关于Lotus Notes服务器端邮件解密及加密关闭的技术问询

Great question—let’s break this down based on my hands-on experience with Domino environments. Your observation about the $EncryptionStatus field being 0 is spot-on: that confirms the encryption isn’t triggered at the application/form level, so it’s definitely being enforced by the Domino server or related configuration.

First, let’s pinpoint where the server-side encryption is coming from #

There are a few common Domino settings that force encryption for outgoing mail:

• Server Configuration Document: Check the Domino Directory’s server document under the Mail tab. Look for settings like Encrypt outgoing mail or rules that apply encryption to specific domains, recipients, or databases. Some environments enforce encryption for all mail leaving the Domino domain, which would affect your database’s outgoing messages.
• Database Properties: Open the LN database that sends the action items, go to File > Database > Properties > Advanced. Look for an option like Encrypt documents when sending—if this is enabled, it tells the server to encrypt any mail sent from that database, regardless of the form’s $EncryptionStatus.
• Inter-Domain Routing Rules: If the mail is being routed outside your Domino domain, check the Connection documents for encryption requirements between domains. Sometimes cross-domain routes are configured to encrypt all traffic.

Can you decrypt this at the server level, or modify the settings? #

You absolutely can adjust the settings to prevent encryption for these specific messages (decrypting after the fact is risky and not recommended unless you have explicit key access, which most admins avoid). Here are your actionable options:

• Exclude the target database from server encryption rules: Work with your Domino admin to update the server document or database properties to disable encryption for the specific database sending these action items. This ensures all mail from that DB goes out unencrypted, which works for users on non-Notes clients.
• Create recipient-specific exceptions: If you only need to unencrypt mail for that one important Outlook/Apple Mail user, set up a Mail Conversion Rule on the Domino server. These rules can detect the recipient’s address and strip encryption before sending the message as plain MIME.
• Adjust Internet Mail Format settings: In the server document’s Internet Protocols > Mail tab, ensure that Convert Notes rich text to MIME for Internet mail is enabled, and that encryption isn’t forced for MIME messages sent to non-Notes recipients.

A quick test to confirm #

Ask your Domino admin to temporarily disable encryption for the target database, send a test message to the Outlook/Apple Mail user, and verify they receive the full content instead of the "special objects" warning. This will confirm the server setting is the root cause.
