others receive my me.com mail in spambox
How can I restore my mail settings (SPF record?) so my mails won't end up in the spambox of receivers? This occures now after using server LaPosta for newsletters with my me.com address as sender.
Could you elaborate?
Which version of macOS Server.app are you using, prior to 5.7.1?
SPF is set up in the public DNS of the domain to identify the authorized mail servers for that domain, and is not set in the mail client.
And unless you’re one of the rare folks providing authoritative DNS to the internet directly from your own DNS server, that all happens via your DNS provider. This if you’re running your own mail server, and which I have my doubts is what you’re doing here.
SPF is one aspect of spam filtering, and I’d expect receiving mail servers honoring SPF would just drop arriving bogus mail.
If the folks are receiving Apple me.com mail—and which obviously does not originate on your mail server—then you’re probably sending out what appears to be spam, and—as Apple doesn’t support other domains for me.com mail—you have no access to SPF settings for the me.com domain.
If you’ve been spoofing your me.com address while sending from other mail servers and other sources and as it might appear (and if you are not running macos with Server.app installed, and not otherwise running your own mail server), then that mail probably got detected as spam and got filtered and/or got your me.com sending address blocked.
In aggregate, you are apparently sending out messages that are being detected as spam. Each mail recipient gets to whitelist you.
There’s a whole pile of ”fun” with GDPR here too, if you’re at all dealing commercially with folks subject to that.
So.... what are you up to? And are you using your own server?
