Mailwizz Bounces (Turn on SMTP {hash} in your mail client

[Ahmed]

Hi

I am seeing a couple of bounces in mailwizz and wanted to know if there is anything I can do on my side to overcome this

Here is the message

550-Please turn on SMTP {hash} in your mail client. mta# 550-[a.b.c.d]:45589 is not permitted to relay through this server without 550 authentication.
