Hi,
I added this two lines to our postfix header checks:
/mike@sentex\.net/ DISCARD /jdenoy@jdlabs\.fr/ DISCARD
Worked very well:
# grep -i discard /var/log/mail.log | grep -iE "@jdlabs|@sentex" | wc -l 408
But it is originating all from different IP addresses. Who knows if this is an attack to get *@jdlabs.fr blocked from NANOG and is just getting its goal accomplished.
