2.1.8 i-Fax Divided Data Transmission
The mail division mechanism (message/partial) as prescribed by RFC2045 is used to divide mail data for transmission.
If the data of a mail is in excess of the size specified for 'transmission data size upper limit' in user mode, the mail will be transmitted using the specified upper limit.
The order of pages in page-based divided transmission may not be as expected on the receiving side.
A job may make its way between jobs.
In the event of a log mismatch between transmitting and receiving sides, or if the size of the image data per page is in excess of the limit, a solution is offered for
the resulting error.
However, if the communication is by way of a mail server, there will normally be an increase in the mail data size when the server affixes a Received header.
To accommodate the fact, the division is initiated with a safety margin of about 4K bytes at time of transmission.
The transmission is by way of a server, or is a server-less transmission in which IFAX-SZL of service mode is set to '0'.
-the target of transmission is set to 'data size division: ON' in the address book.
-the data size of the transmission mail is in excess of the 'transmission data size upper limit' set in user mode.
-if the transmission is by dividing the data, there will be a serial number affixed to the head of Subject of each mail (e.g., [1/5], [2/5],..., [5/5]).
-mail data will carry 'message/partial' as 'MIME Content Type' to indicate the use of divided transmission.
-there will be indications of 'number', 'total', and 'division ID'.
-'division ID' is a character string made up of the following: date of transmission, time of transmission, 0000 (fixed character string), transmission file number, host
name.
-all units of the same mail will have the same ID'.
ex:
Content-Type: message/partial; number=1; total=3;
id="20041110104508.0000.CanonTxNo.0105@e320g-43-1.ccm.canon.co.jp"
2.1.9 E-Mail Divided Data Transmission
If a value other than '0' is set as the 'transmission data size upper limit' in service mode, the size of data sent for a single mail will be no more than the specified limit.
If the transmission data size is in excess of the setting, the following will be true for models other than the iR C3170/C2570:
-if 'data size division' is enabled (ON) for the target in the address book, data size division transmission will be executed; if disabled (OFF), on the other hand, the
transmission will be by page-based division.
-when division transmission is executed, there will be a serial number affixed to the head of Subject of each mail (e.g., [1/5], [2/5], ..., [5/5]).
-if multiple mails have been transmitted to individual addresses by divided transmission, the transmission results report and the communications management re-
ports will treat them as a single mail.
(1)Data Size Division Transmission
If the size of the mail is in excess of the 'transmission data size upper limit' set in user mode as prescribed for mail division (message/partial) in RFC2045 and
RFC2046, the mail will be transmitted using the upper limit.
If the mailer supports RFC, this function enables merging of received mails.
However, if the communication is by way of a mail server, there will normally be an increase in the mail data size when the server affixes a Received header.
To accommodate the fact, the division is initiated with a safety margin of about 4K bytes at time of transmission.
-mail data will carry 'message/partial' as 'MIME Content Type' to indicate the use of divided transmission.
