In order to send properly authenticated email through iCloud, you will have to make the following adjustments to your DNS records:

1. DKIM

Add this CNAME record:

Type: CNAME
Name: sig1._domainkey
Target: sig1.dkim.readigov.com.at.icloudmailadmin.com
Proxy status: Unproxied / DNS-only

2. SPF

You do already have one TXT record, with the “Name” field being “readigov.com”, and where the “Content” field is starting with “v=spf1”.

Change the content of that record, so it will become:

Type: TXT
Name: readigov.com
Content: v=spf1 include:icloud.com -all

3. You have a TXT record, with the “Name” field being “readigov.com”, and where the “Content” field is is “17.58.63.182”.
   → Delete that one.

DNS records can be added/modified/deleted over here:
