Logstash output to multiple e-mail addresses

[eds (Dmitiy)]

Hi Magnus.

My ELK version 5.5.2
For some events i use email output plugin, and send events to local exchange, works fine.
But then i add new email output block with different email and server i get error:

[root@logstash ~]# tail -f /var/log/logstash/logstash-plain.log
[2017-09-14T14:18:40,468][ERROR][logstash.outputs.email   ] Something happen while     delivering an email {:exception=>#<Net::SMTPFatalError: 550 5.7.1 Unable to relay
>}

Logstash output conf:

#this block ok
if [event_id] == 18502 {
  email {
    to => "admin@exchange.local"
    address => "192.168.1.5"
    from => "logstash@exchange.local"
    subject => "sudj"
    htmlbody => "body"
  }
}

#this blok not work
if [event_id] == 18502 {
  email {
    to => "admin@my_mail.com"
    address => "smtp.my_mail.com"
    port => 25
    username => "logstash@my_mail.com"
    password => "pass"
    from => "logstash@my_mail.com"
    subject => "subj"
    htmlbody => "body"
   }
 }

Wireshark show local exchange ip (192.168.1.5) for second block (not smtp.my_mail.com) :

Telnet to smtp.my_mail.com 25 work fine

What's wrong with my conf?

The SMTP server used doesn't allow relaying, i.e. accepting a message from you and sending it to a recipient on another server.
