Hello I am training myself as i am sick of being helpdesk. I have installed exchange 2007 to my domain member server in vmware workstation. I am able to send and receive mails internally but not able to send or receive mails from outside. I m using a laptop that is getting wireless routers assigned ip and ll my servers are created on vmware workstation. SERVER DETAILS: domain controller: Uses vmware workstation nat static ip: IP:192.168.150.XXX subnet:255.255.255.0 gateway and dns:192.168.150.2 domain:XX.local The domain controller works as dc,dns and dhcp server Exchange server: Uses vmware workstation nat static ip:192.168.150.XXX subnet:255.255.255.0 gateway: dc's ip DNS: 192.168.150.2 I have configured send connector and added rights to anonymous user to default receive connector with steps on http://msexchangeteam.com/archive/2006/11/17/431555.aspx but i noticed that i do not have same colums as on the fourth screenshot(send connectors properties>>address space)..the screenshot has domain and type colums but i have type, address and cost. Dont think this explains my send and receive probelms but just wanted to mention about it

Is Port 25 open and configured to NAT on your Router to your Exchange Server? Confirm with Telnet test outside of you LAN, http://support.microsoft.com/kb/153119MVP Exchange Server

well i tested from my laptop and it telnet works.

Let's split the two functions up as they are not dependant on each other (sending and receiving). For receiving, please follow the below link step by step. Did you create your external MX records and allow them to propagate? Did you create the authoritative accepted domain? For the Send connector, your address space should be * and it doesn't matter about the cost. Please follow the below link step by step: http://technet.microsoft.com/en-us/library/bb738138(EXCHG.80).aspx You can test your DNS and MX records by going to http://mxtoolbox.com/ More info: http://technet.microsoft.com/en-us/library/aa998662(EXCHG.80).aspx Do you have emails getting stuck in any queues? You can check by going to the EMC -> Toolbox -> Queue Viewer. If so, list the errors. Tim Harrington - Catapult Systems - http://HowDoUC.blogspot.com

i have created send connector with address psace of *, I m not so familiar with MX records but i have created new mail exchanger(MX) in DNS by browsing my exchange host a record

Just to clarify....the MX record is for External DNS. Did you follow the links that I provided? http://technet.microsoft.com/en-us/library/bb738138(EXCHG.80).aspx More info on MX records: http://www.arrowmail.co.uk/info/mxrecord.aspx http://aplawrence.com/Unixart/understanding_mx.htmlTim Harrington - Catapult Systems - http://HowDoUC.blogspot.com

External DNS? i only create new MX record to my DNS server, how do i create external? and yes i followed the instructions, except for setting antimspam thingy.

Who host your External DNS records for your external namespace (myemaildomain.com)? this is where you would create A or MX records, for example for publishing OWA, you would need an A record for webmail.myemaildomain.com that points to a public IP address that is associated with your firewall. Sometime organizations host their own external DNS servers, but most of the time the ISP does or the domain reistrar does. You can do an NS lookup for your external domain at the MXToolbox site that I listed. That will tell you what server is authoratative for your domain. This is where you need to create your external MX records.Tim Harrington - Catapult Systems - http://HowDoUC.blogspot.com

haha, i am starting to feel stupid..i think my ISP host my external dns...so what information do i need to provide them to do what?

Hi You can check it from http://www.mxtoolbox.com/DNSLookup.aspx Type in your domain and do a "nslookup" from the page Then you will see where your public dns is hostedJonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

ok...what do i do with this info?

Did it answer if the ISP hosts your public dns zone? If yes, you will have to contact the the ISP and provide them with some dns record name, like... or maybe a MX records for being able to receive mails mail.domain.com owa.domain.com and what IP they should point it to Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

So.. for example i have created domain @test.com...should i call my ISP to set mx record for it?

Depends on who handles your External DNS Records, most likely your ISP. Please follow the first part of this article that explains what you will need to do. http://www.msexchange.org/tutorials/MF002.htmlMVP Exchange Server

You don??t need an mx for your domain to send mails out. You need mx only to receive emails. Yes, contact your ISP and make sure that the mx are correctly configured. Was this working before? Do you receive an NDR when you send mail out?

This is my first time setting exchange, so it has never worked and i do not receive ndr unless i force the ndr from mail queue and i m running exchange 2007. I think i have to contact my ISP about the mx thingy and i also think that port 25 might be blocked my them..

Try setting up send and receive connectors on both Edge and Hub in Exchange 2007.
