Install pop3 server 2003

For more information about these cmdlets, see Start-Service and Set-Service. To verify that you've successfully started the POP3 services, use either of the following procedures:. On the Exchange server, open Windows Task Manager. FQDN used for encryption : mail. For detailed syntax and parameter information, see Set-PopSettings. Although you can use a separate certificate for POP3, we recommend that you use the same certificate as the other Exchange IIS HTTP services, which is likely a wildcard certificate or a subject alternative name SAN certificate from a commercial certification authority that's automatically trusted by all clients.

For more information, see Certificate requirements for Exchange services. You don't need to assign a wildcard certificate to the Exchange POP service. For more information, see Assign certificates to Exchange Server services. To verify that you've successfully configured the POP3 settings for external clients, run the following command in the Exchange Management Shell and verify the settings:.

For more information about this cmdlet, see Restart-Service. To verify that you have enabled and configured POP3 on the Exchange server, perform the following procedures:. Internal clients : Use the Test-PopConnectivity cmdlet.

Side note about the "Cost" entry: If you want to send emails to some domains via a different route you can create multiple SMTP connectors and set the "Cost" entry of this wildcard connector to a higher value while setting the cost entry of the special domain route to a lower cost but with only the special domain allowed on this page.

This can be used if you generally want to send via DNS and only route to some systems that won't accept your email via some relay server. This allows your to instruct our Exchange server to use a different e-mail server smart host to send e-mails depending on the domain you send to. Unfortunately this is seldom useful and does not allow different smart hosts depending on the sender domain.

If you want that please check out our MultiSendcon, the multi-domain send connector for Exchange. Select "Outbound Security":. And that's already it - Your Exchange is now configured to send email to the internet and receive an SMTP email feed like it will come from POPcon or a direct internet connection.

All you should do now is configure your users' email addresses in the Active directory. You can set one or multiple email addresses for each user to receive email at. We will step through the necessary actions when creating a new user called John Galt. The resulting dialog will allow you to create a new AD user to log into your server and creates an Exchange mailbox all in one wizard pass:. Now the wizard continues into the Exchange Server realm and lets us create a new exchange mailbox.

Ok, fine - but wait: What about our desired email address? We need to add this mail address manually. We are back at the AD configuration console and select the properties of our new user "John Galt" by right-clicking on the name:.

And surprise: john servolutions. Actually, Exchange automatically entered this additional email address because we chose so during the editing of the default recipient policies. But we want this address to be the primary address meaning all email sent by John will get this address as the "senders" and "reply" addresses in the mail headers.

So we click on "Set As Primary" and are done:. We could also add more email addresses like info servolutions. And that's really it - just step through your other user's AD entries and set the appropriate primary and additional email addresses. After going through the above 4 steps your Exchange is configured to send out email but it still can't pull down email from POP3 or IMAP mailboxes on your provider server.

For this you need to install and configure POPcon. On this first configuration page you only need to enter the email address of your Postmaster or Administrator user. The Postmaster will receive all emails without a valid recipient as well as general POPcon status notifications. It is very important to define a real email address from inside your exchange server here because mails can be lost irretrievably if POPcon forwards some mail with no recipient information to the postmaster and that account does not exist in your exchange server.

For each server or account you need to fill in the POP3 server settings as shown below. If you are using catch-all style mailboxes mailboxes that receive email for a whole domain, regardless of the recipient part before the " " POPcon needs to filter recipients from incoming mail so only the recipients at your own internet domain are accepted.

Please add the domain you consider your own in the "Accepted Recipient Domains" box. This is the same domain you configured earlier in the Exchange Default Policy. POP3: Default. Remember that the mailbox name must be less then 21 characters 64 for Encrypted Password File and Active Directory. Periods are allowed to use, but not as the first or last character. So, we have now two users. Are they equally? No, bob is a member of the POP3 Users group, which is denied to logon locally.

Ariel is not member of this group, and can still logon locally and access her mailbox. Actually, that's it! It is this simple to configure the POP3 part. But it is not yet working as we want, we have to configure the SMTP part to be able to receive and send emails. Yes, I said receive emails. A common mistake is to think that the POP3 server receives the emails.

But that is not true, all the POP3 is doing is 'pop' the emails out to the clients. First of all, Authentication and Relay is not the same thing.

We use the Authentication button to specify which authentications methods are allowed for users and other SMTP servers. So enabling Anonymous here is not a security issue, in fact, it's required if we want our server to be able to receive emails from other servers on Internet I doubt you want to tell all administrators of email servers on Internet how they should logon to yours.

We also need Windows Authentication so the email clients can authenticate to the server and be able to relay send emails. As Relay Restrictions we selected Only the list below because we do not want to be used by spammers to send emails. But we never specified any computers. That is valid, because we wants our clients to always use the username and password to authenticate, no matter where they are. If you want users to only be allowed to relay if they are on a private network, then you can uncheck Windows Authentication as allowed authentication method, and specify the IP range for your network in the Relay Restrictions window.

Is that all? Do we have a working email server now? Well, the answer is yes. But we still haven't configured the email clients. Are we finished now? Well, let us try to send an email. Didn't work, did it? I'm sure you got an error message similar to this one:. The message could not be sent because one of the recipients was rejected by the server.

The rejected e-mail address was 'webmaster ilopia. Subject 'Test', Account: 'ilopia. The reason why we got this is written in the error message. This means that we didn't get authenticated to the SMTP server. So, let us take a look at the email client's settings again. And hopefully you will receive an email within some minutes if you sent it to your own email account.
