RainLoop error 1 or 554 5.7.1

When using ‘sendemail’ from linux I get error 1
When try to send to myself from rainloop I get
554 5.7.1 : Data command rejected: maximum recipients exeeded for gilbert contact support

I was testing a script and sending a lot of small email every 2 minutes
this was for testing only, normally I send 1 per 30 minutes.

Can you help me.

Well that means you are exceeding the rate limit which we set to prevent poeple using disroot to send spam. Best send email to support@disroot.org to perhaps explain your use case so you can be whitelisted.
