Hi!
One of my recipients reject my messages with this:

<ksn@mega-com.ru>: host mx0.gcom.ru[195.208.150.18] said: 550 5.7.0 DKIM key
    retrieval failed (in reply to end of DATA command)

I did not set up DKIM in my MTA, and use default settings for this. How I can fix it?

Re: DKIM service error

iRedMail has DKIM signing by default, you should add TXT type DNS record so that destination server can verify it. This is recommended way to solve this issue.

The **BAD** solution is, disable DKIM signing on your server.
