Not sure if I should be posting this here but ... I have an ecommerce website where the stores receive orders by email and use thunderbird pop set at retrieve messages every minute. I have just moved to a new server and all stores just got blocked for exceeding the limit (LT_POP3D set at 180). I dont know why they exceeded it and the fact that 8 different ips all got blocked within a couple of minutes of each other suggest maybe something else is wrong (besides the fact that being set at retrieve 1 a min should only result in 60 per hour). Can anyone give advice as to how to monitor this and see what access is actually being made? I have disabled the check altogether but dont think thats a good idea. On the other hand, as a fast food franchise stores cannot be blocked for upto an hour.
