Issue Forwarded mail is deferred in mail queue

frdho

New Pleskian
Hello,

I'm having some problems with accounts where e-mail is auto-forwarded. Mails for the account shown below are automatically forwarded to a @outlook.com account. There is no issue when e-mail is sent manually from this domain.

In the mail queue the @outlook.com address shows up as a recipient (filtering on mail queue in plesk doesn't work for me so I've copied it to an Excel to do this).

The errors I'm getting are all about the same: complaints that there are no valid SPF/DKIM/DNS records for the domain of the original incoming e-mail.

If we take a look at the last message, it was sent to the @kadrage.be address (hosted on my server) and forwarded to the @outlook.com address, but somehow, Plesk thinks that it needs valid records for @ansterken.com domain.

The e-mail forward is coming from my domain, so why is it checking records for the annsterken.com domain?

Further info: I'm using relay to send e-mail through my VPS provider. Plesk settings:

EDIT: my VPS provider says I should enable SRS (Sender Rewriting Scheme), but all I can find on this topic is that it is enabled by default on Plesk
