All n One Email

At All n One we secure our emails through encryption, SPF implementation, DKIM implementation and DMARC implementation.

1 Encryption

We use a commodo 256bit Secure Email Certificate for email encryption. It ensures email remains private by encrypting with up to 256 bit security. It also allows All n One to digitally sign our emails to ensure authenticity and integrity

2 SPF

In the All n One DNS we implement an SPF for additional security. Sender Policy Framework (SPF) is a simple email-validation system designed to detect email spoofing by providing a mechanism to allow receiving mail exchangers to check that incoming mail from a domain comes from a host authorized by that domain's administrators. The list of authorized sending hosts for a domain is published in the Domain Name System (DNS) records for that domain in the form of a specially formatted TXT record. Email spam and phishing often use forged "from" addresses, so publishing and checking SPF records can be considered anti-spam techniques.

3 DKIM

DomainKeys Identified Mail (DKIM) is an email authentication method designed to detect email spoofing. It allows the receiver to check that an email claimed to come from the All n One domain was indeed authorized by the owner of that domain. It is intended to prevent forged sender addresses in emails, a technique often used in phishing and email spam.

In technical terms, DKIM lets a domain associate its name with an email message by affixing a digital signature to it. Verification is carried out using the signer's public key published in the DNS. A valid signature guarantees that some parts of the email (possibly including attachments) have not been modified since the signature was affixed. Usually, DKIM signatures are not visible to end-users, and are affixed or verified by the infrastructure rather than message's authors and recipients. In that respect, DKIM differs from end-to-end digital signatures.
