We have some emails that don't go through. Checking the logs shows this:

2024-02-18 00:53:28	INFO	postfix/cleanup [3812112]	24DC417AA8A: milter-reject: END-OF-MESSAGE from lon103.XXXXXXX[XXXXXXX]: 5.7.23 SPF validation failed.; from=<XXXXXXXX> to=<XXXXXXXXs> proto=ESMTP helo=<lon103.XXXXXX>

Thank you for your post. As I can see you already present the reason why your mails are rejected. Are there any additional questions?

I need help to find out how to solve this problem

Have you set an SPF record for the sender domain and does it allow your host to send emails for the sender domain?
The error message also mentions that several records exist for the same domain name. This can be valid for some cases, but maybe the existing records are contradictory?

The error bellow means that the domain of the sender has Multiple SPF or TXT records configured. Which, as @Peter Debik pointed out already, can cause delivery issues.

24DC417AA8A: Error code: (32) Multiple SPF or TXT records for domain.

The error bellow means that SPF validation of the sender failed. Which causes the email message to be rejected by the server.

24DC417AA8A: milter-reject: END-OF-MESSAGE from lon103.XXXXXXX[XXXXXXX]: 5.7.23 SPF validation failed.; from=<XXXXXXXX> to=<XXXXXXXXs> proto=ESMTP helo=<lon103.XXXXXX>

The solution for both problems is with the owner of the sending domain. He/she needs to adjust the SPF record and remove any duplicate SPF records of the domain.

Okay, I realise the problem isn't on my end. Thanks
