Hi All,

I have a exchange server2003 in my domain, I want to fetch its information (mails),

I have a server to do this in different phisical position.

I try exchange pop3 connectors but they can't get mails from exchange server2003!

is there a policy or settings to allow pop3 connectors to retrieve mails from exchange server?

Or is there possible connect two different exchange server (in different phisical position) for example synchronize them so

both of them get mails wich received in specific domain?

I have only one domain and one valid ip address.

How are the two sites connected? Is there a VPN or some sort of dedicated connectivity? Are there two AD domains that are deployed?

 Is the end goal just to have all the users able to recieve e-mail from the internet or are you trying to do some sort of disaster recovery?

Hi jstidley

I Change my question, I have a NAT (FW) and my main exchange server is connected to internet via this NAT,

I want use POP3Connector to retrieve mails from my exchange server, when I'm in out of my office.

But NAT doesn't send pop3 request to my exchange server, I check it by sniffer,

when i telnet to my exchange server on port 110 or 25: telnet nebrasweb.com 110 (for pop) or telnet nebrasweb.com 25 (for smtp)

packets goning to the NAT, but they refused to go to exchange server.

but when I send mail via gmail , ... NAT allows the packet transfer to exchange server (because IP Sniffer in exchange server machin shows them).

What is differ in my method(using telnet on port 25 or 110) and gmail or other mail services?

Thanks.

It looks like your firewall my be doing some masking or filtering of the POP3/SMTP traffic. What sort of firewall are you using?

 Can you disable those features? The reason that firewalls are setup to do this is so that people can't send invalid SMTP or POP3 verbs to cause a failure on the server.

It could also be that you are running an antivirus/software firewall on your PC that is blocking that traffic outbound. If you are running Symantec or McAffee personal firewall, see if they are blocking the traffic.

1. In exchange server computer I have Symantec Antivirus Client,

2. I have a NAT server that routes message from internet to exchange server machin,

port 110 and 25's incoming and outcoming maping is as 110, 25,

I can't find any restriction on Semantic anti virus for incoming oucoming ports.

It is possible to send mail from Gmail or Yahoo to my server but when i try to telnet i get on error:

could not open connection to the host on port ... : connect failed.

In all ports I recieve this problem.

but i can ping to server.

my server is: nebrasweb.com or 82.99.225.166 you can check it for telnet and ping, what are defference except port numbers

my official mail is amiri@nebrasweb.com it works fine.

Thanks

From the local network can you telnet to port 25 and port 110 and get a response from the server?
