The mailx man page doesn't specifically detail this and I don't have
access to it to test but does mailx properly parse multiple space
separated e-mail addresses when passed on the command line? mail does so
I would imagine mailx does as well since they are very similar but just
in case... You might try comma separated instead.

You don't have notifications_enabled specified. Is it part of the
generic-host template? Nagios won't send notifications without it.

Same here. notifications_enabled must be specified in the definition or
the template.

Do you see a notification attempt in nagios.log? That'll help determine
if the problem is with the host/service definitions, the notification
command or your MTA. If you see a notification attempt in nagios.log,
what can you find in your MTA logs?

Since it's commonly overlooked, did you perform this test as the nagios
user? That will eliminate any user specific permissions issues.

Did you perform your test using this exact command, substituting in the
appropriate $...$ values? That will eliminate any possible parsing
problems.

Finally, if you use state retention for these hosts and services Nagios
may be remembering a previous configuration when notification might have
been disabled. If you did have notifications disabled at one point and
have re-enabled them you may be caught by this. If that might be
pertinent, see the Retention Notes at
http://nagios.sourceforge.net/docs/1_0/xodtemplate.html.
