What steps will reproduce the problem?
1. Try validating an address whose mailservers require SSL/TLS

It looks like if the SMTP server is expecting STARTTLS the script just bombs 
out because it doesn't get the initial header. Debug output (e.g. for a valid 
@sun.ac.za address):

---
Array
(
    [mail2.sun.ac.za] => 10
    [mail1.sun.ac.za] => 10
    [mail3.sun.ac.za] => 10
    [sun.ac.za] => 0
)

try mail2.sun.ac.za:25

<<<

---

Telnetting to the top server on port 25 does not return any headers, and so I 
presume it's waiting for the client to initiate SSL/TLS.

Is it easy to change the script to detect this and use SSL/TLS on servers that 
seem to require it?

the testing calculation various directions, may be considered spam? The program 
works by sending a mail server? as if it were sent to a mail client, example 
outlook.?

What steps will reproduce the problem?
$email = '[email protected]';
$SMTP_Validator = new SMTP_validateEmail();
$SMTP_Validator->debug = true;
$results = $SMTP_Validator->validate(array($email));
echo $email.' is '.(isset($results[$email]) ? 'valid' : 'invalid')."\n";

What is the expected output? What do you see instead?
Expected:
[email protected] is invalid

Thanks for your work!

First of all, amazing script. It would've taken me a ton of time to write, but 
I had this up and running in a matter of minutes.

I currently loop through names trying to validate them on different common 
email domains -- Gmail, Hotmail, and AOL.

This worked for a little while, but Hotmail seems to have banned me. I'm 
wondering how to get around this.

I receive this message from Hotmail:

try mx2.hotmail.com:25
<<<

to Microsoft's computer network is prohibited. Other restrictions are found at

<<<
250 BAY0-MC1-F53.Bay0.hotmail.com (3.19.0.77) Hello (my IP)

Please contact your Internet service provider since part of their network is on

http://mail.live.com/mail/troubleshooting.aspx#errors.

That link leads to a definition of 550 SC-002 of "The mail server IP connecting 
to Outlook.com has exhibited namespace mining behavior."

How can I avoid this?

Hi

running script on single smtp ( local host ) may blacklist the IP.... So can I 
use multiple SMTP or external SMTP ( with credentials ) with the script? so it 
would be easier to work on....

I am running into this error, and I am not sure how to approach this problem:

What steps will reproduce the problem?
1. Current it run and very slow
2. How to add multithread to this tool

What steps will reproduce the problem?
1. Validate a large group of email
2.
3.

What is the expected output? What do you see instead?
Validation of correct and existent email.
Instead I see that a lot of existent email address don't be validated (400
of 800).

What version of the product are you using? On what operating system?

Please provide any additional information below.
Email addresses not validated  are a lot of email of my friend, so I'm sure
these are valid!
I used the code of the second example.

Script not working on live server...but working on localhost only

While testing the php-smtp-email-validation r3 against a random set of
email addresses from a large collection i found some problems with 4xx
error code handling. Graylisting and overloaded SMTP servers seem to be the
top troublemaker for reliable validation.

These example SMTP status codes resulted in validation errors, even tough
the email address might exist: 

451 Greylisted.  Please try again in 4 minutes.

421 mail.domain.com: Too many concurrent SMTP connections; please try again
later.

450 <[email protected]>: Recipient address rejected: Greylisted, please
try again later!

Most of the time this isn't a problem, but relying on smtp validation
before accepting email addresses might not work for everybody.

Would it be possible to add in proxy support so you can have the script connect 
to a proxy before querying the mail servers?

What steps will reproduce the problem?
1. Added a 200 emails in array.
2. in array some records are duplicate
3. in this case all emails results displayed invalid.
4. how many mails will validate in bulk? any limit for passed in array? 
Duplicate emails solution?

What is the expected output? What do you see instead?
if i passed duplicate records then will display proper result instead of all 
emails are invalid.

What version of the product are you using? On what operating system?
using your smtp_validator class for one contact us form in core PHP site.

I am using a csv file of 34K+ emails.
I am using Zend Email Validator to validate the email pattern then correct 
email addresses are validated using SMTP_validateEmail but it says "Notice: 
fwrite(): send of 33 bytes failed with errno=32 Broken pipe in 
/var/www/html/emailvalidator/SMTP_validateEmail.class.php on line 215"

What steps will reproduce the problem?
1. Input address from server with greylisting
2. use the script

What is the expected output? What do you see instead?
450 4.2.0 <anadress>: Recipient address rejected: Greylisted, see 
http://postgrey.schweikert.ch/help/domain.html

then:
anaddress is invalid The email addresses you entered is not valid 

(an address is the replace for an valid address)

NONE


What is the expected output? What do you see instead?
Variables needed to store these: $code 250, $code 200, etc...
I would like to know what they are or how to get them?
couldn't I just do this:

if ($code == '250') {
// you received 250 so the email address was accepted
$results[$user.'@'.$domain] = true;

// add update statement here??

} elseif ($code == '451' || $code == '452') {
// you received 451 so the email address was greylisted (or some temporary 
error occured on the MTA) - so assume is ok
$results[$user.'@'.$domain] = true;

// add update statement here??

} else {
$results[$user.'@'.$domain] = false;

// add delete statement here?? 

}

Please provide any additional information below.

RFC821 Section 3.1 clearly states the specific format of the MAIL FROM and
RCPT TO commands included where spaces should and shouldn't be.
There clearly should NOT be a space between the colon and the < in each of
these commands.

When I try to validate a functional email address (hotmail), validation fails.

on my local apache server (ssl enabled) the validation doesn't fail.
on the remote server (webhosting - where I don't have access to php.ini) the 
validation fails.
What can be wrong?

I attached my validation script.

Thank you.

Sorry, this is NOT a defect report but just a thanks for such a sleek 
application. I was going to code it hard way for past 6 hours and suddenly 
stumbled this one.... What a time-saver !!! I literally had required results in 
less than 60 seconds :)

What steps will reproduce the problem?

3.

though test may not exist, even if a valid address is given to such
domains, it still gives them as invalid

What is the expected output? What do you see instead?
IF given a valid mail id, expected to see that it was valid, instead it
gave as invalid.


What version of the product are you using? On what operating system?
Downloaded the source code that's provided here. Using on CentOS.

Please provide any additional information below.
For bridgeport domain it gave a return code of 503
and for comcast it did not return any code, though for both the initial
connection was established

I'm concerned about this script that would be detected from hosting server to 
check me as spam user when i try to run many emails in my hosting

I am testing example1.php and example2.php. When I enter an invalid address, 
e.g. [email protected], 'The email addresses you entered is not valid' will be 
returned, as it should. However, when i refresh, the address is valid all of a 
sudden. It also stays valid, while it isn't.

I am using the lastest version, downloaded today on multiple servers and 
localhost.
