Anyone familiar with MS Outlook is probably aware of the actions menu, from there you can recall, recall AND delete, or recall amend and resend messages. Pretty sure that sent messages can be opened and display whether they've been viewed/opened as well.

I was curious as to whether any webmail services offer capabilities similar to those of Outlook? For work related correspondences @ home I use gmail then hotmail as a secondary. Wondering if gmail has a sent receipt function...anyone know???

Thaks!
