-bash :nmap:command not found
RequestedDeletion and Janet have already correctly mentioned that nmap isn't part of the standard e-smith/SME distribution, but if you're doing it from within your network, it isn't going to produce valid results anyway.  The problem (or at least a problem) is that your firewall is blocking access to the port that's used for email delivery from outside your network (as well as access to pretty much every other port).  You need to fix your firewall configuration.

If you do not know how to do this then you need to get an IT professional to help you.

This is really what needs to be done.

Who is responsible for maintaining your network?  You?  Because if that's your job, and you've got a firewall device that you don't know anything about, you've got bigger problems than your email.  If that isn't your job, then talk to the person whose job it is, and tell them they need to open up the firewall so mail can be delivered to your server.

Your immediate problem is the firewall.  It's blocking access to port 25, which means that incoming mail can't reach your SME server.  I don't think any of us can say whether there may be a problem with the configuration of your SME server as well, but that isn't the immediate problem.  Cisco is a worldwide organization.  I guarantee there is support available for Cisco devices in Saudi Arabia (heck, there's probably support available in Antarctica).  I don't know if you'd be best dealing direct with Cisco, or with a local IT professional.  Or you can remove the firewall entirely and set your SME server to server/gateway mode, in which it will act as the router/firewall itself.  Unless you need some advanced firewall configuration (which seems unlikely, if you don't know anything about the device in the first place), this is probably your best bet.

If you want support for your server, and there aren't SME-knowledgeable IT pros locally, look for one who's familiar with CentOS 6 / Red Hat Enterprise Linux 6.  RedHat's web site (http://redhat.force.com/finder/FindPartner) lists 25 or so vendors in Saudi Arabia; those certainly aren't the only folks who know RHEL, but they would have gone through some training and certification with them, no doubt, and certainly would have paid some sort of fee to be listed.

https://www.theknowledgeacademy.com/sa/courses/linux-distributions-software-training/sme-server-software/dammam/ appear to have a training course in SA on SME Server (it isn't 100% clear that it's the same SME Server, but it sure sounds like it); they may offer support as well.  They were just the second search result when I googled "sme server 9 support saudi arabia"; I have no other knowledge or affiliation with them.

Get rid of it. It is causing you problems, and is unnecessary.

I recall that I already referred you to these people some time ago
From the Koozali partner list at http://www.koozali.org/partners/find-a-partner

Firewall-Services
Technopôle Bordeaux-Montesquieu
33650 Martillac
Aquitaine - France
Tél : +33.5 56 64 15 32
Mail : contact@firewall-services.com
Web : www.firewall-services.com

There is another person in Australia, Graeme Robinson, not sure if he wants to support you in SA, but no technical reason he could not.
He posts here & on bugzilla from time to time, so search & ask.


If agreeable they (Firewall Services) could provide remote support & they know SME server very well.
You are probably better off using someone who understands SME/Koozali server, as other support people may suggest you replace the server with something else, which sort of defeats the intent.

Can you answer the following please:

Why do you need to have a seperate Cisco router in front of your SME server ?
Why do you need or prefer to have SME server in server only mode ?
Is it feasible from a network perspective/reason that you reconfigure the SME to be in server & gateway mode, & reconfigure the physical modem (maybe it's a router) to be in bridged mode (which passes signals straight through with no internal functionality) & you completely remove the Cisco or any other firewall.
That is the simplest & in many cases most effective way of using SME server ie
in server & gateway mode with a modem in bridged mode acting as the connection to the Internet. In this mode, SME server acts as the router & firewall (masq), so no seperate firewall is needed.

Why do you need/prefer to use a corporate DNS server ?
(SME server can do that job quite well on its own) ?

What/why is the reason you have another router ?
(linksys gateway 192.168.1.1 for internet connected with Cisco router each other in switch)
My  guess is that your Internet access for SME server is switching between these firewalls & they are configured differently, one is forwarding ports to SME & one is not, that could be the source of your problem, but I am guessing.

You still have not explained about the domain name (URL), it seems altawi.com.sa is hosted on another server & is providing the web site hosting, & your mail is handled by a different server ie the mserver.altawi.com.sa on a different WAN IP
Why have you split them (if that is correct) ?

Well that is not necessarily correct, something has changed, you are just claiming you made no changes or are not aware of any changes having been made.
Something has changed (eg settings, hardware failure, reconfiguration that someone else did ????)

The sooner you accept that something has changed (ie happened) then you are more likely to start looking at your total system to find what has happened.

You need to explain more fully.

SME server can act as the router for your network, & act as the interface gateway to the Internet, all you need is a modem in bridged mode between SME server & your incoming Internet connection eg ADSL phone line.

Probably your Cisco router could be "dumbed down" & you turn off routing functionality & other functionality eg DHCP etc & set it up purely in bridged modem mode.

You need to answer all questions, just answering one partially does not contribute much to this discussion. Are you lazy ?

What about the second router gateway (firewall ?) why do you need that ?

Draw a detailed diagrammatic layout of your network & show how various devices (SME, routers, Cisco etc) all connect together etc.
Post it back here. This may help us to understand your network.

The short answer to resolve all this is:
Look up the handbook online for your Cisco router & reconfigure it for bridged modem mode (passthrough), turn off ALL other functionality eg DHCP, WAP, dynamic hosting, port forwarding etc etc.
Reconfigure your sme server in server & gateway mode. Enter all the ISP login details & static IP into the admin console, via the "Configure this server" screens.
SME server will do everything your Cisco router has been doing, but with less hassle & it will be easier for you to manage using the SME "server manager".

I cannot do this remotely for you, I don't think anyone can, so you will have to learn how to do this yourself, or pay someone locally who understands how to set up this sort of equipment ie a network technician. They do not need to be an SME server expert.
They can read the SME server Manual online & should be able to work it out if they are technically minded.

...and I now look forward to you following through on your committment "but how if you show me i agree for that and i will do every step you tell me"
Start now.

Are you using a dial-up modem?

You do know that there's a manual, right?  Chapter 5 (http://wiki.contribs.org/SME_Server:Documentation:Administration_Manual:Chapter5) covers installation and configuration.
