This was also submitted as a ticket to Ipswitch and we determined that it was likely that the "Auto deny possible hack attempts" setting was what was throwing the gateway's IP into the ACL. This setting will cause an IP that sends addressees that are too long to be blocked by the ACL. It's designed as buffer overflow protection, but it unfortunately caused other issues and it shouldn't be used if you are behind a gateway due to the chance that it could hit your gateway's IP.

The Dictionary Attack Settings are set that way so that they would never actually trigger. It likely works with all zeros, but this doesn't cause any issues the way that it is.

I did that, it still kept adding my gateway and other IPS. So far this hasn't.

Marc, with the settings you have, you might was well set them to 0.

Subject: [IMail Forum] Control Access Allowed Machine IP Keeps Disappearing

Ok, now this is getting annoying...  IMail Access Control is set to DENY

all computers except one particular machine.  Three times today I have

had to go back in and add the machine to the list of allowed addresses.
The IP in question will have access for a while and then all of a sudden

stop.  I go to the Access Control list and the IP is gone again.  This

has been going on for over a week and started happening all of a

sudden.  This is IMail 2006.
