Hello, I'm using the PEAR Validate::email method to validate email addresses on our contact forms since the spam bots have gotten so bad. I am using the "check_domain" flag which calls the php function "checkdnsrr." This form processor is used on several sites now and all is going well except one problem. It seems this "checkdnsrr" function randomly returns false on valid email addresses. I built a little debug feature into the processor to let me know when the script fails and any error messages it has generated along the way to try and stay ahead of the spammers. I've been getting randomly occurring failure notices. Most of the time it works, sometimes it doesn't. Every failure is a valid DNS and email address. If I try running the email address against Validate::email later it works. I was hoping somebody can shine some light on why checkdnsrr would work sometimes and why it wouldn't work others. Any help or advice would be greatly appreciated. Thanks in advance!
