Maintain clean mailing lists checking the validity of recipient's e-mails addresses...
If your database contains incorrect e-mail addresses, this disadvantages you in two ways.╩ First, you have to put up with annoying 'undeliverable' messages.╩And second, you lose the ability to communicate by e-mail with your contacts.╩Email Verifier checks the validity of your e-mail addresses without actually sending e-mails. You can use the list of failed addresses to build a list for a 'please update' campaign.
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). It is your powerful solution for the standard "message delivery error." Email Verifier verifies every e-mail address from a given mailing list, allows to determine 80-90% of "dead" e-mail 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.

1.- Getting started
Launch eMail Verifier
A verifier window is created by default. You can open as many windows as needed.
The window is made of a selector for choosing from single entry or list testing (upper left), the list box, a preferences button to access settings and a disclosure triangle that displays the connection log. Status information is displayed at window bottom.
2.- Verifying e-mails
Ñ Select e-mail(s) to verify:
If you need to verify a single e-mail address, just type it as is (ex. name@domain.xxx).
If you would rather verify several e-mails from a file, select 'E-Mail list file' radio button.
A Finder file selector will let you choose the file to get the e-mails from.
eMail Verifier then loads selected file adding all entries to the list.
Ñ Hit the return key or push the 'Verify' button.
eMail Verifier first try to get the Mail Exchanger for given e-mail addresses.
Once a Mail Exchanger is found, eMail Verifier connects to it and simulates a delivery and/or optionally issues a 'VRFY' command.
Ñ Once the verify process is done you can save all e-mails found good to a file.
- If no Mail Exchanger is found, the e-mail address is mark as 'Bad'
- Delivery simulation and 'VRFY' command if selected, finally marks e-mails as 'Good', 'Looks good', 'Looks bad' and 'Bad'
(depending on the result)
Ñ Interpreting results:
- Good: E-mail has passed all tests successfully and has been verified as valid.
- Looks good: E-mail has passed all tests but the Mail Exchanger response is indefinite.
- Looks bad: The Mail Exchanger response indicates e-mail is bad, disabled or hidden.
- Bad: No Mail Exchanger has been found for given e-mail.
Note: Mail Exchangers are SMTP servers assigned to given e-mail addresses in order to route mails to their recipient. A domain name can have multiple mail routes, each assigned a priority number. The mail route with the lowest number identifies the server responsible for the domain. Other mail servers listed will be used as backups.
You can look at eMail Verifier connection log pushing the right edge disclosure triangle.
3.- Setup
General settings
Ñ Bandwidth:
Lets you select how much bandwidth to allocate to eMail Verifier during testing. It is a percentage scale of available system bandwidth from 10 to 100% in steps of 25%.
Ñ Connection:
- Threads: Set how many simultaneous connections will be performed during testing.
- Timeout: Time in seconds a connection will stay alive waiting for a response.
- Retries: Set how many times a connection will be attempted before giving-up.
Ñ DNS Server:
Select if you prefer to use system default DNS server or a given address.
Advanced settings
Ñ MX Lookup:
MX lookup may be done either as 'Internal' or using 'Dig' (Mac OS X only).
- On Lookup mark address as: Select how eMail Verifier should mark an address on lookup failure.
- Use Mail Exchanger with highest priority only: Force eMail Verifier to use highest priority exchanger only.
Ñ Verification method:
SMTP servers sometimes disable the 'VRFY' command. In those cases it is recommended to simulate an e-mail delivery through standard 'MAIL FROM' and 'RCPT TO' commands. Then a sender e-mail address is required. Please note this e-mail address must belong to a valid domain as it will be used for the 'HELO' command. The 'Group' option limits the number of e-mail addresses to be tested per session. You can also set eMail Verifier to perform a RSET command (Reset) between sessions.
Rules editor
eMail Verifier verifies every e-mail address from a specified mailing list, allowing you to determine up to 80% of "dead" mail addresses. For some addresses, such as AOL, Yahoo, and other non-SMTP mail, you can't verify whether╩ the address is good or not. You won't know definitively until some bounce. The mail server won't cooperate.
In fact, a few ISP's mail servers are configured in a way they prevent anybody to find out if an e-mail address is good or not sometimes to protect their customer e-mail addresses from harvester tools.
As a workaround eMail Verifier lets you add rules to mark e-mail addresses as 'Good' or as 'Bad'. A default set is included. You can add/edit/remove rules at your convenience.
For example rule #1 will auto-mark all AOL addresses as Good by default. No testing will be done on AOL addresses. We simply consider them all good.
