

So I wrote this

if [[ $(< /etc/domainlist) = *${SENDER##*@}* ]]
then
exit 0
else
qmail-autoresponder -c -n 2 -t 60 /var/qmail/alias/AUTORESPONDS.DNS
exit 99
fi

It basically receives and checks domain name of the sender. If it
matches to the list
/etc/domainlist then exit with with 0 or it notifies the customer
with necessary instructions
of any changes and then exit out with 99.

Now it works just fine. However, it won't scale well if the domainlist
grows to say few thousands.

Looking for suggestion in how to convert it to CDB and then lookup
against that OR some rblsmtpd
trick.

Thanks

That's easy. Use cdbmake. (http://cr.yp.to/cdb/cdbmake.html). You'd
create a data file like so:

+11,1:example.com->1
+13,1:elsewhere.com->1

Then build it into a cdb:

cdbmake domainlist.cdb domainlist.cdb.tmp < datafile

Then you check the database with cdbget
(http://cr.yp.to/cdb/cdbget.html), like so:

cdbget suspiciousdomain.com < domainlist.cdb
