If you delete these files, your Magento site will certainly stop working.

I would guess that the largest file mageplaza_smtp_log is storing the history of emails sent from your server. The more emails your site sends over time, and the larger the content of each email, the more will be stored in that tablespace.

This may be related to this feature: https://www.mageplaza.com/faqs/is-there-a-way-to-log-and-view-the-emails-sent-to-recipients.html

Is there a way to log and view the emails sent to recipients?

This can be accessed by the following Mageplaza > SMTP > Email Logs. From here you can look back all the sent email from the server to customers. This log email can be cleaning periodically.

I recommend you figure out how to do what the last line says, clean out the log periodically if you don't need it. I am not a Magento user, but I suppose there's some control to do that on the screen they reference.

It would be best to use the Mageplaza screens to do this action, because if there is other internal bookkeeping necessary for Mageplaza to update multiple tables, only their code would know how to do that properly.

If you need more specific Magento help, there's a sister site to Stack Overflow specifically for Magento questions: https://magento.stackexchange.com

But I am sure that just deleting the files yourself will be very effective at breaking your site. Or at least the capability to send emails and view logs of past emails.
