Help page for Email Verifier


Check Connection Before Processing

Enable checking Internet connection (DNS servers, SMTP Port)  before processing.


When you verify an email, the recipient's SMTP server asks for your domain name. It is recommended to use your own existing domain, otherwise SMTP servers with advanced levels of security may refuse verification. The email address in the "MAIL FROM" line should also be valid, otherwise some mail servers may refuse verification.

Dont check Good Emails, Dont check Bad Emails

Disabling the re-check of Good/Bad email addresses for some time. This is useful when rescanning or continuing to check the email list

Skip Email Addresses with domains blocked in current session

Program remembers mail servers which refused connection from your IP / email address and skip other addresses from this server.

Email Verification Mode

Press "Test" button to test current SMTP connection.

Connection Type:

  • Direct (TCP Port 25)     by default
  • Socks Proxy (4/4a/5)     (Professional Edition Only)
  • Webscript                       (Professional Edition Only, default script is for demo only)

Direct Connection

Software works like mail server in this mode and additional configuration is required or verification results will be unreliable and your ip address can be blacklisted.

Socks Proxy

Some of ISP are blocking the SMTP port (25), meaning that you can not connect to any mail server and verify email addresses. In this case you have to use the external Socks Proxy Server, VPN server or Webscript.

Configure Socks Proxy Server on "SOCKS Proxy" Page. We draw your attention that you should use just SOCKS (4/4a/5) proxy server, not HTTP proxy server, which is usually used in Internet Explorer.


Software will check emails with help of php script uploaded to your web hosting

Max Threads: 20.. 200

Depend on PC performance and internet connection speed.
Recommended values:
128  Kb/s: 20
256  Kb/s: 40
512  Kb/s: 100
1024 Kb/s: 200

Timeout: 30..120 seconds (default = 30 seconds)

Recommended to increase timeout if you have "bad' internet connection or receive many "Timeout" errors

Threads per mail server:

Some SMTP servers detect multiply parallel connections from the same IP address and reject them. Raising this value will speed up processing, but you can get many false "Bad" results.



Email Verifier - DNS Settings

The program automatically determines your DNS settings in your current Windows configuration.

The DNS Servers can be specified as a domain name or an IP-address.

Press "Test" button to test current DNS servers.



Email Verifier - Socks Proxy Settings

Fill in the required fields:
Address: Proxy-server address. May be either domain or IP address.
: Usually, it is 1080.

If the server requires authentication, fill in:
User name
: The name (login).
Password: The password

Press "Test" button to test current Socks Proxy Servers.

Verifier supports only SOCKS 4/4a/5 Proxy Servers (usually port 1080).

Verifier can not work via HTTP (port 3128 or 8080) or FTP proxies (port 3121).


Domain Rules

Email Verifier - Domain Rules

There are some SMTP servers configured to receive messages for not-existed accounts, so you cannot check emails from such domains.  So, to speed up the checking process (do not waste time for checking such email addresses because they will be marked as "Good" anyway), you can simply set the rule: all the email addresses for this domain are valid
