That mail was rejected, so it is not possible to deliver. The sender needs to send it again (from a properly configured MTA),

Is it possible to quarantine these mails? If so, how to configure it?
Thx

Try to add that IP address to the SMTP whitelist.

I am running Postfix on an hosted VM as smart host and for mail buffering if my exchange is offline.
Some mails get rejected because of:

pmg postfix/smtpd[2687]: connect from mx.domain.tld[xx.xxx.xx.xxx]
pmg postfix/smtpd[2687]: NOQUEUE: reject: RCPT from mx.domain.tld[xx.xxx.xx.xxx]: 554 5.7.1 <user@domain.tld>: Recipient address rejected: Please see http_www_openspf_org/Why?s=mfrom;id=no-reply%40post.at;ip=84.201.40.191;r=pmg.domain.tld; from=<no-reply@post.at> to=<user@domain.tld> proto=ESMTP helo=<mx.domain.tld>
pmg postfix/smtpd[2687]: disconnect from mx.domain.tld[xx.xxx.xx.xxx] ehlo=1 mail=1 rcpt=0/1 data=0/1 rset=1 quit=1 commands=4/6

If I add xx.xxx.xx.xxx to the SMTP whitelist there will be no spam detection anymore because all incoming mail go through xx.xxx.xx.xxx?

xx.xxx.xx.xxx to the SMTP whitelist there will be no spam detection anymore because all incoming mail go through xx.xxx.xx.xxx?

No, just add the address to the SMTP whitelist. Then SPAM detection is still done, but tests like SPF at the SMTP level are skipped.
