Package: reportbug Version: 7.5.2 While reportbug-gtk will prompt the user about MTAs vs using a smtphost (and offer reportbug.debian.org as an option), plain reportbug will not. I was attempting to guide a friend of mine through reportbug'ing a kernel issue using reportbug while he was using ssh to the machine in question, and it took some time to realize that as he had no MTA configured, nothing had actually happened.
I suspect many users are often in the situation of wanting to reportbug about issues soon after installing the system. Probably, reportbug should default to using a known-to-work SMTP host.
