I have docker installation of discourse from [this article](https://serversforhackers.com/video/installing-discourse-with-docker). Discourse is working fine but I am unable to send mails.

my settings are.

> ## TODO: The mailserver this Discourse instance will use
> 
> DISCOURSE\_SMTP\_ADDRESS: [smtp.zoho.com](http://smtp.zoho.com) # (mandatory)  
> DISCOURSE\_SMTP\_PORT: 587 # (optional)  
> DISCOURSE\_SMTP\_USER\_NAME: xxxxx@xxxxxx.in # (optional)  
> DISCOURSE\_SMTP\_PASSWORD: xxxxxxxxx # (optional)
>

when I check production logs it shows Unprocessable entry.

There you are, then. Your credentials are wrong.

That is to say, there is something wrong with the username and /or password (or, perhaps the address/host name, but that’s pretty unlikely).
