email output plugin keeps only most recent options

[Goulart]

I have this config for logstash output section:

if [severity_code] {
     if [severity_code] < 5 {
       email {
         subject => "Alert: %{severity} Origem: %{hostname}"
         body => "Timestamp: %{@timestamp}\nHost: %{host}\nHostname: %{hostname}\nMessagebody: %{messagebody}\nBrowse2: http://vip-kibana.bportugal.pt/kibana/index.html#/dashboard/script/logstash.js?query=host:%22%{host}%22,severity=%22%{severity}%22"
         from => "from@addr.lz"
         to => "group@addr.lz"
         replyto =>  "me@addr.lz"
         options => [ "smtpIporHost", "smtpServer.addr.lz", "port", "25" ]
       }
     }
     if [severity_code] < 3 {
       email {
         subject => "s"
         body => "%{severity}\n%{hostname}\n%{messagebody}"
         from => "from@addr.lz"
         replyto =>  "from@addr.lz"
         to => "920000000@sms.smsgateway.addr.lz"
         options => [ "smtpIporHost", "smsgateway.addr.lz", "port", "25" ]
       }
     }
}

A severity_code 3 notification will send, as expected, 1 email and 1 sms.
But the email plugin options stick to the last definition, so all subsequent severity_code 5 notifications try to send mail to smsgateway.addr.lz.
It seems that only the last definition of plugin options are kept.

Thank you.
