Hi Mates!
After users complaining about the emails from external domains marked as spam, i've check the zimbra logs to find problem.
I found this error in log file which tells the dkim is failed but why?
dkim: FAILED third-party signature by d=notification.microsoft.com, From: <emailassress@microsoft.com>, a=rsa-sha256, c=relaxed/relaxed, s=selector1, i=@notification.microsoft.com, fail (message has been altered)
dkim: FAILED Author+Sender+MailFrom signature by d=gmail.com, From: <emailaddress@gmail.com>, a=rsa-sha256, c=relaxed/relaxed, s=20230601, i=@gmail.com, fail (message has been altered)
does anybody knows why is it happening, i mean failing DKIM verification from all external domains?
