Reporting-MTA: dns; standard2.doveserver.com
Action: failed
Final-Recipient: rfc822;
[email protected]Status: 5.0.0
Why is this happening
looks like DNS lookups are failing from your SMTP server, its not a Roundcube issue.
Thanks.
Any idea what i should or can do.
Thanks
thats very difficult to answer. i dont know anything about your setup. as i said before the issue appears to be with your smpt server so look there, check the logs, test dns resolution etc.
