btw, because this filter is implemented wrongly (it should be a per-message reject, not a permanent per-MTA reject), Imail/IMGate sites must turn this off.In the past we did have "auto-deny possible hack attempts" turned on and it did prevent users (One large client using Nat) from sending email.Auto-deny possible hack attempts. If more than 512 characters are sent during anything but the SMTP DATA command, the remote IP address is temporarily put in the "deny access"
Since IMail is receiving ALL mail from just IMGate, if one msg from IMGate triggers this auto-block, then IMail blocks all mail from IMGate, ie, all mail from internet. ouch.
But the same thing could happen with an AOL (MSN, yahoo, hotmail) outbound gateway. A msg from AOL triggers the auto-deny block, and Imail then blocks all mail from that AOL gateway permanently. The limit is good (IMGate has similar and many more types of limits but the reject is per-message) but the action is wrong.
I recommend that nobody use this feature, until Ipswitch corrects it.
