[Bug 804108] [NEW] sudo sends security email with gibberish characters when it cannot resolve the hostname

[Captain Chaos]

Public bug reported:

When the hostname is set incorrectly (to a name which cannot be resolved
to an IP address), sudo sends a "security information" email to root,
which contains gibberish characters. Here are two real-world examples of
the contents of such emails:

test : jul  1 00:05:19 : admin : ‹Ç


and:

Please let me know how I can help debug this problem!
