Hello iRedMail users!

I'm encountering issues where email sent as a result of a roundcube managesieve filter is not being DKIM signed.  For example, vacation notices, email notifications, etc. all go unsigned.

All other outgoing mail is correctly DKIM signed.

Is there a simple fix for this?

Re: DKIM on managesieve filtered messages

In your amavisd config file, make sure you have "d =>" for catch-all domain like below (replace "<my-domain>" by your real domain which already has DKIM key locally):

@dkim_signature_options_bysender_maps = ( {
    '.' => { d => "<my-domain>", a => 'rsa-sha256', c => 'relaxed/simple', ttl => 30*24*3600 },
} );


Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?

As discussed in https://bitbucket.org/zhb/iredmail/issu … e-not-dkim

1. Open /etc/postfix/master.cf, then look for the pickup transport configuration.
2. Add the following code below the pickup transport code

-o content_filter=smtp-amavis:[]:10026

This should look something like

pickup     unix  n       -       n       60      1       pickup
        -o content_filter=smtp-amavis:[]:10026

Then restart postfix.

This code was suggested by Zhang. All the thanks to this great man!
