Hi all, I've passed a couple of weeks trying to set up dkfilter to run on my servers without success, using http://jason.long.name/dkfilter/ and http://xavier.perseguers.ch/open-source/dkim-dkfilter/ to support multidomain signature, but failed to sign my outgoing emails , I know that Spamassassin can use DKIM to sign email but dont know if it is able to be managed via ispconfig and managing multiple domains with different keys any help would be great
dkim is not integrated in ISPConfig. If you want to try to enable it manually, use the spamassassin configuration in /home/admispconfig/ispconfig/tools/spamassassin/
I think that in this case, if an upgrade is made to ISPConfig, the configuration in spamassassin will be lost, am I right ?
That's right. Did you have a look at this tutorial? http://www.howtoforge.com/postfix_dkfilter_domain_keys_implementation
