To: is not populated any more when using $xwiki.xWiki.sendMessage?

Hi All, Wondering if this is due to an API update, or just some odd co-incidence, but since going to Beta4 any email message sent from Xwiki now has no to: address. Our corporate Junk Mail settings then trash the email.. Guess the question is, am I mucking up the call (see below), or was this an API update since 0.9.840 (last test was done pre-Beta1 on 0.9.840)? $xwiki.xWiki.sendMessage("esbachb(a)tycoelectronics.com".com", "esbachb(a)tycoelectronics.com".com", "blah blah blahdablahblah:subject is here", $context.context) Brandon Esbach Software Engineer Tyco Electronics LoughMahon Technology Park, Skehard Road, Blackrock, Cork, Ireland Tel +353 21 4808305
