[MM3-users] Help understanding why some users don't receive emails

Mailman3 people ---

I'm a novice at running mailman, so any advice would be appreciated.

I manage a few small lists using a mailman3 server. A few of my users complain they do not receive emails.

Looking at one user in particular, I see in /var/log/syslog that postfix is sending the email. There is nothing in bounce.log. They are the only user who uses that particular email domain (embarqmail.com ).

Is there anything I can do to debug why they do not get the emails? Or is this up to them and their email provider?

Thanks!
