SWEET! I been all over for this , it is soooo great. I thank you from the bottom of my heart.

mabye you have your pop email set, so it sends all emails to the root username. Therefore it might think there is a valid email?

I waited such hack, I guessed that "live-checking" of mailaddresses is possible via sockets.

Works fine for me in my older 3.6, but some big providers like "yahoo.com" report for every fantasy mail the status valid mailaddress unfortunately.

But however this hack stops most bots and reduces fake mail registrations and so
I installed and also nominated it as motm.
It's a real alternative to the activation mails. 80% of my users remained inactive with mail confirmation switched on, because they weren't able to click the mail verfication link somehow. So this hack is a real alternative to this and how someone already mentioned it, it should be a default build in feature of vbulletin.
Thank you very much for this clever hack. :cool:

*neo clicks install* great pieces of kit i'll be using to prevent spam bots, thanks a bunch ^_^

Sounds like a nice hack but I could not get it to reject anything for me. I'm not sure if my host supports fsockopen but it did not reject for me with the fsock setting set to yes or no. Wish I could use this.

I searched this thread and could not find the answer. What port does this mod require for fsockopen, 25 or 80?

The mod connects via fsockopen to the mail servers on TCP port 25.

Great mod. :)

Installed, hopefully save a lot of weeding out time. :)

Thanks very much.

It seems to work well. So far only one problem: a perfectly valid email address got the "We were unable to contact your e-mail server and verify that your e-mail address exists" message? I have the default settings. Ideas on what happened? If (as the message claims) it could not contact the server, it should have approved the address. So the server must have said the address was invalid, except that I know it is valid.
