windows 2003 smtp problem

What do the logs show? Is this a relay or does mail originate on this server and get sent out? Has this server ever worked or is it new? Can you telnet to it on port 25? Does it accept mail and just not forward it or does it not even answer on 25?

I can recive email with pop3 evreywhere . i can send email from my server but i cant send from my pc with outlook express. I get this message :

Send test e-mail message: Outlook cannot connect to your outgoing (SMTP) e-mail server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).

i did contacted my server administration and told them PTR reverse zone for my server and they did it. if you go here(http://www.intodns.com/isolatedserver.com) , you will see that evrey thing works fine.
May be i doing somthing wrong with dns ? but as you see on intodns website all works fine .

Thank you for helping  .

telnet message : Connecting to mail.isolatedserver.com Could not open connection to the host, on port 25: connect failed.

What dose it mean ?

check your smtp connector settings

http://www.msexchange.org/tutorials/Configuring-SMTP-Connector.html

did you tried telnet from internal network?

r from internet ?

which port ur using for smtp 25? 586?

DNS also could be cause of this problem please do a nslookup from exchange server and see dns working properly?

https://www.testexchangeconnectivity.com  try this outbound connection

post the result please

Good Luck

how did you do it ? telnet mail.isolatedserver.com 25 ?

yes

well it has nothing to do to send email from my pc to another pc , right ? let say i send from eddy@isolatedserver,com to you NarendraG@isolatedserver.com , it had nothing to do with blacklist , right ?

yes no problem but i thought u are not able to  receive external mails sorry

black list will cause problem sending emails to external domain defntly not within network

do you have any event errors in exchange server ?

i fixed Out of memory error . i can send email from my server but not from py pc . all test on https://www.testexchangeconnectivity.com/ are good . but still no result from outlookE . :(((((((

Ok let start with your machine again :)


are you able to send mails from any other PC in your network?

nop

i changed the port and it worked , it can be that my isp blocking port 25 ?
