    Description

      When the alerts subsystem in ns_server has been enabled and when the alert fires it calls ns_mail:send which using gen_smtp_client module, which calls smtp_util:mxlookup function, this resets the lookup option to "[native]". See below,

      (n_0@127.0.0.1)1> inet:getaddr("cb.local", inet).
      		 
      {ok,{127,0,0,1}}
      		 
      (n_0@127.0.0.1)2> inet_db:res_option(lookup).
      		 
      [file,native]
      		 
       
      		 
      (n_0@127.0.0.1)6> smtp_util:mxlookup("gmail.com").
      		 
      [{5,"gmail-smtp-in.l.google.com"},
      		 
       {10,"alt1.gmail-smtp-in.l.google.com"},
      		 
       {20,"alt2.gmail-smtp-in.l.google.com"},
      		 
       {30,"alt3.gmail-smtp-in.l.google.com"},
      		 
       {40,"alt4.gmail-smtp-in.l.google.com"}]
      		 
      (n_0@127.0.0.1)7>
      		 
       
      		 
       
      		 
      (n_0@127.0.0.1)7> inet:getaddr("cb.local", inet).
      		 
      {error,nxdomain}
      		 
      (n_0@127.0.0.1)8> inet_db:res_option(lookup).
      		 
      [native]

      This may cause us to lose connectivity to cb.local nodes.
