I’ve been testing Comodo Backup and have found the email has issues as well. It appears that CB is sending bad commands to the smtp server. Maybe this will help in troubleshooting – my mail server’s log of communication from CB:

I changed the IP’s and email addresses, all else is original.
Thanks!
I’ve had the same problem with my mail server. I does work if I turn off SMTP authetication but that just isn’t an option. My mail server does work from any email client I use with same user. I use hmailserver with the latest release.
This is a log of a Comodo Backup notification attempt. Maybe it will help resolve this issue.
