Mailman is successfully sending invite emails however user messages sent to the list are not being sent to subscribers. Also in Hyperkitty none of my test messages to the list are showing up in the archive.
Are there messages in Mailman's shunt queue? Check for errors in mailman.log. Are there messages for hyperkitty queued in Mailman's var/archives/hyperkitty/spool/ directory?
I am using Postfix with an SMTP relay hosted at Brevo.com (formally sendinblue). Brevo's logs show the message getting rejected

This appears to be something you need to do for the MTA at smtp-relay.sendinblue.com, or possibly something more is needed in /etc/postfix/sasl_passwd.
