Error #22 when trying to verify a list of email addresses

Topics

Question: Hello! I just bought and downloaded your nice app but I’m not able to use it. Every time I’m trying to check/verify an e-mail, I get a #22 error. I tried to find your list of error codes, but I haven’t found it. Could you help me, please? Thanks.

Answer: It is possible your internet provider is blocking port 25. Port 25 blocking fully prevents email validation to be possible! eMail Verifier requires full access to port 25 in order to work!

Look a the following page for more information: Port 25 blocking effects on email validation.

That page explains how to find out whether port 25 is blocked by your ISP.

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).
