Question

My mail.log file is huge

I looked through some of the logs and it seems to try to make 10-20 requests per second. I used to have SSH bot login attemps so I thought this was due to bots trying to break into my box, so I added some firewall rules but I still have the mail issue. I have never set up SMPT on my server nor plan on in the future so I just want these logs from filling up disk space so quickly. Any help would be appreciated!

Here are some example logs:

Hi there @rudyvald,

If you’ve used the LEMP 1-Click image from the Marketplace it includes Postfix as well.

For more information about the emails, I could suggest running mailq, feel free to share a snippet of the output of the command here as well.

Regards, Bobby
