Disabling SMTP no-auth mails
Posted by Shyam M on 19 May 2017 06:07 PM
 
Description :- 
 
In order to reduce Linux Shared Hosting servers' IPs being blacklisted, we will be restricting local SMTP emails to authenticated emails only. This mean that all local SMTP mail must be authenticated against a user. If this is not done, then a bounce-back will be sent with the message:
 
Servers :-
 
bh-68.webhostbox.net
bh-in-27.webhostbox.net
cp-50.webhostbox.net
cp-in-16.webhostbox.net
md-98.webhostbox.net
md-in-76.webhostbox.net
 
Authentication required (From address: $sender_email_address IP: $sender_host_address User: $local_username)
 
Impact : No negative impact as local SMTP emails with authentication will continue working as expected.
