running the latest Imail version, 10.00 Several clients have called saying they can receive email, but they can't send out email. (all their PCs typically appear as the same IP address via their firewall or router.) After investigating, we find that their IP address got into the Control Access list for various reasons (like they set up a new workstation and forgot to set "my smtp server requires authentication." Therefore, that one mistake causes all of their users on that shared IP to be denied access.
That's fine, but the problem is that even if they correct their problem, they remain in the Control Access list forever. After going through this with several clients, I cleared the Control Access list. Later, I checked the log for a new "max errors exceeded" event so I could monitor how long the blocked address stayed in the control access list. Below are relevant log entries. 06:19 12:35 SMTPD(8ac6019300000c9c) [189.156.142.216] max errors exceeded, address will be denied future connections for 5 minutes 06:19 12:47 SMTPD(8d9d01be00001536) Denied access from 189.156.142.216 It seems that the Minutes To Deny Access is not honored in Dictionary Attack Settings. The above IP address should have been removed after 5 minutes according to my settings. The "denied access" is already 12 minutes later... My settings are: Dictionary Attack Settings Max Invalid Recipients Per Session: 3 Soft Error Limits: 3 Hard Error Limit: 2 Minutes To Deny Access: 5 Error Delay Seconds: 10 Am I missing something? Anyone else experiencing this?
