Hello,

When using Roundcoube or any mailclient my emails are DKIM signature signed.

But when emails sending through MTA (e.g. the site's notifications) the DKIM signature is missing.

I use the default iRedMail settings.

DKIM record in DNS and 'amavisd-new showkeys' are correct too.

I have read this post https://forum.iredmail.org/post53218.html already.

In Google I found the settings for postfix and open-dkim only.

Is there anything else I should do to sending my emails with DKIM signature?

Thank you.

I send emails using the PHP script

Enabling SMTP authentication in your PHP script will fix this issue.

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