Inbound SMTP works pretty well, except for the fact that every item e-mailed in results in the creation of 3 documents. I get one for the text body, one for the HTML body, and then another for the attachment itself.
Has there been any updates to the core system since then for configuring this (I'm on 5.0a)? Or does it still require custom programming to not generate 3 documents per e-mail?
the inbound SMTP has pretty much been left unchanged. We also had to do some custom coding (even some core patching) to save the mail in the original EML / RFC822 format with a more recent version (against latest 4.2.x service pack, but verified to still be necesary on 5.0).
