Hey folks,
I recently set up an e-mail encryption gateway (Ciphermail Community Edition) on a separate machine. The virtual Servers are connected via VLAN and everything works as expected, except DKIM signing. The signature is attached but breaks after the mail has been encrypted.
It works as following:
- all sent mails are forwarded to the gateway
- processing takes place like encryption
- mail is reinjected on port 10026
- mail is delivered (dkim signature is invalid)
I need a way to postpone the dkim signature to basically the point after the mail has been reinjected for sending out.
It would help if I knew how to tell rspamd to sign mails only when they are delivered from the source of 10.1.0.30 (which is the gateway on the vlan).
Does anybody of the community know how to do that? Any help and pointers to where I could start are highly appreciated.
Thanks a lot in advance! š
