Can I configure something like SPF exception for particular incoming SMTP domains? I mean- if I receive emails from partner's domains with not properly configured or without SPF records I don't want to have this emails in junk or quarantine. I think allow list is not good solution because I also don't know to bypass this emails without any kind of scanning. Can I achieve this functionality in EOP? I have this option in Forti Mail for example...

    in EOP, you should use the Tenant Allow/Block List and only use that if you can:

    At some point, you HAVE to use a allow mechanism if you want to ensure these messages get through.

    You can create the allow via submission:

    They will still be scanned for malware and the Tenant Allow list will teach Exchange Online rather than a transport rule that just allows the messages.

    Otherwise, a transport rule
