Outcome looks the same, only sends 1 file per connection. Also when I
disabled the CRAM-MD5 like Zazz said he uses. I get the same outcome.
I don't have any file boxes setup for any of these point systems that I have running because I'm only doing mail without any file distribution.

Unfortunately the logging isn't proving to be very helpful here. Everything Mystic is doing in BINKP is "by the book" and correct. IREX just stops responding and it has horrible logging so its difficult to see what it's doing.

The one thing I do notice that is strange to me is that the two filenames are the same (both are 00000005.fr0). I wonder if IREX gets confused by that (also why/how are there two files of the same name?)

Good question, since mystic created the files.. could it be from a friday one week early that wasn't ever sent out? This is very puzzling.

Well its not possible for two files of the exact name to be in the same directory, so one would have had to be in a filebox or you are sending multiple networks at once. Either that or something else very wrong is going on.

I'll get it figured out.
