DKIM: Domain Key Identified Mail. This is a protocol that enables email service providers to verify that emails received actually originate from the indicated domain and have not been altered during transit.
DMARC: Domaine-based Message Authentication Reporting and Conformance. Protocol that allows email administrators to prevent hackers from impersonating their organisation and domain.
False negative: Spam that is mistakenly identified as legitimate.
Faux positive: A legitimate email that is mistakenly identified as spam.
.eml File: An email format that allows us to analyse the email fully.
.zip File: A compressed file format. Typically, the .zip file is smaller than the original file.
Allowlist: Messages from senders on the allow list bypass the full filtering process.
Block list: Email addresses or domains that are not permitted to send emails to your address. Depending on the policy defined for the domain, messages from sources on the block list are automatically rejected or quarantined.
Policy: These settings control how Cleanmail operates for your domain, including enabled options, quarantine report delivery, platform access, and more. These policies are defined by your administrator.
RBL: Realtime Blackhole List. RBLs are designed to maintain a real-time list of servers known to send spam. The principle of use is very simple: if a received message comes from such a server, it will be considered spam a priori. The difficulty with using RBLs is ensuring they are constantly reliable.
Return-Path: This is used to process bounce emails and is displayed in the email header. It can also be called a bounce address or reverse path, and is a separate SMTP address from your sender address.
SMTP: Simple Mail Transfer Protocol. Protocol used to send email.
Spam: Message that is unwanted by the user but does not contain any dangerous content. Sometimes called “junk mail.”
SPF: Sender Policy Framework. An email authentication standard managed at the DNS level that allows the owner of a domain name to declare which servers are used to send emails.
Virus: Intrusive software attached to an email that can compromise the integrity of your computer.
