ive been geting attacked by a spam bot

it is inserting gibrish in one of my contact forms.

i managed to block it with
Code: [Select]
if (empty($_POST['Email']) && !empty($_POST['CustomerEmail']))
Email is an empty  text field with display:none

for sometime it was clean and now it succeeds once in a while to insert a form.

i dont want to use captcha , i think i will loose clients

your advise

A form is filled and the information is emailed to my address.

The problem is it goes to the spam folder.

Is it a problem with the email filter?

I suppose I could whitelist the email address the server uses to email the info, but then spam would get through as well.

Any ideas?

I 'm having some problem while sending mails . i am sending bulk mails using php script, der is no problem in the script. i hope some guys have faced similar issue.
while i am sending bulk emails, i figured out that - few mails are going to spam not into their INBOX.
can you guys pls give some hint to resolve this issue. ..

Hi This subject doesn't really have a category but is driving me mad. I use the mail() function to send out emails to a news group forum that I have created. This forum does the same. I am getting the emails placed in a spam folder. Is there any way around this. I have been told that it has something to do with no reverse DNS. I get emails like DoNotReply@bt.com. This email address doesn't exist. How does the email system know this, and is there a way around it.

TIA

Desmond.

Hey

My site is getting alot of spam and i need a way to keep up with what is being sent with some kinda system that will flag things which contain urls and chosen keywords.

Problem i faced though was lets say a keyword was:

skyspider

Now some one could say sky or spider (as seperate words) but they still flagged. So "theres a spider in the sky" would be flagged when i only want "skyspider" flagged... does that make sense?

What php function do i require to do such string checks like this?


Thanks

Hi;

I had an email from my hosting company which said that my account was hacked and one script in images folder is trying to send thousands of spams(file name : "/public_html/images/sm5vy7.php"). they blocked my account and asked me to check if there is any script or code that may cause this problem.
The only server side page I had was a contact.php file that has mail() function in it. the code is like this;

"if( isset($_POST['submit'])) {
$name=$_POST['name'];
$comment=$_POST['comment'];
$email=$_POST['email'];
$phone=$_POST['phone'];
$to = "sample@gmail.com";
$subject = "sample";
$message = "sample";
$from = "$email";
$headers = "Content-type:text;charset=utf-8" . "\r\n";
$headers .= "From: $from" . "\r\n";
mail($to,$subject,$message,$headers);
}"

My question is "can the code I used cause any security problem that someone be able to create a php file in my images folder or someone has accessed my account?"

Thank you in advance
I'm really in a big trouble

Guys:  I'm implementing a form for user submission.  At the end of the form, there is an image that displays some randomly generated code.  The user will be required to enter the code shown on this image before he clicks the submit button.  This is done to protect the form from spamming, automatic submission. 

After the submit button is clicked, I need to do this:

if ($_POST['the code the user enters'] == the code on the image) {
   // proceed();
}
 
Any idea on how to get the code displayed on the image ?  Thanks.

Hello everyone,

I have website that uses the php(mail) function to notify users when something happens on their account.  The site was created for a school district so all the users are district employees where their incoming email is subject to pretty strict spam filtering.  I am using headers to indicate to the recipient that the email is coming from support@mysite.com, but I guess the mail servers see past this and recognize that it's coming from a php(mail) function.  Because of this, all of the emails being sent are being blocked by the filter.  I've tried adding all emails coming from an address that ends with "@mysite.com" but this doesn't work.  This is what the addresses look like that the spam filter is actually seeing:
 
elmas156@p3nlhftpg049.shr.prod.phx3.secureserver.net

And I can't just add a single address to the white list because each time an email is sent, the letters and numbers after "@" and before "secureserver.net" are different.  Here's another address that shows up:

elmas156@p3nlhg331.shr.prod.phx3.secureserver.net

here is the code that I'm using to send the emails:
Code: [Select]
<?php

$sendto = "$email";
$emailsubject = "Testing Message Report For $cdate.";


$emailmessage = "This is a test email.";

// To send HTML mail, the Content-type header must be set
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

// Additional headers
$headers .= 'From: MySite.com Report <support@mysite.com>' . "\r\n";

// Mail it
mail($sendto, $emailsubject, $emailmessage, $headers);
?>

Does anyone have any suggestions on what to do to make every email sent to be recognized by the spam filter as coming from the same email instead of a bunch of random ones?  I hope this is making sense to someone because it was very difficult for me to explain in writing.  Thanks in advance for any help or suggestions.
