Hi Scott,

DKIM is deployed at the mail server and DNS levels and is transparent to clients. Laserfiche integrates with customers' existing mail servers via SMTP and IMAP, so the question itself is Not Applicable. Laserfiche does not itself include a mail server.

If this is for an RFx where you must provide a response, you can say "Laserfiche supports sending emails over SMTP through a customer's own DKIM-enabled mail servers/services and domains."

From: Dmarcian - What is DKIM?

DKIM gives emails a signature header that is added to the email and secured with encryption. This DKIM signature acts like a tamper-proof seal for email to verify that it has actually come from the domain it says it does and that it hasn’t been tampered with.

To use DKIM, email servers are configured to attach special signatures to the emails they send. These signatures travel with the emails and are verified along the way by the email servers that move the emails toward their final destination.

Examples for common mail services:

Office 365 -  Use DKIM to validate outbound email sent from your custom domain

Google Workspace (Gmail) - Enhance security for outgoing email (DKIM)
