Topic: No DKIM signature

======== Required information ====
- iRedMail version (check /etc/iredmail-release):  0.9.6
- Linux/BSD distribution name and version:  FreeBSD 11
- Store mail accounts in which backend (LDAP/MySQL/PGSQL):  MYSQL
- Web server (Apache or Nginx): nginx
- Manage mail accounts with iRedAdmin-Pro? No
- Related log if you're reporting an issue: /var/log/maillog
====

When I send emails trough  SOGo our emails are DKIM signed but NOT when using Thunderbird as an email client, using same login/pass/recipient

These are our amavisd logs for both escenarios:

Trough SOGO gets DKIM signed

Well....thanks, but is certainly not my issue here. Like I said, my email are coming out signed when I use SOGO but not with email clients.

Re: No DKIM signature

Try to add "enable_dkim_signing => 1," in "$policy_bank{'ORIGINATING'} = {}" block like below:

$policy_bank{'ORIGINATING'} = {
    enable_dkim_signing => 1,
    ...
};

Restart Amavisd service and try again.

Hi, bartoruiz, hi, Zhang.
Yes! Same logs, same problem. I dig this for two weeks, but have still no result.
When the mail is LOCAL (i.e. from @mynetworks), then it signs. Otherwise - not.
Something is wrong with assigning a value to this variable (originating flag)...
