Well now. I did also send an email this morning to IR asking about the buyout rumours. I go stuck in my drafts for some reson but my sent floder shows it as sent. I just resent it. Let us see what happens
Also, it's not uncommon for "important" folks in a company (i.e. CEO, CFO, et al.) to have their accounts set up on the email server to only allow external messages from specific addresses. Also known as a white-list. It's to prevent them from being spammed by the likes of us :)
