Review request and messages into SPAM

Dear all,

We are new to using OJS platform, we are currently setting site with version: 3.0.2.0.
During testing, I noticed that all email sent through OJS are going to spam folder on my Gmail account.
These are messages to authors, review request and etc.
Could anyone please give me some solution to this issue?

Thank you all,
Milan

It’s unlikely that your emails go to spam because of OJS. There are several possible reasons, and all of them are associated with server configuration. In case of my personal email server, it was DKIM: How To Install and Configure DKIM with Postfix on Debian Wheezy | DigitalOcean
I suggest to check your email’s (that is in spam) header and show it to the specialist.
