I've a question about this kind of configuration. I've configured ispconfig as mailfilter for a domain, so i've configured Email Routing and Relay Recipients. All works well as expectd. Now i would like to configure the dkim for that domain, but i've to enble the domain to generate and configure DKIM, but as expect, all mail in this case are threated as local delivery, and obviously i'll get the error Code: Recipient address rejected: User unknown in virtual mailbox table I've tried to change something to get that configuration work, but no lucky. Any idea about that?
As far as I know, you can not use DKIM in ISPConfig for mail routing setups at the moment. But probably Florian can answer that as he developed the DKIM implementation for ISPConfig.
If you really want to change routed mails (i think, the original-mailserver should sign the mails), you can try to add the domains to amavis @local_domains_acl, store the dkim-private-key in /var/lib/amavis/dkim and add the signing to /etc/amavis/conf.d/60-dkim.
