Hi all, I recently set up Amazon SES as a Relayhost for some of my ISPConfig email domains but I have some questions: When DKIM signing is enabled in SES, do I need to disable DKIM for the email domain in ISPConfig or can I keep it enabled? If I can keep it enabled, did someone manage to set up "Bring Your Own DKIM" successfully using SES and ISPConfig? I pasted ISPConfig's generated DKIM private key into the SES web interface and needed to create a CNAME record for verification. However, that collides with ISPConfig's own DKIM signing then (as ISPConfig creates a TXT record for the same DKIM selector). When email forwarding is set up for a domain that uses SES as a Relayhost, some messages cannot be delivered: Code: <[email protected]> (expanded from <[email protected]>): host email-smtp.eu-central-1.amazonaws.com[184.108.40.206] said: 554 Transaction failed: Duplicate header 'DKIM-Signature'. (in reply to end of DATA command) Any help is appreciated.
