Trying to setup DKIM for my domain but hitting issue. DNS is via Cloudflare.

Following the info here - https://www.hmailserver.com/forum/viewtopic.php?t=29402

But Im getting an error 1004 from Cloudflare when trying to save the TXT record

Lets say this is what Im entering...

Type : TXT Record

Name : dkim._domainkey.xpd.co.nz

v=DKIM1; t=s; k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC8nxXPJLVrZycHRDJgL1l/Euut3yPAGHS8CIqMUrwn7PmNoNUEYsoMkiBfRTXLTCpzU2+BceZ9CFyR9N3mJhndvgg6e6JBuVBYyqofAmfDqbuHz7FqF3H6bTdR5l9/5AQM3XFJeerzOO8cPY3VwYnhfUFswCU/suTcTK0+uMV1ewIDAQAB

Gives me a 1004 error - Validation error.

If I remove the key, it saves fine.

What am I missing ??

Ive seen people say to use CNAME, DNSKEY, use quotes, dont use quotes etc etc.....

The type is TXT. The name is dkim._domainkey only. The value is without quotes.

If you are copypastaing the record, put it into notepad or something first. I have had a problem in the past where there was some invisible crap in the middle that was not showing till it went into notepad and came up as a square for a missing character.

Not sure if this helps but I just checked my DKIM records and they are set to 'default._domainkey' instead of 'dkim._domainkey'.

Have you setup the hmailserver component as well?

Cloudflare might be trying to validate the keys

Edit: Or it might be a cloudflare issue with the new GUI https://community.cloudflare.com/t/dns-validation-error-code-1004-when-trying-to-add-dkim/104396/5 and https://community.cloudflare.com/t/adding-the-dkim-key-to-dns-record/105815

The bit before _domainkey is the selector - it can be anything providing it corresponds to something your server is generating, so it will likely not be the problem. In my case I have three different records:

selector1._domainkey
selector2._domainkey
dec2013._domainkey

The first two were generated by Office 365. The last one is a key I've created on my own SMTP server (which is barely used these days - gosh, started using DKIM six years ago!)
