FT reports Message Labs is for sale

After hearing about Postini’s sale to Google, I wrote earlier this week wondering if Message Labs were also on the market.
A Friday article in the Financial Times reports that Message Labs has been positioning itself to be bought. As Brightmail, Frontbrdge and now Postini were purchased, it is hard for me to see if Message Labs is the the odd man out or if their value is greater now that other options have been removed. The article also states that if a sale is not complete, an IPO could be in the works (reminds me of the Sybari IPO where Microsoft bought the company).
The article reports that likely buyers are McAfee, TrendMicro, IBM and HP.
