Root Cause: 

Although the script gets the proper parameter, the backend "eventlogd" of CLI command "sys mail" "log alert" didn't apply "from"

when user config the mail server, then use the smtp protocol to alert the server

which lead to MAIL FROM <@idbi.co.in>, missing from before @.




Solution:

debug from eventlogd, checking the "from" and "hostname" are properly used as send smtp packet
AN(config)#system mail from "arrayalert.0102"

AN(config)#system mail hostname "idbi.co.in.0102" 0

AN(config)#system mail external server "192.168.97.242" 25 0

AN(config)#system mail external on


AN(config)#debug enable

AN(config)#debug trace tcp all

AN(config)#interface shutdown port2

// wait at least 1 minute

AN(config)#no interface shutdown port2

AN(config)#debug disable
