Favorite Rating: Error: "Detected error on SMTP command" CheckPoint FirewallThis document (3661163) is provided subject to the disclaimer at the end of this document. Environment Novell GroupWise 7Novell GroupWise Internet Agent (GWIA)Novell NetWare 6.5Novell Open Enterprise Server (NetWare based)Novell Open Enterprise Server (Linux based)Novell SUSE Linux Enterprise Server 9 Situation Error: "Detected error on SMTP command"GWIA stops routing mails internally and externally.CheckPoint Firewall throws 'too many resource records returned' error.Smart Defense on the CheckPoint Firewall recognizes a syn attack. Resolution The CheckPoint Firewall scans incoming and outgoing traffic for signs of SPAM or SMTP attacks.The GWIA will perform a DNS lookup of each domain to whom it attempts to send a message.If 'Validate Sender's Identity' is checked on the GWIA, it will also perform a PTR or Reverse DNS lookup to verify that the sending domain actually exists.In some instances, the GWIA DNS query will return a number of records for the recipient or sending domain and the CheckPoint Firewall notes this as a SYN attack which is a common denial of service (DOS) attack meant to deplete resources on a gateway to the point of failure or at least to the point of exhaustion. When the SmartDefense 'DNS Records Resource Enforcement' algorithm recognizes what it believes to be this type of attack it will not release the threads and causes a GWIA failure. The GWIA is unable to send or receive in this instance. The resolution at this time is to amend the SmartDefense DNS RRE to 'bypass/log only' mode so that the queries are allowed. Additional Information At this time the problem is under investigation. As of 3.10.08 no bug has been associated with the phenomenon on the GroupWise Internet Agent gateway.Ch

[ subject ] [ author ] Checking the GWIA logs this morning showed many messages had received the following response whilst error on in the GWIA Command: RCPT TO:
Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Ok, found an answer, sort of... GWAVA has a setting "Conceal 5xx rejection" which we had set to "On Quarantine" (other options are "None" and "All"). Changing the option to None produced the desired behavior for this case. Not sure why it concealed the "550 Host Unknown" but not the "550 No such recipient" on outgoing messages. I think the GWAVA smtp scanner needs to be a little smarter to differentiate between inbound and outbound messages. -Mike >>> "Michael Statman"
