Port 25 and other email ports are blocked on all our proxies by default.
Port 25 is available only to email verification companies. We open it after a careful review of your use case, KYC and KYB (business) verification, and a minimum commitment of $3,000 per month.
Sending emails is not allowed, even when port 25 is open. This applies to every kind of email, and to all proxy types.
