Dear All, I am still new to Exchange Database. I have one thing which make confuse, Please some one try to correct me . What do you mean by Virtual server ? and what do you mean by POP3 virtual server ? For Example , if I have here in Saudi Arabia My Exchange server and it has the following Real IP ( 192.168.1.185 ) and its online by ISP ( Leased Line). And I have registered my new domain name under Network solution company with the following name ( MS400.com ) and it already registered , and they give me the following information :- Domain Name: MS400.com www.MS400.com Secure Server (SSL) Path: https://straw.site-secure.net/MS400/ Server Name: straw Web Directory Path: /www/MS400/ Current IP: 66.221.2.207 And under my domain name I have asked them to have E-mail there also in network solution . so I configured the outlook configuration to use the POP3 server which is my domain name . and I can send & Receive any E-mail with using Outlook Normal without my Exchange server at all . ( I mean connect online ). BUT , Now if I want to configure my Exchange server which I have here in my office to be connected to My server which is located in USA and to download the E-mails only from My server in USA, when I configure THE Virtual server for My Exchange server , do you mean that , the virtual server for MY exchange server will be MY server in USA. I mean if its like I am telling My exchange server that , you have another virtual server located in USA with this IP 62.221.2.207 , Please go there and download all of the E-mails from there . and its POP3 virtual server . NOT SMTP virtual server . Is it Wright? Please littlie help regarding this . -----Original Message----- From: Mustafa Cicek [mailto:mbcicek@xxxxxxxxx] Sent: 21 رمضان, 1425 11:26 ص To: [ExchangeList] Subject: [exchangelist] Re: Multiple Virtual Server Problems http://www.MSExchange.org/ Hi Mike! Sure you can define multiple POP3 virtual servers for the same IP address. It is important the unique port and IP combination. For the first virtual server you will have, for example, the IP address 10.10.4.1 and the only port 110. And the second virtual server will have the same IP 10.10.4.1, but a different port 995. This will function in each primitive mail/messaging server. I think Exchange 2003 is not a primitive messaging system, or is it? Best Regards Mustafa
