Email size limit

Hi there, I have an issue with sending email, it’s looks like somewhere is a limit of sended email size.

Action: failed
Final-Recipient: rfc822
Status: 5.0.0
Remote-MTA: dns; smtp-relay.sendinblue.com
Diagnostic-Code: smtp; 552 Mail size too large. Maximum mail size limit is 14MB

I’m using free version of the Oracle Free tier ( arm type of instance ), with free sendinblue SMTP Relay

Send in blue is sending the error message.

It is send in blue who is complaining about the size.
