====== Qmail ======
  * [[ qmail debian install ]]

==== Setting up RBL for qmail ====
Add this code to qmail service startup file.
<code bash>
if [ -f /var/qmail/control/spamhaus ]; then
   rblsmtpd="/usr/local/bin/rblsmtpd -r sbl-xbl.spamhaus.org"
else
   rblsmtpd="/usr/local/bin/rblsmtpd -r cbl.abuseat.org -r dul.dnsbl.sorbs.net -r http.dnsbl.sorbs.net -r misc.dnsbl.sorbs.net -r smtp.dnsbl.s
orbs.net -r socks.dnsbl.sorbs.net \
      -r spam.dnsbl.sorbs.net -r web.dnsbl.sorbs.net -r zombie.dnsbl.sorbs.net"
fi
</code>

==== Block sender based .qmail (Bouncesaying) ====

Here is the quick work around to block sender / domain using .qmail for user OR domain.\\
  * To disable "ketan@xyz.com" on domain "pqr.com" add code to file '.qmail-default'  under domain directory
  * To disable "ketan@xyz.com" on "info@pqr.com" add code to file '.qmail-info' under domain directory.
 
== To block sender : ==


<code bash>

| if [ "${SENDER}" = "ketan@xyz.com" ]; then /var/qmail/bin/bouncesaying 'RESTRICTED: Domain policy disallows sending email to our domain.'; fi;

</code>


== To block Domain : ==

Blocking xyz.com to send email to ketan@pqr.com

<code bash>

| /var/qmail/bin/bouncesaying 'RESTRICTED: Domain policy disallows sending email to our domain.' sh -c 'echo $SENDER | grep -qi "@xyz.com$"'

</code>

== To forward if outgoing match ==
<code bash>
|if [ "$SENDER" = "support@test.k2patel.in" ]; then /var/qmail/bin/forward fire@power.com; fi
</code>

NOTE :
- This line must be appear first in file
- when you restrict for user you must add user Maildir line after this line.
e.g. "/usr/local/vpopmail/domains/9/W/pqr.com/info/Maildir/"
