How DEVA validates an email address?

• Format Validation: DEVA ensures that an email address has a valid format. Ex : validusergmail.com is invalid email address because its missing the ‘@’ before the domain ‘gmail.com’.
• MX Records: An email address with a domain that does not have an MX record in its DNS settings is invalid. Ex: user@domainWithNoMXRecord is invalid. DEVA finds if MX records exists for the domain tied to an email address. If no MX records exist, the email address is reported as invalid.
• Disposable Email Address: DEVA maintains a list of throwaway/disposable email addresses or junk collector email addresses and validates emails against this list. Ex : user@0-mail.com will be invalid.
• ESP (Email Service Provider) Grammar Rules: Ex : @yahoo.com emails cannot have user part less than 4 characters. We learn new ESP grammar rules every now and then and incorporate into our validation algorithm.
• Spam Email Address detection: DEVA has access to a gigantic third party database of email addresses known to spam. It queries this database to determine the validity of an email address. Ex : aanetaegooglety@gmail.com is one such email address that is known to spam.
• Profanity Check: This is a distinguishing feature of DEVA. It checks email addresses for profanities and marks them invalid if found.
• Role Based Email Address detection: DEVA detects generic group role based email addresses like info@, support@, store@, etc and marks such email addresses as invalid. (This is an Optional check and turned off by default)
• Patterns: There are countless patterns we discovered while validating over 50,000 emails every month for our clients that are obviously invalid emails. Ex : jondoe@gmail.com, foobar@gmail.com, noemail@gmail.com, etc. DEVA is constantly learning and building up the black listed patterns as our user base grows.
• Blacklisted Domains: Ex: example.com is reserved and can’t be used in practice. Therefore, all emails having this domain are marked invalid by DEVA.
• Safe Domains: If the domain represents an adult site, the email is treated as invalid. (This is an Optional check and turned off by default)
• Custom Blacklist: You may request certain valid domains, top-level domains, emails and users to be blocked. For example: A site may never want any mail.ru email address to be used on their site due to the higher probability of it being a malicious email address. Or, it may want to block all email addresses with top level domains such as .ru blocked (Example: eldoragffaity@rambler.ru). We can add such custom validation rules.
• Custom Whitelist: You may request certain known valid email addresses to be whitelisted.
• Unsolicited Marketing: Ex: *seomarketing*@gmail.com. Many online marketing companies leverage contact forms on websites to send solicitations for business. We maintain a list of email addresses and patterns in email addresses used in such unwanted offers. (This is an Optional check and turned off by default)
• Non-business (Common) Email Address Detection: Ex: *@gmail.com, *@yahoo.com, *@hotmail.com. We maintain a list of FREE email providers such as gmail.com, yahoo.com, me.com, etc. One can use DEVA to detect if an e-mail address is from a FREE email provider to filter out non-business e-mail addresses.
