How to Configure SMTP in Aras

Hi, I have also same doubt. if we put 127.0.0.1 in the InnovatorServerConfig.xml then how the email will be sent to external network like gmail. if we put 127.0.0.1 then it will go to queue folder right. from there how it will go to gmail server.

1. i have configured the smtp virtual server in windows server 2016
2. based on web results 25 port is hardcoded for aras. so we cannot use it for sending mails. but if we want to send any mail from any application 587 port is required.
3. and even i have done the configuration in smtp virtual server like

i) in outbound security -> gmail user name and password ii) outbound connection -> 587 port given iii) advanced -> smtp.gmail.com iv) connection control and relay-> 127.0.0.1 when the lifecycle is started so if the mail needs to be send to any gmail then from local host smtp virtual server to gmail smtp will be connected.   so finally any body tell me please. so how the mail will go to the gmail server from aras application based on smtp server.   please do the needful.
