The following registry values are also supported. Most, but not all, are for diagnostic purposes. You may need to create these values, for example, to test the integration with Exchange Server before going live:
Available for the Domino server agent only.
Type: REG_SZ
Data: Specifies a list of processes that can host the recovery thread. This list must be a subset of the processes listed in the HostProcesses registry value.
You can use this registry value to prevent a third-party application process from hosting the recovery thread.
Note: If AllowedRecoveryHostProcesses is not present then the entire list in HostProcesses is used instead. There is only one instance of the recovery thread. That is, only the first process to start the recovery thread will actually run it.
Available for the Exchange server and IIS SMTP agents only.
Type: REG_DWORD
Data: Specifies whether to create diagnostic files containing the emails and associated data for emails transiting through the server. These files are:
Contains the ‘raw’ MIME email data for each email processed.
Contains additional data relating to the email, such as the actual recipient list and internal properties.
If this value is set to:
0, the server never creates EML/EMP files.
1, the server always creates EML/EMP files and saves them in the DiagnosticFolder.
2, the server creates EML/EMP files on error and saves them in the DiagnosticFolder.
Important! We strongly recommend that you do not change this setting unless directed to do so by CA Support.
Type: REG_DWORD
Data: Specifies whether an EVF file is created for each email in CA DataMinder EVF format processed by the policy engine hub. If this value is set to:
0, the server never creates EVF files.
1, the server always creates EVF files and saves them in the DiagnosticFolder.
2, the server creates EVF files on error and saves them in the DiagnosticFolder. That is, when an event returns from the policy engine hub with an error. This value is only available for the Exchange 2007 and 2010 server agents.
Type: REG_SZ
Data: Specifies the path and folder where diagnostic files are saved. The creation of these files is determined by the CreateEML and CreateEVF registry values.
Note: This folder is not created automatically.
Available for Exchange and Domino server agents and IIS SMTP agents.
Type: REG_SZ
Data: Defaults to empty, but see ‘Updating an empty list’ below. This registry value specifies a comma-separated list of DNS domains that you want to be considered as a single enterprise. It is typically used with SmtpDNSHostName (see below). Its purpose is to simplify the method for verifying that emails are not reprocessed needlessly by consecutive email server agents.
Note: Values in this list can only contain ASCII characters, without spaces or control characters (for example, tab spaces). Use commas as a list separator.
How does this work? The local email server agent assumes each of the domains listed in EnterpriseDNSList has its own email server agent, and that any email arriving from a listed domain has already been processed by CA DataMinder and does not need reprocessing.
In technical terms, when a remote email server agent processes an email, it writes the DNS domain of the Exchange, Domino or SMTP server to the email’s MIME tag. Or, if the SmtpDNSHostName registry value has been configured, this value is written to the MIME tag instead.
When the local email server agent receives this email, it checks the MIME tag. If the source domain matches a domain in EnterpriseDNSList, the server agent does not reprocess the email.
Updating an empty list: While this list is empty, the DNS domain of the local Exchange, Domino or SMTP server is implied. That is, the local email server agent does not reprocess emails arriving from this domain.
Available for the Exchange 2007 and 2010 server agents and the IIS SMTP agent.
Type: REG_DWORD
Data: Specifies the inter-agent communications port number. Port numbers between 1 and 65535 are valid in this setting. Defaults to 8102.
Note: If this parameter is changed, you must then restart the Exchange server agent or IIS SMTP agent.
Type: REG_SZ
Data: Specifies a text string representing the ‘notification sender’. This text appears in the From: box in all notification emails generated by Exchange or Domino server agents (such as when an email is blocked). For example, you can specify that the From: field in notification emails is always set to ComplianceTeam@unipraxis.com.
This registry value is optional and overrides the default sender (typically ‘postmaster’). The text string must be a valid SMTP address.
Available for the Domino server agent only.
Important! We strongly recommend that any changes to this registry value are made only under the guidance of CA technical staff. For details, contact CA Support at http://ca.com/support.
Type: REG_SZ
Data: This optional registry value specifies a value for the ‘APMState’ item that the Domino server agent waits for before it processes a note.
You can use this registry value to enable the Domino server agent to wait for a third-party application to finish processing, before it applies policy. However, this is normally only used with the HostProcesses registry value.
Note: If this registry value is used, it must be set to the text string that the third-party application sets as the value of the APMState item. For example, 3rdPartyComplete.
Available for Exchange and Domino server agents and IIS SMTP agents.
Type: REG_SZ
Data: Defaults to empty. This value specifies a valid DNS name that complies with RFC naming conventions. It is always used with EnterpriseDNSList (see above). Its purpose is to simplify the method for verifying that emails are not reprocessed needlessly by consecutive email server agents.
How does this work? SmtpDNSHostName specifies a single DNS domain that is written to the email’s MIME tag after it has been processed by the local email server agent. If set, this registry value overrides the DNS domain of the Exchange, Domino or SMTP server in the MIME tag.
To use this registry value as intended, you need to set SmtpDNSHostName to the same value (for example, UNIPRAXIS.COM) for all your email server agents. You can optionally include this value in the EnterpriseDNSList domain list. Now, when any email server agent receives an email tagged as coming from UNIPRAXIS.COM, it knows that policy has already been applied to the email and so does not reprocess it.
