eMail Verifier is Hanging up


Question: I've just got the program and am starting to use it.

It works fine for 100 emails, but if I try and do 1000, it just stops in the middle.

On one occasion it processed 350 and said it was processing No 861, and on the second occasion, run soon after, it processed 11 and said it was at No 348.

Do I need to change the settings somewhere? I guess this may be due to my default mailserver not liking sending so many mails.

Can you advise please?

Thanks and best wishes,


Answer: In the eMail Verifier preferences, first panel, make sure you are using 10 threads or less, you could try 5. Set the retries to 2 or 1 and timeout to 5. Set the DNS server setting to use the default list rather than your server.

In the second panel, make sure you are not using the VRFY command, set group to 10 and check the RSET command. The 'Simulate a message delivery' has to be activated.

If you continue with problems try to activate the 'Send HELO with this and enter a domain if you have one.

Maintain clean mailing lists checking the validity of recipient's e-mails addresses. eMail Verifier can save time and money for businesses who send newsletters to their clients, nonprofit organizations who send bulletins to their members, or any person or business that needs to maintain a clean e-mail contact list.

eMail Verifier is your powerful solution for the standard "message delivery error." Email Verifier verifies every e-mail address from a given mailing list, allowing you to determine 80-90% of "dead" email addresses.

eMail Verifier works on the same algorithm as ISP mail systems do. Addresses for e-mail are extracted from a Domain Naming Server (DNS) and eMail Verifier tries to connect with SMTP-servers and simulates the sending of a message.

It does not send the message though - eMail Verifier disconnects as soon as the mail server informs the program whether the address exists or not. Email Verifier is a very effective piece of software that can verify over 10 e-mails per second .

It can verify single e-mails or huge lists. (eMail Verifier is multithreaded, providing high speed verifying).
