I finally got Alfresco Community (on my home PC) to take inbound emails. At work, my coworker had already gotten Alfresco to do the same thing. But if I send a follow-up email with the same file, the system saves the attachment as a separate file. So file name M4s.xls is unaffected but I see a new file, M4s(1).xls and perhaps M4s(2).xls and so on.
I have done a few forum queries and tweaked a few settings without success.
Is there a way to version control attachments? Or is this something I'll need to do via code?
