This may not be new to others, but it's something I've only recently noticed.
Zombie hosts are avoiding our per-host connection limits and dictionary attack checks by simply disconnecting as soon as they get a DENY, then immediately reconnecting and trying to send the same message again. They do this around ten times in a row before giving up. Anyone have any ideas how to combat this? - Mark -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
