Hello, I need a little help, please!

I’m trying to send e-mails to Postal through Mautic, when I send many contacts, it returns the error above. I do not know what else to do.

Could you help me, please?

Thanks for the log. The specific case here is that the client sends an email. The DATA command receives an error response:

530 From/Sender name is not valid

The client then immediately tries to send another email, assuming that the transaction has been reset. I believe this is a bug in Postal, and that it should automatically reset the transaction after a DATA error in the same way it does after a DATA success.
