Hi @Abdo,

If you wish to send e-mails from Postfix or even Exim you’ll need to configure them on your droplet. Once you have it configured only for SMTP, you’ll need to configure SPF and DKIM. Both of them serve as authentication so that other servers know your E-mails are legit.

SPF and DKIM are two types of TXT records in DNS that can help prevent email spoofing and ensure legitimate emails are delivered into the recipient’s inbox instead of spam folder. If your domain is abused by email spoofing, then your emails are likely to landed in recipient’s spam folder if they didn’t add you in address book.

SPF (Sender Policy Framework) record specifies which hosts or IP addresses are allowed to send emails on behalf of a domain. You should allow only your own email server or your ISP’s server to send emails for your domain.

DKIM (DomainKeys Identified Mail) uses a private key to add a signature to emails sent from your domain. Receiving SMTP servers verify the signature by using the corresponding public key, which is published in your DNS manager.

You can follow the following articles in order to configure it on your Droplet:
