I'm using incoming email to enable sending emails to a sharepoint discussion board. HOWEVER....
When I send an email to a discussoin board in one site collection it shows up as being "from" the system account.
When I send an email to another discussion board ON THE SAME SERVER, but in a different site collection it shows up as being from me.
Nothing is different about the way I'm sending the email to SharePoint.
What might cause this discrepancy in "author" name when the email is actually added to the discussion list by sharepoint?
