how to set spf record

Hi, I have an own postfix server and have set up DKIM/DMARC/SPF I thought correctly. However, whenever one of the e-mails sent from my box say user@mybox.net  to destination@otherbox.net. And this latter has a forward to destination@gmail.com then my e-mail fails spf and gets reported as SPAM. Is there anyway I can prevent this from happening?

Is this ipv4 only setup?

Re: how to set spf record

If I understand you correctly, I don't think so... I link this protonmail support page as a primer only as it has a pretty good high level break down of SPF/DKIM/DMARC requirements.

Quoted from link above:

However, keep in mind there are risks for choosing these actions. For instance, when you email a mailing list which then forwards to individual recipients, this will break SPF.

For that reason mailing lists like mailman have an option to replace the From-header or wrap the mail into a multipart message, for example: https://wiki.list.org/DEV/DMARC
