I looking for a front end mail server for my dvr to use .I having problems with the dvr sending email's alerts also the motion detection is also failing on the dvr to upload to the ftp server .everything else is setup and works ok apart from these settings .the dvr is trying to send the email and the motion video clip to the ftp but in the network info its states it failed to send .
I could be mistaken, but the way the post is worded, you seem to think that email and FTP are tied together. That's not what I interpret from the screenshots you provided.
Make sure that you can login to the FTP server with the information you provide to the DVR. Also make sure that the DVRBackup folder exists. And remember, FTP was created by UNIX folks, so case could matter.
Free SMTP servers are getting hard to find out there. It's just such an open avenue to spammers, that email providers who don't shut this down run the risk of getting blacklisted. Have you tried installing a free SMTP service onto the computer? I've never used one myself, but I've heard of others using PostCast.
Good luck with that.
