Configuring the SMTP protocol


With the SMTP protocol, HCP can automatically archive emails forwarded by email servers.

SMTP protocol configuration


HCP provides SMTP support for Microsoft® Exchange email servers. For information on which Microsoft Exchange email servers are qualified for use with the SMTP protocol, check the HCP release notes for the version of HCP that you have installed.

You use the SMTP panel to enable and configure the SMTP protocol for a namespace. To display this panel, on the left side of the Protocols page, click on SMTP.

The top of the SMTP panel shows the string to use to identify the namespace when configuring Microsoft Exchange to archive email to the namespace.

The SMTP panel lets you:

Enable the SMTP protocol

Specify the email server IP addresses that have access to the namespace through SMTP

Specify where and in what format email objects are stored

Specify whether to store email attachments separately

The SMTP protocol always stores attachments along with the email they accompany. The HDDS and HCP search facilities and the metadata query engine index the attachments along with the email.

You can choose to additionally store attachments separately from the email they accompany. With this option, searches return not only the original email with the attachments but also the attachments as separate objects.

When attachments are stored only with the email they accompany, searches return only the email objects. You then need to retrieve the email objects and separate the attachments yourself.

Storing attachments as separate objects can have a significant impact on performance and storage space.

Enabling SMTP access to a namespace


The SMTP panel has three sections for enabling and configuring the SMTP protocol.

Settings section

To enable the SMTP protocol, in the Settings section:

1.Select Enable SMTP.

2.Click on Update Settings in the Settings section.

Allow/Deny section

Optionally, in the Allow/Deny section, specify IP addresses of email servers to be allowed or denied access to the namespace through SMTP. For instructions on doing this, see Adding and removing entries in Allow and Deny lists.

For information on how HCP handles IP addresses that appear in both or neither of the Allow and Deny lists, see Allow and Deny list handling.

Emails section

To set options specific to email objects:

1.Click on Emails.

2.In the Emails section:

oIn the Email Location field, type the path for the directory in which you want email objects stored. This is the full path starting after the root directory (that is, rest or data). Be sure to start and end the path with a forward slash
(/), like this:

/email/company_all/

If any part of the specified directory path doesn’t exist, HCP creates it.

For information on the complete path and object names for email added to the namespace through SMTP, see Using a Namespace.

oIn the Format field, select either .eml or .mbox. The one you choose depends on the application you use to read the stored email.

oTo store email attachments separately from the emails they’re attached to, select Separate attachments from parent email. For more information on storing email attachments, see SMTP protocol configuration.

Important: Storing attachments separately from the email they accompany can have a significant impact on performance and storage space. Unless you have a specific reason to do so, do not enable this option.

3.Click on Update Settings in the Emails section.

Configuring Microsoft Exchange for email archiving through SMTP


HCP provides SMTP support for Microsoft Exchange email servers. The following sections outline the procedures for configuring each supported version of Exchange for email archiving through SMTP.

For considerations that apply to configuring Exchange 2003 and 2010 in an environment that uses both versions, see “Exchange 2003 and Exchange 2010 Journaling Interoperability” (http://technet.microsoft.com/en-us/library/aa997918.aspx#Exc).

NoteWebHelp.png

Note: HCP supports archiving email to multiple namespaces. However, with Microsoft Exchange 2003, the recommendation is to archive email to only one namespace.

Configuring Microsoft Exchange 2003


To configure Microsoft Exchange 2003 for archiving emails to an HCP namespace through SMTP:

1.Create a custom SMTP recipient, using a name that’s unique for the namespace. For the recipient email address, use username@namespace-name.tenant-name.hcp-domain-name, where username is the username of any new or existing user (for example, admin@accounts-receivable.finance.hcp.example.com). For the new email address type, select SMTP Address.

For details, see “How to Create a Custom SMTP Recipient for Exchange Server 2003 Journaling” (http://technet.microsoft.com/en-us/library/bb124642%28EXCHG.65%29.aspx).

NoteWebHelp.png

Note: You need to create a separate custom SMTP recipient for each namespace to which you want to archive email.

2.Create journal recipient mailboxes. For details, see “Planning an Exchange Server 2003 Journaling Deployment” (http://technet.microsoft.com/en-us/library/aa998762%28EXCHG.65%29.aspx).

TipWebHelp.png

Tip: For better performance, create the journal recipient mailboxes on separate servers from the user mailbox servers.

3.Define a server-side forwarding rule for the journal recipient mailboxes. For details, see “How to Set a Server-Side Rule for Journal Recipient Mailboxes” (http://technet.microsoft.com/en-us/library/bb124633%28EXCHG.65%29.aspx).

