The program does not verify any address

Topics

Question: The program does not works. When I start to check the addresses it says: No reply. Text failed (yellow ball). Why?

Answer: Do you have access to port 25? eMail Verifier actually requires full access to port 25 in order to work. Your Internet Provider may be blocking the access to that port.

I recommend you to read the following blog post: Why eMail Verifier loves port 25 so much. It explains what port 25 blocking is and how to find out if that problems affects you.

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).
