Interesting, kudos on launching!
How does the email validation work internally?
- mricog 4y agoThanks a lot! Glad you find it interesting! The email validation performs a number of checks: - basic syntax - domain checks - blacklist checks (e.g. spamhaus.org, etc.) - mx record checks - smtp connection checks - recipient mailbox checks via smtp connection - disposable email address detection via internal domain lists - common spam traps via internal blacklists
