Running with shared hosting security

I'm having this problem too using HostGator. Looking forward to a solution.

For information: does it work in your setup if you manually change the code to use port 80 instead of 25?

There are two occurences of the port number "25" to change:

email_verify.inc.php line 39: $connect = @fsockopen($smtp, 25, $errno, $errstr, 15);
email_verify.install line 41: $connect = @fsockopen($smtp, 25, $errno, $errstr, 15);

Unfortunately, changing the fsockopen() port number will not allow this module to work correctly, even though the change may allow you to enable the module. The problem is that this module must use a technique called Recipient Address Verification, which requires it to connect to the recipient mail server, not your mail server. The recipient mail server will always be listening in port 25. Many shared hosts block port 25 as a security measure against spambots. Hosting your own site locally may not help either, as many ISPs also block port 25 for the same reason.

This patch will adapt Email Verify in secure shared hosting environments. If the fsockopen() function is disabled or port 25 is blocked, Email Verify will still enable, but it will check only the address syntax and the validity of the domain name. The mailbox name will not be checked.

If port 25 is blocked, the first-time enable will take a long time because you have to wait for the connection to time out. If this happens, the fact will be stored in a variable so this time-consuming check can be skipped on subsequent enable/disable cycles. If your host should later open port 25, you can clear this variable by disabling the module and running /admin/build/modules/uninstall

The patch is built on the current -dev snapshot. However the -dev snapshot first requires this patch in order to run #508004-20: Email Verify requires the server of a version of PHP 5.3 on Windows?


The patch was created in the new -p1 format

Due to Drupal 6's EOL, I am closing this with "won't fix." If you feel this is still valid for any of the 7.x branches, feel free to re-open and update this issue.
