DomainKey and DKIM working simultaneously in Kloxo

Updated 12 Oct 2026 · 64,754 views

I have DomainKey and DKIM working simultaneously.

Here's what you need to do

1. install Mail::DKIM perl module

yum install perl-Mail-DKIM

2. install libdomainkeys

wget http://mirrors.qmailtoaster.net/libdomainkeys-toaster-0.68-1.3.6.src.rpm
rpmbuild --rebuild  libdomainkeys-toaster-0.68-1.3.6.src.rpm
rpm -ivh /usr/src/redhat/RPMS/i386/libdomainkeys-toaster-0.68-1.3.6.i386.rpm

3. download http://www.memoryhole.net/qmail/dkimsign.pl and copy it to /usr/bin
4. download http://www.memoryhole.net/qmail/qmail-remote.sh
5.

mv /var/qmail/bin/qmail-remote /var/qmail/bin/qmail-remote.orig
cp qmail-remote.sh /var/qmail/bin/qmail-remote
chmod 755 /var/qmail/bin/qmail-remote
rm /var/qmail/bin/qmail-queue
mv /var/qmail/bin/qmail-queue.orig /var/qmail/bin/qmail-queue

6. edit /var/qmail/bin/qmail-remote. goto line 49 and replace

error=`(dkimsign.pl --type=dkim --selector=default \

with

error=`(dkimsign.pl --type=dkim --selector=dkim \

7. finally do not forget to add DKIM DNS TXT record.

dkim._domainkey.yourdomain.name.     IN  TXT  "v=DKIM1; g=*; k=rsa; p=MEwwDQYJKoZIhvcN.....AQAB"

the "p=MEwwDQYJKoZIhvcN.....AQAB" part is same as that for your domainkey created by kloxo

you can do a test by sending mail to yahoo or gmail

This basically works on most qmail toaster installation.
