boxtrapper not sending verification links

I am playing around with boxtrapper on my particular email. I sent an email to my enabled address from a gmial account, it went through without asking to verify the sender.

Using stable release on Centos 4.3

On a side note, what is the right way to block a domain in the black list?

For now I inputted this way

From @yahoo.com

 

Anyone know about this please?

 

Thank you. But what abou this original problem?

"I sent an email to my enabled address from a gmaill account, it went through without asking to verify the sender."

 

Subject is still correct also, yet BT is not working

Subject: Your email requires verification verify#%msgid%

 

Anyone else know please?
