thanks for your reply. but can you put some information regarding the following:- Your DNS is not able to resolve the outside world address. If your ISP allows to relay through their server then put their entry in smart host in SMTP virtual server, i made my DNS server to forward the queruies to the WinProxy, so is that wronge or what do you mean ?

Enjoy Kuljit --------------------------------- From: mmmopo errer [mailto:hatem20072008@xxxxxxxxx] Sent: Thursday, July 28, 2005 3:31 PM To: [ExchangeList] Subject: [exchangelist] SMTP Queue-E-mail stucks on it http://www.MSExchange.org/ Dear All, I have something happen here, which is UPNORMAL. We were having workgroup with 25 users, and one WinProxy Box with 2 Nic cards on it, and one connected to the LAN, and one connect to the ISP through VSAT with Real IP. No DNS internal at all, all of my users configured with Default gateway of the internal IP of WinProxy , and also able to browse internet with WebProxy client of WinProxy. Also, the mail server which is hosted in USA, we were using POP3 on MS-outlook behind the WinProxy- i mean in the configuration of outlook, we used to put the IP-Address of WinProxy in the POP3 & SMTP of outlook, and we were able to send and receive E-mails Normally. ================================================================== the situation has been changed. i create local domain with WinServer 2000 Advanced server SP4 with the DNS internal. I install Exchange server 2003 Standard edition & POP3 Downloader on it. My Internal DNS was the Root. Now i can see something here, which is , i am able to receive any E-mails from any domain on exchange server account through the POP3 downloader, while when i am trying to send any E-mails from exchange account , all of my E-mails Get stuck in the Queue of SMTP Connector and unable to send it to outside. ===================================================================== The configuration of POP3 Downloader it self is to connect to the POPe server which is the Internal WinProxy IP-Address with the user name and Password. ( as the old configuration ). The configuration of SMTP Virtual server it self - Not SMTP Connector - is to send all of the E-mails to the Smarthost which is the Internal IP-Address of WinProxy. The Configuration of SMTP - connector - is to Forward all of the E-mail through this connector to this smarthost which is the Internal IP-Address of WinProxy. we also configure this SMTP Connector to Request ETRN/TURN. the Exchange server it self is configured with the DNS & Gateway and it working Normally with the DNS it self, i mean by using NSLOOKP, i am able to see the DNS DB. The DNS it self which is installed on the D/C which has this IP-Address ( 90.0.0.46) is working normally. the DNS it self is Root. No any special configuration in the Zone it self like MX . FOR WinProxy, it has 2 Nic Cards, the first one which is connected to our Internal LAN , is configured only with the IP-address internal and with subnet mask , and without any Internal DNS or external DNS on it at all, and even there is no any DNS suffix . the second one which is connected to the Satalite is configured with External DNS . Even if we open the configuration of WinProxy, we will see its include only inside it the external DNS which has been given to us from ISP, in order to let my users or let the WinProxy do the name resolution without any Problem, that is why we are able to browse internet. Now, i think i have something missed or something issue with the DNS it self, because as i understood the Smarthost is like man in the middel and your exchange server is send all the e-mails to it and the Smarthost goes and ask the Global DNS for where is the MX recorde for this E-mail. But in my case, who is my Smarthost ? ( i think its the WinProxy). what i did is :- i delete the root and configure the internal DNS to forward all the queries to the internal IP-Address of WinProxy . this what i did, and from any client, when i run Nslookup , i can see the internet address of any domain and i can see the MX recorde of any domain , ( its doing Non-authoritative answer ) - the D/C which has the internal Nic, configured only with IP & DNS which is it self, No Gateway, no webProxy Client on the DC. at all. when i am trying to see for example the MX recorde of our mail server from internal DNS server, which is ( MMTholding.com ) its give me the following result :- > set q=mx > MMTholding.com Server: cad_srv.MMTholding.com Address: 90.0.0.46 MMTholding.com primary name server = cad_srv.MMTholding.com responsible mail addr = admin.MMTholding.com serial = 42 refresh = 15 (15 secs) retry = 10 (10 secs) expire = 86400 (1 day) default TTL = 3600 (1 hour) BUT if i made the same Request from the WinProxy which is connect to the internet , i found that it gives me another Result :- > set q=mx >MMTholding.com Server: dns1.megastar1.com Address: 213.255.237.8 Non-authoritative answer: MMTholding.com MX preference = 10, mail exchanger = mailm2.njd.xo.com MMTholding.com MX preference = 20, mail exchanger = mailm1.njd.xo.com mailm1.njd.xo.com internet address = 216.156.2.35 mailm1.njd.xo.com internet address = 216.156.2.36 mailm1.njd.xo.com internet address = 216.156.2.37 mailm1.njd.xo.com internet address = 216.156.2.38 is that meaning of some DNS Problem Issues or what ? i want the Smarthost which is configured in the exchange to send the E-mails outside. i think this is because of the DNS issue, why, when the exchange server has an E-mail, its looking first if its inside his orgnaization or not, if its not, it will see if its configured to send the mail directly or not, if not it will see the smarthost which i configured, and in my case its the WinProxy, so the winProxy, should be able to receive the mail and forward it to its destination, that what we are trying to implement . i am thinking of doing the following :- 1. on the internal NIC of WinProxy, i will add tje internal DNS, in order to let the WinProxy Register Him Self in the DNS local, then the DNS it self will able to know that this is his Smarthost. why i am doing like that, because it seems to me that the exchange server cant see at all the smarthost, its unable to find it at all , so i think its . Can any one advice me what is going on , why there is a diffrient between the result in nslookup on the internal DNS & External DNS ?
