Exim doesn't sign outgoing mails (Domain Keys)

[xy_bogdan]

Hello everyone,

I have recompiled Exim with Domain Keys support.

# strings /usr/sbin/exim | grep dk_selector
dk_selector
dk_selector
failed to expand dk_selector: %s

I have created public & private keys and changed my DNS records. DomainKey's Policy Record Tester reports that the record appears valid.

I have added the proper dk_selector, dk_private_key and dk_canon tags in exim.conf, but the e-mails I send don't have the DomainKeys-Signature header.

Am I missing something?
