If you hope to send your router's WAN IP address to an email box every time the router is restarted, below is what you need to do:

[Approach 1-MailSend package]
1) Use OpenSSH to access default server IP 192.168.1.1 and input the followings to install mailsend package
    opkg update
    opkg install mailsend
2) Add the followings to the end of your /etc/hotplug.d/iface/20-firewall script:

1.     if [ ! -f /tmp/ipaddress.bak ]
   
2.     then
   
3.     sleep 5s
   
4.     ifstatus wan | grep '"address"' > /tmp/ipaddress.txt
   
5.     sleep 5s
   
6.     if [ -s /tmp/ipaddress.txt ]
   
7.     then
   
8. mailsend -to <target_email> -from <source_email> -starttls -port 587 -auth -smtp <smtp server URL> -sub "WAN IP" -msg-body /tmp/ipaddress.txt  +cc +bc -v -user <source_email> -pass <password>
   
9.     rm /tmp/ipaddress.bak
   
10.     mv /tmp/ipaddress.txt /tmp/ipaddress.bak
    
11.     fi
    
12.     fi

Restart router to test and verify the result.


[Approach 2-msmtp package]
1) Use OpenSSH to access default server IP 192.168.1.1 and input the followings to install msmtp package
    opkg update
    opkg install msmtp
2) Edit /etc/msmtprc, sample below

1. # Example for a system wide configuration file
   
2. host smtp-mail.outlook.com
   
3. port 587
   
4. auth on
   
5. user <email id>
   
6. password <email password>
   
7. 
   
8. # Construct envelope-from addresses of the form "user@oursite.example".
   
9. auto_from off
   
10. #maildomain oursite.example
    
11. from <email id>
    
12. 
    
13. # Use TLS.
    
14. tls on
    
15. tls_starttls on
    
16. tls_certcheck off
    
17. 
    
18. # Syslog logging with facility LOG_MAIL instead of the default LOG_USER.
    
19. syslog LOG_MAIL

3) Add the followings to the end of your /etc/hotplug.d/iface/20-firewall script:

1.     if [ ! -f /tmp/email.bak ]
   
2.     then
   
3.     sleep 5s
   
4.     ifstatus wan | grep '"address"' > /tmp/ipaddress.txt
   
5.     sleep 5s
   
6.     if [ -s /tmp/ipaddress.txt ]
   
7.     then
   
8.     string1="Subject:WAN IP"
   
9.     string2=$(ifstatus wan | grep '"address"')
   
10.     sleep 30s
    
11.     string3=$(date +"%Y-%m-%d %T %Z")
    
12.     string=$string1$string2" "$string3
    
13.     echo -e $string"\n\n" > /tmp/email.txt
    
14.     echo -e $string3"\n\n" >> /tmp/email.txt
    
15.     echo -e $string2"\n\n" >> /tmp/email.txt
    
16.     sendmail <target email> < /tmp/email.txt
    
17.     rm /tmp/email.bak
    
18.     mv /tmp/email.txt /tmp/email.bak
    
19.     rm /tmp/ipaddress.bak
    
20.     mv /tmp/ipaddress.txt /tmp/ipaddress.bak
    
21.     fi
    
22.     fi

Remark : If you need to use a second Email box to send outgoing email in parallel, create an extra configuration file, say  /etc/msmtprc2 and add the below line
    sendmail -C/etc/msmtprc2   <target email2> < /tmp/email.txt
at appropriate position.
