Hi everyone, I have a problem configuring an exchange server on SBS2003. I have managed to sent email, but here is my problem I can not receive email. I know litle about echange. I know that my connector is setup allright because I can sent email, I have enabled the policy(if you install SBS it wil be enabled by default). I have configured a smart host wich i believe is the (yourdomain). in system manager in mailboxes I can see the Items is groing but I don`t see mail in the inbox. can you please tell me what to do step by step how to be able to receive email . thanxs in advance

Thanks. We'll let you know when a new response is added.

What do you meen by “ask them to add a sub-domain to your existing domain.” while i have mx record created. I have a <domain.com> in there I have created a subdomein <mail.domain.com> which also is my mx record. if i nslookup that mx record it returns my external ip address. and configured as smart host. is this ok?

other question:
If i go to system manager -> servers-> <servername>-first storage group-> mailbox store-> mailboxes, I can see the user mailbox size and Total Items increasing but the user don`t get the messages in Outlook or OWA.

====================
Please post the second question separate from this one. Please also post your feedback in the discussion section below so as not to clutter this section.

It sounds like your MX record is incorrect. The MX record must point to an A or CNAME record for a host that is capable of receiving inbound port 25 connections for SMTP. For example a few of the yahoo.com MX nslookup records look like this:

<i>yahoo.com MX preference = 1, mail exchanger = c.mx.mail.yahoo.com
yahoo.com MX preference = 1, mail exchanger = d.mx.mail.yahoo.com
yahoo.com MX preference = 1, mail exchanger = e.mx.mail.yahoo.com
c.mx.mail.yahoo.com internet address = 216.39.53.3
d.mx.mail.yahoo.com internet address = 66.196.82.7
e.mx.mail.yahoo.com internet address = 216.39.53.1</i>

The host that is specified in the A record referenced by the MX record must be accepting connections on port 25 on a public IP address to be able to accept email for your domain. If the firewall is not open for port 25 or the host does not have a public IP address, then there will be no inbound messages delivered to your domain.
======================================

the router is configured to forward port 25 internal and external.
The MX record I created is on the host side not server side, on SBS 2003 side(sorry for not mentioned earlier) <b>I used CEICW. there I used the ISP as smtp and on the next page I used the MX record which I believe is the smart host.</b> after that domain.com and this should work but nothing I can send email but not receiving any mail. a lot of webhosting gif the possibility to setup your own DNS, MX or what so ever.
I still hope you can help me out.
========================================
Beside the MX record I need to know if I configured the server right in order to learn from the mistakes.

Like I mentioned above.

after configuring the router for p25:

1. contact ISP to forward/create mx for the external IP
2. Using CEICW
3. ISP domain for SMTP
4. <yourmx.com> as smart host
5. <domain.com> for email domain

6. after wizard: default recipient policy whill be created for domain.com.
7. email sent and receive.

Is this the right way or is my terminologie completely wrong. if so can you participate where needed.

thanx i.a

    To recieve emails to your Exchange server, the internet DNS servers need to know where your exchange server is located. You need to contact your ISP and setup a DNS Mail eXchanger (MX) record. The MX record in DNS is used to indicate which server is used to handle emails for you domain. I have setup an MX record but I can not seem to test the mx record when i use telnet <domain> 25 i get error "can not connect". I now I have to wait for a view hours for the MX to get updated but still.. nothing I thingk I did somthing wron in the configuration can you give me a step by step on how to set this up pls Basically, Exchange can handle hundreds of mail domains without any problem (up to about 1000 domains), so performance is usually not an issue. In all of the above examples you'll need to configure Exchange to use new (or modified) Recipient Policies to reflect the change in the e-mail domain names. Note: You can also configure only a specific range of recipients to receive the new e-mail address. That topic is covered in the Configure Specific E-Mail Addresses for Specific Exchange 2000/2003 Users article. In order to create a new Recipient Policy please perform the following steps: 1. Open the Exchange System Manager. 2. Navigate to the Recipients folder, expand it and go to Recipient Policies. Right-click Default Recipient Policies and choose Properties. Note: You can also create new Recipient Policies instead on modifying the Default Recipient Policy. You will want to do that in cases when you want to choose specific users or recipients on whom you'd like the new policy to apply. That topic is covered in the Configure Specific E-Mail Addresses for Specific Exchange 2000/2003 Users article. 3. Click on the E-Mail Address Policy tab. Notice how the default SMTP E-Mail address suffix is exactly the same as your AD Domain. This is where we want to add the new domain. 4. On the E-Mail Address Policy tab you can add all sorts of e-mail addresses, but the most common one is SMTP of course. Click New, choose SMTP and then configure your Internet E-Mail Domain name (the one you plan to add to all your Exchange recipients - users, groups, contacts and Public Folders). Remember to add a "@" sign before the new domain name. You can also select the new e-mail address to be the primary address (i.e. in bold, and it will be used as the e-mail address to where the replies to messages sent by your users will be sent). Make sure you place a V in the checkbox near the new domain name, otherwise this policy will not make any changes to your recipients. Note: You can add as many e-mail domain names you want (you should of course OWN them...duh) and the policy will configure them all. Lamer Note: No, entering "kuku.co.il" is not what YOU'RE supposed to do, this is just an example. You need to BUY your OWN domain name and then have it configured to send e-mail traffic to YOUR server. Read the Configure MX Records for Incoming SMTP E-Mail Traffic article for more info on this topic. When you're done click Ok. 5. Read the Exchange System Manager message that pops out and click Ok. Basically, this message tells you that if you plan to make changes to this filter you should then run the Apply Policy Now option. 6. After you've set your policy, you will now need to apply it. Right-click it and select Apply this Policy Now. 7. In order to make things happen faster, you'll want to re-run the Recipient Update Service - or RUS - (both of them in most cases, all of them in case you have more than one AD domain). Go to the Recipient Update Service folder and in the right pane right-click all the instances of the RUS you see, and select Update Now. 8. In order to test the success of the new Recipient Policy, go to one of your recipients and see if the new e-mail address is listed in the recipient's properties. Done! In cases where the new e-mail address we've just configured is a sub-domain of your current existing domain you'll need to contact your ISP or Name Server provider and ask them to add a sub-domain to your existing domain. In cases where the new address is for a totally different domain you'll need to configure the MX Records for the new domain. Without performing this step no one will ever know that your server is in fact serving this new domain. Read my Configure MX Records for Incoming SMTP E-Mail Traffic article for more info on this subject. You can also test to see if your Exchange server is in fact willing to accept messages destined for this new domain. ------------------------------------------------------------------ What do you meen by "ask them to add a sub-domain to your existing domain." while i have mx record created.

    You must setup a PUBLIC DNS record of the MX type. Try the MXtoolbox.com website and see if your MX record can be resolved by another server on the public internet. Until that is resolved inbound mail will fail. Another thing that will cause inbound mail to fail is that port 25 is not listening on a public IP address. Try to telnet your.public.ip.address 25 from outside of your network. If that is not working then inbound mail flow will fail. Please don't repost the entire content of the discussion or answer. This thread is getting difficult to read.
