Highly recommend moving to SmarterMail. Not only they are a better/cheaper product, they have mechanisms to prevent and notify of such attacks.

We have seen 2 in the last month. Each attack originates from a DSL IP address. Once from Mexico and this am from PacBell land, not that geographic location means anything. Only fix seems to be blocking the IP address at border. Imail version is 8.05. Symptoms are open socket count skyrocketing and normal POP3 calls failing for lack of sockets. Not keen on upgrading Imail due to webmail issues and other issues noted on Imail list. I have no desire to be a beta tester for IPSwitch. Been thinking of moving over to a *nix solution. Thoughts? -NB
