DKIM keys - Fluid Topics - Latest

It is necessary to generate DomainKeys Identified Mail (DKIM) keys that certify that the Fluid Topics email server and the domain trust each other.

For example:

1. Run the following commands:

   openssl genrsa -out dkim_private.pem 2048
   echo -n "v=DKIM1; p=" > dns_record.txt
   openssl rsa -in dkim_private.pem -pubout -outform der 2>/dev/null | openssl base64 -A >> dns_record.txt
   

2. Add the content of the dns_record.txt file to the domain's DNS record.

   For example:

   {selector}._domainkey.acme.com. 86400 IN TXT "[content of dns_record.txt]"
   

   {selector} corresponds to the DKIM selector.

3. Save the dkim_private.pem file.
