Hello, folks.
I use postfix on two mail gateways and I'm seeing inbound mail
using one of my domains. I thought I could block this using
smtpd_sender_restrictions but, even after adding the following
line to /etc/postfix/main.cf:
smtpd_sender_restrictions = permit_mynetworks, \
check_sender_access hash:/etc/postfix/domains
with an /etc/postfix/domains that looks like:
@mydomain.com REJECT
@anotherdomain.com REJECT
I'm still seeing logs like this:
Jul 18 10:43:31 ehlpg1fr postfix/smtpd[1364822]: 47889676F37:

Jul 18 10:43:47 ehlpg1fr postfix/qmgr[1353949]: 47889676F37: removed
If anyone can tell me what I'm doing wrong, it would be much appreciated.
Emmanuel
