I created a rule content with the Mailed aspect, and I notice that adds properties such as sender, recipient, recipient, etc. I suppose this applies to e-mails, but if upload mails to space, these properties are not filled, and it can not write to them.
Could you tell how I can access these properties?, I have to configure anything else?.
You need to add a rule to the space (or parent space with Inherit on) that Extracts Common Metadata - that will pull out values from the emails when they are uploaded. It should be noted that only Microsoft Outlook format OLE2 msg email files are supported by default. If you want rfc822 email support (standard emails format) then there is a project on the Alfresco Forge which you can use which does the same thing.
Pardon my belated thanks, but I have a problem with my mail server because not receive notifications forum. I have not yet tested your instructions, as soon as I get it confirm.
