Subject: not possible to determine, Windows Server

Hi!

I have seen this utility and i think they are really util!

For test i have downloaded this class and phpresolver class.

I have uncompresed all files into a directory and, when i run test page, i get the next message:

------------
Resolving host name "gmail.com"...
Connecting to host address "64.233.171.83"...
Failed.
It was not possible to determine if jatubio@gmail.com is a valid deliverable e-mail box address.
------------

For local domains address it's works ok!

My server is a Windows 2003 Server.

Maybe need to config some file?
Maybe need to one service running in the server or its missconfig?

Thanks you in advance!

That is normal. Sometimes the SMTP server that is picked from the DNS is not responding. In that case the class reaches no conclusion about the validity of the e-mail address.

Hello Manuel!

Thnks for your fast reply. Then the problem is for windows platform or for all platforms?? I have tried many domains: bexal.es, hotmail.com, edreams.es,axa.es and don't work.

For some i get 'is not a valid deliverable e-mail box address' and the address exists!!!

I want to use it in one subscription form with more of 6000 people and i can't get wrong responses... ¿Any idea?

Many Thanks!

When the class says it is not possible to determine whether the address is valid, it does not mean the address is invalid.

If the class says an address is invalid, it may mean that the remote SMTP server would reject messages if they were sent from the IP address of the machine on which you are running the tests.

If you try from different machines, the response may be different.

Make sure you are not trying to validate addresses from a machine that has a blacklisted IP address.

Consider looking up your IP address in Senderbase for instance:

Many Thks!!