4.Configure Exchange Mailbox Manager to clean out the journal recipient mailboxes after the journalized messages in them are transmitted. For details, see “How to Configure Mailbox Manager to Clean the Journal Recipient Mailbox” (http://technet.microsoft.com/en-us/library/aa995756%28EXCHG.65%29.aspx).

5.Configure the Exchange server SMTP protocol for the target namespace, creating a new virtual SMTP server with a unique IP address. For both the fully qualified domain name and masquerade domain, specify www.namespace-name.tenant-name.hcp-domain-name.

For details, see “How to Configure External DNS Servers on an Outbound SMTP Virtual Server” (http://technet.microsoft.com/en-us/library/bb124221%28EXCHG.65%29.aspx).

6.Configure a dedicated SMTP connector to transmit journalized messages to smtp.hcp-domain-name. For details, see “How to Create an SMTP Connector” (http://technet.microsoft.com/en-us/library/aa996625%28EXCHG.65%29.aspx).

7.For each mailbox store, enable standard journaling. For details, see “How to Enable Standard Journaling” (http://technet.microsoft.com/en-us/library/bb124786%28EXCHG.65%29.aspx).

8.Enable envelope journaling. For details, see “How to Enable Envelope Journaling” (http://technet.microsoft.com/en-us/library/aa997541%28EXCHG.65%29.aspx).

For additional information on this procedure, see “Implementing Exchange 2003 Message Journaling” (http://www.msexchange.org/tutorials/Implementing-Exchange-2003-Message-Journaling.html).

Configuring Microsoft Exchange 2007


To configure Microsoft Exchange 2007 for archiving emails to an HCP namespace through SMTP:

1.Create a custom SMTP recipient, using a name that’s unique for the namespace. For the recipient email address, use username@namespace-name.tenant-name.hcp-domain-name, where username is the username of any new or existing user (for example, admin@accounts-receivable.finance.hcp.example.com).

For details, see “How to Create a New Mail Contact” (http://technet.microsoft.com/en-us/library/aa997220(EXCHG.80).aspx).

NoteWebHelp.png

Note: You need to create a separate custom SMTP recipient for each namespace to which you want to archive email.

2.Create the mailboxes to be journaled. For details, see “How to Create a Mailbox for a New User” (http://technet.microsoft.com/en-us/library/aa998197(EXCHG.80).aspx).

TipWebHelp.png

Tip: For better performance, create the journal mailboxes on separate servers from the user mailbox servers.

3.Create a custom Send connector for the Exchange server. For the address space, use namespace-name.tenant-name.hcp-domain-name. Choose smart host for email routing. For details, see “How to Create a New Send Connector” (http://technet.microsoft.com/en-us/library/aa998814(EXCHG.80).aspx).

NoteWebHelp.png

Note: You need to create a separate custom Send connector for each namespace to which you want to archive email.

4.Modify the custom Send connector for the target namespace. For the fully qualified domain name to be returned in response to the EHLO command, specify namespace-name.tenant-name.hcp-domain-name. For details, see “How to Modify the Configuration of a Send Connector” (http://technet.microsoft.com/en-us/library/aa998836%28EXCHG.80%29.aspx).

5.Create a journal rule to send journal reports to the custom SMTP recipient you created in Configuring Microsoft Exchange 2007 above. For details, see “How to Create a New Journal Rule” (http://technet.microsoft.com/en-us/library/bb124723(EXCHG.80).aspx).

Configuring Microsoft Exchange 2010


To configure Microsoft Exchange 2010 for archiving emails to an HCP namespace through SMTP:

1.Create the user mailboxes to be journaled and, optionally, a new user for each mailbox, using a name that’s unique for the namespace. For the user email address, use username@namespace-name.tenant-name.hcp-domain-name, where username is the username of any new or existing user (for example, admin@accounts-receivable.finance.hcp.example.com).

For details, see “Create a Mailbox” (http://technet.microsoft.com/en-us/library/bb123809.aspx).

2.Create a new SMTP Send connector for the Exchange server. For the address space, use namespace-name.tenant-name.hcp-domain-name. For the smart host authentication settings, select None. For details, see “Create an SMTP Send Connector” (http://technet.microsoft.com/en-us/library/aa997285.aspx).

NoteWebHelp.png

Note: You need to create a separate custom Send connector for each namespace to which you want to archive email.

3.Modify the custom Send connector for the target namespace. For the fully qualified domain name to be returned in response to the EHLO command, specify namespace-name.tenant-name.hcp-domain-name. For details, see “Configure Send Connector Properties” (http://technet.microsoft.com/en-us/library/bb629503.aspx).

4.Optionally, if you have the Enterprise edition of Microsoft Exchange 2010, create a journal rule to selectively journal emails. For details, see “Create a Journal Rule” (http://technet.microsoft.com/en-us/library/aa995915.aspx).
