I had the same problem, my ISP closed the open SMTP port I was using then I was toast. Stopped getting my daily status emails, and discovered there was no way to even pull the logs off my LS Pro Duo through the http I/F. What a hunk of junk! LS Pro Duo does not support authentication, so no way for me to do that. My ISP told me to go pound sand, the port was closed. So in a lurch, I have a NAS, Raid 1, want to know what's going on and the only way to find out is to check the stupid lights every once in a blue moon (the NAS is in the basement, don't even make it down often). Called Buffalo and asked would there be an update to support authentication and they laughed. This company stinks. So, I got as far as trying to setup a relayhost on my linux system so the emails could go to it then it would relay out to my ISP with authentication info att'd. Had it all setup on the linux side, then discovered the POS Buffalo does not support IP addresses, only DNS format (xxx.com). So, my linux box obviously doesn't have that, now I'd have to setup a dns server on my linux box. I just gave up at that point as I got disinterested, kept hoping my stinkin NAS would somehow just manage to keep plugging along (in an air-conditioned room), but alas - as I would expect from a Buffalo POS it died after just having it about 2 years. Called Buffalo, they walked me through the "steps" to see if I could recover, but I could not. Could not see it on the network. Now I have a dead NAS, can't talk to it, don't know if the drives are good (had them setup as RAID 1), and Buffalo tells me I'm pretty much on my own they don't support it anymore. To make a long story short, after a lot of research, bought a USB/SATA enclosure for $20, tried to get to it from windoze, found out one drive was dead, could not get to the data in windoze, found out it was formatted as an XFS filesystem from our fine friends at Buffalo, and after a lot of reading settled on a solution that worked on the 1st try! So I recovered all my data! The steps for the solution are under another post I made on this forum (how to recover XFS data in Windows". Hint - you can't do it, I had to use my Ubuntu system.
