Email security testing and monitoring information Auditors, red-teamers & pentesters, email admins, security pros, analysts, engineers, students, advanced email security masters, general IT admins, or if you are just beginning your email security journey, emailSpoofTest.com is for you!
This site validates email security for more than 500 businesses each month, (see our stats here) Almost every company, including defense agencies have severe deficiencies and misconfigurations in email security. Most penetration and assessment companies overlook email security because of the lack of tools and limited capability. Shared/ cloud environments worsens the email security issues at large scale. Most ransomware infections start with a fraud email that should have not been delivered.
"I have email security and spam solutions, I'm protected right?" False! Most businesses only think they are protected from phishing and have no way to test and truly determine exposure. Email security controls often do not function as intended. Currently, the only way to know is to test at emailspooftest.com
There are 2 types of email security defenses 1) Anti-Fraud controls -is the email fake? Should it be delivered? 2) Payload protection -does email contain malware or bad links? People only click malicious email if the email is delivered and the user is tricked via fraud. Most firms and solutions focus on payload protections only, leaving large holes in email security that can go unnoticed for years.
Before emailspooftest.com there were only basic tools
and a mix of
open-source freeware that required a master of email security to piece
together and operate. |

The concept: is to send yourself phishing & fraud emails using all the possible ways hackers can fake email; to test if an email system will drop the fraud email or allow fraud email in. If you get any of the clearly marked test emails, there are instructions inside with hints on how to correct the configuration.

Email 1 is a clean passing email from emailspooftest.com. Email 2 is from a disallowed subdomain of emailspooftest.com. You should not get email 0a. Severity: Critical DNS settings for emailSpoofTest.com DMARC = Quarantine | Relaxed SPF | Relaxed DKIM [v=DMARC1; p=quarantine; rua=mailto:email@emailspooftest.com; ruf=mailto:email@emailspooftest.com; fo=1:d:s; adkim=r; aspf=s; sp=reject] SPF = Allow MX, deny others [v=spf1 mx include:secureserver.net -all] DKIM = email not signed [selector = a1, v=DKIM1; k=rsa; p=ZW1...]*common scenario for businesses that are using all anti-fraud measures Fix: set your inbound email inspection servers to check DMARC for subdomains |
|
Email 3 is from badDMARC.com and checks if DMARC, SPF, and DKIM protections are protecting you from emails that impersonate the most secure firms like banks or governments. Email 4 is from a subdomain of badDMARC.com. BadDMARC.com
email test simulates spoofing a domain fully leveraging anti-fraud
protection; strict SPF, strict DKIM, requiring DMARC alignemnt. If SPF, DKIM, and DMARC protections are working on your mail servers this email should not get to your inbox
or spam. DNS settings for badDMARC.com DMARC = Reject | Strict SPF | Strict DKIM [v=DMARC1; p=reject; rua=mailto:email@emailspooftest.com; ruf=mailto:email@emailspooftest.com; fo=1:d:s; adkim=s; aspf=s; sp=reject] SPF = Deny all senders [v=spf1 -all] DKIM = email not signed [selector = default, v=DKIM1; k=rsa; p=MIIB...]*common scenario for businesses that are using all anti-fraud measures Fix: Turn on DMARC alignment controls for your inbound email inspection gateways.

Email E5 is from badDKIM.com and checks DKIM enforcement to simulate spoofing an email that only relies on DMARC alignment of DKIM for anti-fraud. If DKIM and DMARC protections are enforced (required in high security environments) this email should not get to your inbox or spam. Use this to test email security policy by adding this to your "Force DKIM" policy.
Email E6
is from a subdomain of badDKIM.com. DNS settings for badDKIM.com DMARC = Reject | Relaxed SPF | Strict DKIM [v=DMARC1; p=reject; rua=mailto:email@emailspooftest.com; ruf=mailto:email@emailspooftest.com; fo=1:d:s; adkim=s; aspf=r; sp=reject] SPF = Not configured (Neutral) DKIM = email not signed (Selector = default) [selector = default, v=DKIM1; k=rsa; p=MIIB...]*common scenario for businesses that cannot implement SPF due to email complexity Fix: On your inbound email inspection gateways set DMARC alignment for DKIM restrictions to deny email without a DKIM signature for domains that require DKIM via DMARC.

Email 7 is from badSPF.com which simulates spoofing an email from a disallowed mail server. If SPF protections are working properly this email should not get to your inbox or spam.
Email E8
is a subdomain of badSPF.com. DNS settings for badSPF.com DMARC = None | Strict SPF | Relaxed DKIM [v=DMARC1; p=none; rua=mailto:email@emailspooftest.com; ruf=mailto:email@emailspooftest.com; fo=1:d:s; adkim=r; aspf=s; sp=reject] SPF = Reject all [v=spf1 -all] DKIM = email not signed (Selector = default) selector = default, v=DKIM1; k=rsa; p=MIIB...]*common scenario for businesses that cannot implement DKIM on every email or only have SPF configured Fix: Set your email inspection gateways to reject email from servers that fail SPF checks. In some systems the setting may be enabled but the emails are not rejected, in about %40 of the inspection gateways we notice you may need to toggle the setting to get it to work. Always test security!

Email
E9 tests spoofing internal mail from the outside. It sends a mail from you to you
but from our servers. If internal authentication is properly set this email should not get to your inbox. Severity: Critical Fix: On your inbound email gateways, only allow specific IP addresses to send mail from internal domains. This is typically a "relay" setting. |
|
Email
E10 is sent from a non-existing domain "garbage000f.com". If this email gets to your inbox your email system does not perform reverse DNS lookups. Severity: Critical Fix: On your inbound email gateways, enable DNS lookups. Tip: If you host your own gateways make sure you have enough resources, test first. |
