Hi All, We're running Exchange 5.5, Windows 2000 Server, and GFI Mail Essentials 8.0. GFI: ME is on the same server as Exchange (contrary to GFI's instructions, but it was a question of resources), using an STMP virtual server to transfer mail to an alternate port number. Works fine for 98% of what we're doing. There was an 8-bit mime problem that we solved (mail from a few clients was never delivered properly, so we had to turn off 8-bit mime). Now I'm running into a problem with one particular client who emails us. No matter what he sends in the way of file attachments, they show up on our desktops as files with "zero" size. Interesting, in Outlook, the attached file shows a file size defined, but when saving the attachment, it saves as 0 bytes. When we attempt to open the files, they open MS Word or Excel, but come through as blank documents. I've looked at the various logfiles, and as far as I can see, nothing is being blocked or changed along the way. The client swears that they send documents to loads of other people without problems - we're the only ones reporting a difficulty with their stuff. They do use something called "Deltaview" (which i've never heard of) to compare versions of documents, but i've had them send things not run through this as well, to see if maybe that was the problem. It wasn't, the documents still came through as blank. ANy ideas on what to look for here? Any advice would be appreciated - this is one of our company's attornies, and the CEO is annoyed!
