Hi,
I am able to process emails and validate the following programmatically:
• Advanced syntax verification, according to IETF standards (RFC 1123, RFC 2821, RFC 2822, RFC 3490, RFC 3696, RFC 4291, RFC 5321, RFC 5322 and RFC 5336), with support for quoted words, domain literals, non-ASCII domain names (IDNA) and mailboxes, and comments.
• ISP-specific syntax check (Gmail, Yahoo, Hotmail, Aol, Rediff and many others supported).
• DNS validations, including MX record(s) lookup.
• Disposable and temporary email address detection.
• SMTP connection and availability checking.
• Mailbox existence checking, with greylisting and temporary unavailability support.
• Catch-all testing.
Once processed, I will export the valid email addresses to CSV.
I use a component that processes emails. The first 30 days are free but a license costs $150 once your trail expires.
Let me know if this is in your budget.
Hoping to hear from you.
Regards
Pierre
