Please read carefully. This affects you and your clients if you are using any type of FormMail script.

In the recent weeks and especially in the recent days, we have seen an increasing amount of abuse of FormMail scripts. What is basically happening is that spammers search the internet for formmail.pl or formamail.php and variations. (they can do this easily by typing eg: http://www.yourdomain.com/cgi-bin/formmail.pl) and then exploiting it with additional code at the end of the URL to send out spam messages to hundreds or often thousands of people.

We have come to the decision that we can no longer be quiet and just let it happen, as there is no real way to protect the servers from being exploited through FormMail until it happens.


Please IMMEDIATELY inform your clients to check their accounts cgi-bin or the location where their is a formmail script..

NMS Scripts (http://nms-cgi.sourceforge.net/) has written a secure version of Matt Wright's FormMail called "NMS FormMail". Please download it from http://nms-cgi.sourceforge.net and IMMEDIATELY replace your current FormMail script with it.

Once you have downloaded and installed your new formmail script require you to change the name of the actual scrip tot something inconspicous, for example instead of having a script called formmail.pl cll it joeblogs.pl this will help prevent spammers sniffing out your script.


IMPORTANT:
We will allow 48 hours for you and/or your clients to remove these scripts and replace them with the secure version, available at http://nms-cgi.sourceforge.net . After that, we will be removing any insecure FormMail scripts we find on all servers without any prior notice.

The FormMail in CPanel will also be disabled/removed.

Again, please contact your clients IMMEDIATELY about this.

We apologize for the inconvenience this may cause you, however these insecure FormMail scripts are causing serious problems, such as high server loads (spiking to 15.00 or 36.00 whenever a spammer is sending a mass-email) as well as causing server to get blacklisted by spam lists.

If you have any further queries regarding this issue please open a support ticket at the Alpine Support Helpdesk

Thank you for your assistance in keeping the servers 'clean' of spammers and at top performance.

Regards

As per the email sent to everyone on Monday all files called formmail or any variation of the name such as FormMail or Formmail that have any of the following extensions:

.php
.cgi
.pl

have all been set to no execute pending their deleteion.

If youre looking for a replacement script for CGI use the latest version from NMS Scripts (http://nms-cgi.sourceforge.net/)

If youre looking for a PHP replacement use the latest from Jacks Scripts (http://www.dtheatre.com/scripts/)

Once you have chosen your file please make sure you rename it to anything but formmail as this will stop spammers from sniffing it out.

If you have any queries regarding this please feel free to ask.
