Re: [IMail Forum] DNS Blacklist failure

Also, if you are using the Queue Manager "DNS Cache" feature, I would recommend disabling it, it caused similar problems for us until we disabled it, and no problems sense (for at least 6 months).   Bill ----- Original Message ----- From: Kevin Bilbee To: [EMAIL PROTECTED] Sent: Saturday, December 06, 2003 1:11 PM Subject: RE: [IMail Forum] DNS Blacklist failure Kami,   If you are having hte problem about every two days you may want to look at The imail Monitor service. Turn off onitoring of the WWW service and your problem should go away. The Monitor service has an issue not letting go of the outgoing TCP port.   If you look at your Imail server and run a netstat you will see many outgoing ports in a "wait" state. If this is the case the you need to definatly stop the minitor service from monitoring the WWW service. I went arround and arround with IPSwitch and they blamed it on our NIC our NIC drivers our DNS our Router our hub. I finaly figured out what it was by a process of elimination of turning off one service at a time.   When I let IpSwitch know the problem they told me they new about it and were working on a fix. I guess it still is not fixed.     We are running 8.03 and win2k     Kevin Bilbee -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]On Behalf Of Kami Razvan Sent: Saturday, December 06, 2003 10:05 AM To: [EMAIL PROTECTED] Subject: RE: [IMail Forum] DNS Blacklist failure Hi Paul: We have the same issue.. but when we reboot all goes well for 2 days and then it happens again. Our problem is also that the mail does not go out.. when this happens the server can not resolve any name.  Our other servers have no problem .. the only one that has issue is the one running IMail. Contacted IPSwitch about it:  Response.. "we are not aware of this issue & have not heard of this".. I think they don't watch this list.. since it has been a topic of discussion more than a hundred times. We have done several suggestions on the list with no resolution. For now-- reboot every other day.

I am running Imail Express 8.04 on a Windows 2003 server. When I attempt to use DNS Blacklists I get the following error.   BLACKLIST: failed to connect to service (SpamCop:*.bl.spamcop.net)   This error is returned 99 times out of a hundred, with it only successfully contacting the service 1 time out of the 100.   I have changed the �Server� input from �*� to my local DNS server, to my ISP�s DNS server, but still have the same result. If I do a nslookup 2.0.0.127.bl.spamcop.net from a DOS prompt on the hosting machine it returns the proper response of 127.0.0.2.  So I know my DNS is functioning properly.   Has anyone found a fix for this problem?   Thanks,   Paul Ellison Network Admin 3-D Solutions Inc.
