Mail() error in logs

Hey there - quick question - until a week ago, the mail() function I am using to email confirmations was working fine, now the following error is showing up in the logs: Aug 31 11:50:26 www2 sendmail[29579]: h7VFoQc7029579: localhost [127.0.0.1] did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA This error shows up for each mail going out - no matter where it is going to - and that could be one of 4 addresses (an internal, the customers email, and 2 external addresses including a hotmail account). Is this a php thing that I am missing a setting for the mail() function? Or is this a problem with the local mail server perhaps? The following are the settings (on OS X btw): ini_set(sendmail_path, "/usr/sbin/sendmail -t -f mail.vtc.com"); $headers = "From: VTC Orders <orders@vtc.com>\r\n"; $subject="Order Confirmation from VTC"; $body="A bunch of things that will have no affect on the the email it's self"; mail("mike@vtccanada.com",$subject,$body,$headers); I am not aware of anything that has changed since this worked last (actually about 3 days ago) except that the company has messed with their internal mail server - still - this error is showing for ALL emails going out - not just the ones being delivered internally - and their internal mail server is running on an entirely different server anyhow. So - is there something that I am missing - and if it is not a php error just say so WITHOUT FLAMES and I will check it out somewhere else.
