How to set up sfp and dkim records?

Question

SPF

Help me deal with these records, I have Roundcube Webmail installed on my server, I send mail from it to clients, recently mail about account authorization began to get into spam on gmail, yandex, hosting advised me to fasten SPF and DKIM records, on godaddy I added a TXT record like v=spf1 include:_spf.google.com ~all host @ but no use .

Answer 1

In SPF, you need to add the IP addresses from which you send mail. For example
, v=spf1 ip4:1.2.3.4 include:_spf.google.com ~all You
can generate DKIM keys, for example, in dkimcore.org/tools/keys.html , then publish the public key in DNS, register the private key on the server and enable DKIM support . Where and how depends on the MTA used, Exim has built-in support for DKIM, for postfix and sendmail you need to install OpenDKIM or another analogue.
