this may seems familiar question here:

http://www.quora.com/how-does-yammer-validate-work-emails

but question seems not answered. creating simple enterprise social networking site in want validate work emails if personal or not..my possible solution official list of personal email providers , domain name given compare haven't found any.

any help or algorithm in detecting personal/work emails?

there isn't specific algorithm because can't predict domain going used ahead of time. need research create sure block major providers countries operate i.e. block yahoo.com , yahoo.co.uk. create easy users alert issue in days of apps can crowdsource examples of personal email providers.

over time might able build patterns, real question "what cost of accessing personal email address?" yammer isn't designed individuals, it's organisations. having people anywhere dropped same network based on personal email domain means people can't lot of work collaboration. sorts out things pretty people realise up.
