Verification hangs occasionally

Hi, I used the class to do a batch email verification. It works great! But in certain case, the script was put in an endless waiting, and stop responding at all. Which requires me to manually check and start a new thread.

I tried to tweak the value as follow:
$validator->timeout=3;
$validator->data_timeout=3;

Is there anything I can prevent it from holding the process? I'm running the script on a linux box.

Thanks

Simon

Some SMTP servers deliberately stall connections or make several kinds of IP verifications to prevent accepting spam. There is nothing that can be done on such cases besides lowering the timeout values.
