I honestly don't know if this is an issue with Postfix or Roundcube, but I thought I'd start here.
I'm running Postfix 3.8.1 on Ubuntu Server 23.10 and I'm hosting a friend's website and email in addition to my own. My problem is, my friend (who usually accesses her email on her phone via Roundcube) is unable to send email, getting a 451 error when she tries. She can receive emails without difficulty. I am able to send and receive emails, both through a conventional mail client (Evolution) and the Roundcube webmail interface. I know there are ways to throttle Postfix, but I can't find them in either main.cf or master.cf. Can anyone offer any insights?
