When E-mail sending logs are recorded, Systemwalker Desktop Keeper monitors the SMTP port (the port number specified during the installation of client (CT)). In other words, the E-mail software that uses SMTP communication protocol during E-mail sending will be monitored. When multiple E-mail software is being used, set each SMTP port number to the same one.
The Web mail and groupware that do not use SMTP communication protocol cannot be monitored. However, when you send email from Microsoft(R) Outlook(R) 2007 or a later version of Outlook, email sending logs are collected even if the protocol is not SMTP (no logs are recorded for sending of items other than emails, such as those by the Microsoft(R) Outlook(R) Text Messaging feature (SMS) and FAX sending feature).
When Microsoft(R) Outlook(R) 2003 or an earlier version of Outlook is being used and the type of server that uses Outlook E-mail account is "Microsoft Exchange Server", since it is not SMTP protocol, E-mail sending logs cannot be collected.
If the port number specified during installation has been disabled by personal firewall, E-mail sending logs cannot be collected.
The E-mails to be sent must be encoded with JIS:ISO-2022-JP, UTF-7, UTF-8, or US-ASCII. The E-mails not encoded with JIS:ISO-2022-JP, UTF-7, UTF-8, or US-ASCII will not be sent. Even the policy of collecting E-mail sending log has been set, the logs will not be collected.
However, these restrictions do not apply when you send emails from Microsoft(R) Outlook(R) 2007 or a later version of Outlook.
When Microsoft(R) Outlook(R) 2003 is used to send an E-mail that contains Unicode characters and Auto select encoding for E-mail sending has been set, even the characters are set to Japanese (JIS), they will be replaced with Simplified Chinese (GB2312) before sending the E-mail. Therefore, do not set Auto select encoding for E-mail sending in Microsoft(R) Outlook(R) 2003.
However, these restrictions do not apply when you send emails from Microsoft(R) Outlook(R) 2007 or a later version of Outlook.
If the E-mail software does not comply with the "RFC2183" standard, the logs cannot be collected properly sometimes. (For example: attachment name cannot be recorded)
However, these restrictions do not apply when you send emails from Microsoft(R) Outlook(R) 2007 or a later version of Outlook.
The maximum size of all information collected in E-mail sending logs is 2048 halfwidth characters (1024 fullwidth characters). If the information exceeds this size, information items will continue to be deleted in the sequence described below until the size is within 2048 halfwidth characters (1024 fullwidth characters).
Therefore, when part of the E-mail sending log has been deleted, file related to the e-sending log may not be traced in the Log Viewer.
The sender address will be truncated to 100 halfwidth characters (50 fullwidth characters).
The recipient address (Bcc) will be truncated to 500 halfwidth characters (250 fullwidth characters).
The recipient address (Cc) will be truncated to 500 halfwidth characters (250 fullwidth characters).
The recipient address (To) will be truncated to 500 halfwidth characters (250 fullwidth characters).
The E-mail subject will be truncated to 100 halfwidth characters (50 fullwidth characters).
The attachment name will be truncated to 300 halfwidth characters (150 fullwidth characters).
An email address that does not conform to RFC-5321 may be cut off when it is recorded. The same applies to the address portion of the original storage email.
For the recipient address (Bcc), only the address part will be recorded as log. The names attached to the E-mail software will not be collected.
During the installation of a new network device and a LAN driver, the E-mail sending logs will be collected only after the client (CT) has been restarted.
However, when you send emails from Microsoft(R) Outlook(R) 2007 or a later version of Outlook, email sending logs can be collected immediately even if you do not restart the client (CT).
When the recipient addresses (To, Cc, or Bcc) contains "," and ";", based on the difference of E-mail software, addresses are separated at ", " and ";" sometimes before logs are collected.
If the recipient addresses in the To and Bcc fields are the same and the recipient addresses in the cc and Bcc are the same, the recipient addresses in the Bcc field are not logged.
The Systemwalker Desktop Keeper add-on has been added in Microsoft(R) Outlook(R) 2007 and later versions of Outlook. Do not disable or delete this add-on, because doing so will cause Outlook to be terminated by force. If multiple users have logged on to the PC, Outlook may be terminated by force not just for the user who disabled or deleted the add-on but for all users.
If you attach a file with a long name to an email in Microsoft(R) Outlook(R), the name of the attachment may be shortened when it is recorded. For example, when Microsoft(R) Outlook(R) attaches a file, it changes the file name portion (preceding the extension) so that the total number of characters including the extension is 255. Therefore, the maximum length of the file name to be recorded as the email sending log is also 255 characters (regardless of whether the characters are halfwidth or fullwidth). Microsoft(R) Outlook(R) 2013 shortens the names even further and sometimes appends "..." to the file name. When a file name is shortened in this way, the file cannot be traced.
A maximum of 1023 characters (halfwidth and fullwidth) is recorded for each of the following: email attachment prohibition log, email sending log (sent after confirmation), email sending interruption log, warning address (or list of warning addresses if there are multiple applicable warning addresses), and attachment name (or list of attachment names if there are multiple names). Any portion beyond 1023 characters is discarded. In addition, if there are multiple attachments, one email attachment prohibition log is created per attachment. However, if the list of attachments exceeds 1023 characters, no logs will be recorded for the excess attachment names. Moreover, the last file name may be cut off when it is recorded.
If you specify a sender other than the prescribed account when sending email from Microsoft(R) Outlook(R) 2007, the sender recorded in the email sending log is the email address of the prescribed account.
About Viewing E-mail Content
After MIME encoding, the E-mail contents (including body text and attachment) will be saved on the server as a file for viewing. Therefore, the file size is the size of the MIME-encoded file. If the file of E-mail content exceeds 50 MB, the contents cannot be saved. E-mail sending log can be collected.
Since the backup tool will not back up the file of E-mail content, it is recommended to back up the file periodically.
Similar to other backup original files, the file saved on management server for viewing E-mail content cannot be original file backup by the backup tool or command.
When you send emails from Microsoft(R) Outlook(R) 2007 or a later version of Outlook and you store the original email, the file extension when you retrieve the original email from Log Viewer will be msg. Microsoft(R) Outlook(R) must have been installed on the PC before you can view the original emails.
Emails that you send from Microsoft(R) Outlook(R) 2007 or a later version of Outlook and whose original you stored are displayed in draft format.
Email sending log
Unencrypted storage takes effect after it is set on Management Console. Emails that have already been stored remain encrypted. Even if you enable encryption, original emails that were stored without being encrypted remain unencrypted.
