Send me an email: [email protected]

I'll see if I notice any configuration issues and report back to this thread.

Weird, for my server spam assassin tells me my dkim signature is invalid but the dkim check in the next category says that it's valid.

Copying my reply to HN:

Some feedback: you should add a PTR record (reverse DNS) for studer.dev and mail.studer.dev.

I also noted that your DMARC record has p=quarantine, which depending on the details of your outgoing setup, may cause your emails to be placed in the spam folder if DMARC fails for any reason. I generally advise against using DMARC with any policy other than `v=DMARC1; p=none` or else you're liable to run into issues, it's not a very good standard.

Otherwise, your configuration looks good to me. Also try https://www.mail-tester.com to see what they think.

In case anyone is curious: I checked and the PTR record for my mail server (168.62.161.121 -> mail.studer.dev) is valid. mail-tester.com also gives me a 9.9/10, but I just tried sending an email to a Gmail account and it went straight to spam :(

I suspect it's probably a volume thing? As in I'm not sending enough email for Gmail to make any judgements about my mail server, since I'm only an individual. Of course there's not really a great way to resolve that...

For gmail, try adding an IPv6 address with proper reverse resolving. Tip from HN some time ago.
