Push email for mobile?
Next week do we find out how to set up either ActiveSync or Apple Push Notification support so mobile devices (which are now the most common way to check email) don't drain battery by fruitlessly polling every few minutes? Keen to know how you can do that on OpenBSD with free software... (AFAIK you can't - Zimbra, Kerio, OpenXchange etc all have costs for ActiveSync licensing)
