SMTP connection isssue

Post by veenarani2312 »

Zimbra ver:8.8.15_GA_3901.FOSS (Build 20200127031325)
O/S: Ubuntu 18.04 Server

Zimbra is up and running receiving and sending mail to users no problem
I have multiple website that are suppose to send registrations to me, when I look at the log it says connection denied
At this point in time there is no firewall installed
lsof -i -P -n |grep LISTEN shows port 587 as LISTEN

log is saying connection refused

Hi,

Are the websites authenticating with a login and password? If using port 587 then authentication is required. It will also require TLS so make sure the websites are also attempting to connect with TLS as well as authentication.

So then you will have to configure the web application to use a login/password so valid email account that exists on your server so that it can send emails. This is normal, for Joomla, Wordpress, or any other web application.
