Also, are you unable to send emails at all ? or just to a few remote domains ?
Looks like something is blocking 25, the best is to telnet and go through the links

Hi Mutahir:
thanks for your comment - I can't telnet to my server port 25 - I now realized that could be the issue but why blocked recently I am confused (it was working great!)
---
is there any alternative ways to fix - go around about this issue?
I am in a hurry to go to work and I shall view all comment posted later tonight!
I appreciated,.
sam
Check your router / firewall ;
Try telneting when you are local to the mailserver (from your lan to your local mail server on port 25)
telnet <mailserver local ip> 25
telnet <mailserver local dns name> 25
If you can connect locally, then you would need to open Port 25 on your router / firewall
From within your LAN ( ON your mailserver's web browser) open the following website :
http://www.canyouseeme.or
this will allow you to see what ports are publicly accessible / visible.
Mutahir:
thanks for your comment & suggestions
I have these telnet result: (from local server lan)

This page will serve as a free utility for remotely verifying a port is open or closed. It will be useful for users who wish to check to see if a server is running or a firewall or ISP is blocking certain ports.
Your IP: xx.xxx.xxx.xx
What Port? 25
Success: I can see your service on (IP Address) on port (25)
Your ISP is not blocking port 25

I am getting the above result on Port 25

Are you using a smart host or DNS records to send mail out ?
Have you tried sending an email to hotmail or gmail or yahoo ? see if that goes through (if you haven't already)
What are your DNS settings :
Step-1
In EMC, expand Server Configuration and click on Hub Transport. Click Properties under Actions. On the External DNS Lookups tab, the default is to use the network card DNS settings. You can specify a list of DNS server to use instead
Step-2 :
Go to, Organization Configuration - Hub Transport and click on Send Connectors tab. open Properties page for your Internet send connector, go to the Network tab and check the box beside "Use the External DNS Lookup settings on the transport server
Check the accepted solution on

Mutahir:
btw,
My router firewall = DISABLED
Port 25 on router is opened (SMTP)

I just go through link:

I am still trying go through with the comment page right now...
I appreciated.,

Mutahir:
I haven't yet consider the smart host option until I try a couple more things including those you've just posted - (now I got more choices)
I can't send mail to both of these domains mentioned - it would rejected ANY email sent from my server

all of the steps has been followed according to your post / comments

what do you want me to post back here - in term of my DNS setting?
thank you for all the timely respond of above posted - comments
I appreciated.,

How long did you have had this exchange server ?
Check your ptr record, if your emails are being rejected by hotmail or gmail or yahoo, then its the ptr (reverese dns) issue
go on mxtoolbox.com and do a check on your server, that will give us more.
it seems to me the PTR issue (reverse dns at your isp) ;
check mxtoolbox and see what comes up on there
I will be able to get back on this after 4pm UK time
Mutahir:
My Server: SBS2008 Standard... (Exchange 2007)

Check the screen shots and verify the settings
after the above steps, you may have to restart the exchange services
http://www.amset.i
You can use the script to restart / start / stop exchange services from the above location (The script is written by Mestha - Exchange Guru)
In your DNS settings try to use 4.2.2.2 and 4.2.2.1 and see if that helps ?
Post back, i am also looking into it further - just got back from work :-0

Above are the steps again which I posted earlier (from the link) ; check your dns settings here ; and specify the 4.2.2.2 dns servers here in this screenshot and restart the exchange services and see if that helps.

At this point, I am not sure any more since I don't know what and where to look for in fix/resolve the issue of sending mail.
I failed but will not stop trying when I get a chance - I will go over again...

please check back with me on my ticket open... if you don't mind
thanks again for your time and effort!
Sam
We can work on this ticket here unless you want to open a new one :
What I am thinking now after reading each and everything again on this page :
a) If there was nothing changed on your side, no router configuration / firewall configuration / internet provider configuration, then it can be :
routing error at your ISP or the recipients ISP
the receiving server is rejecting the message
the receiving server is not alive
the receiving server cannot be connected.
I will post a screenshot (forget the rest) then tell us what dns servers you have in that place, also is there a way you can replace your router for test reasons ? what kind of firewall do you have ?
I think its your router or firewall playing up - just a suggestion - don't make any changes , just let me know which one is it
You don't use any mail gateways ? like message labs or email filtering ?
Mutahir:
for sure I will need to create a new ticket - it's getting very confusing for me and time I've cost for all EE Master!
and you are right on target - a master point of view!
I was in the market shopping for a gateway modem last night (without firewall / wireless feature)
after I found out no more hair to pull from my head...
----
anyway, verison provide whatever in stock - take it or leave it
in sbs2008 - it's firewall enabled since I disabled my modem/router firewall feature
what I didn't understand which I don't want to go back from here... it was working as soon as it was built, setup & deployed... (send/receive)
I can't ssy nothing has changed after I followed all your post/comment (of course, not what we've talked about on "changes")
I am just saying that I made all these changes (according to this closed ticket history) and I think I've come up with these issue: (are you ready?)
I ran "fix my network" from windows sbs console - it report "router" and "smtp" error (CAN'T BE CORRECT?!)
I can't do anything because I need internet - if I plan to replace this modem/remote
I don't understand why it shown remote.servername.com on this server's certificate instead of FQDN?
(all host A & MX records & IP address has been verified with hosting)
if you need a screenshot - I will provide later (don't have word installed on server)
I will open ticket for these subjects in order not to confuses everyone and left my dancing alone!
there's more! but...
thanks for reading - where's my patient?
