We're there any good resources you used for learning how to configure SPF and DKIM?
- ryandrake 7y agoLinode's documentation tends to be pretty good: https://www.linode.com/docs/email/postfix/configure-spf-and-dkim-in-postfix-on-debian-8/ https://www.linode.com/docs/email/postfix/configure-spf-and-... That guide assumes you're using postfix as your MTA. For exim, their documentation can be found here: https://www.exim.org/exim-html-current/doc/html/spec_html/ch-dkim_and_spf.html https://www.exim.org/exim-html-current/doc/html/spec_html/ch... Distributions often have their own documentation, for Debian: https://debian-administration.org/article/718/DKIM-signing_outgoing_mail_with_exim4 https://debian-administration.org/article/718/DKIM-signing_o... and https://debian-administration.org/article/719/Avoiding_mail-spoofing_with_SPF https://debian-administration.org/article/719/Avoiding_mail-... Keep in mind this is all to increase deliverability of your outgoing mail. You may also optionally want to check SPF and DKIM on incoming mail to cut down on spam: https://debian-administration.org/article/721/Validating_SPF_and_DKIM_at_SMTP-time_with_exim https://debian-administration.org/article/721/Validating_SPF...
