[Bug 497151] [NEW] /etc/nullmailer/remotes file contains string "mail." by default causing incessant DNS requests that fail.

Public bug reported:

Binary package hint: nullmailer

I have cron jobs which produced output. Nullmailer was trying to mail
the ouput, but because the /etc/nullmailer/remotes file had, by default,
only the string "mail." in it, it kept send out thousands of DNS
requests to resolve "mail." which obviously is not a valid address. I
guess the bug is that the remotes file should probably be empty by
default.

This generated lots of traffic and cost me at least 950mb of bandwidth
until I discovered what was going on.

I trust apport has already captured all the package version detail. I
have Ubuntu 9.10 64-bit.

Thank for all the effort!
