Secondary MX and soft reject

[FredMa01]

Hi,
With RSPAMD, when a message is tagged "soft reject", I noticed that it was bounced on my secondary MX.
How to avoid this?

Thanks
Fred

You have to provide details about reject messages and the way your secondary mx is set up. Ideally you would have rspamd on the backup too and sync settings so they would act the same.

I have RSPAMD installed on the 2 servers A and B:
Primary MX field points to A (priority 1)
Secondary MX field points to B (priority 10)
Sending an email to server A works well but as soon as a message is tagged "soft reject", it is sent to server B.
For example, here is the rejection message:
