16.6.13 An e-mail cannot be received.
The following table lists how to troubleshoot the problem when an E71 cannot receive an e-mail.
Check item Action
Was the MRECV instruction executed? Correct the execution conditions of the MSEND instruction.
Was the MRECV instruction completed normally?
Check the error code in the MRECV instruction completion status area and
correct the error.
Does the receive data exist in the device?
• Shorten the inquiry interval.
• Check if there is any error in the communication path.
• Check the number of e-mails remaining on the mail server.
Is the receive data value incorrect? (Are the characters in the
subject garbled?)
• Check and correct the e-mail parameter settings.
• Check if the mail server system is down.
• Check if there is any error in the communication path.
Is a device other than the E71 sending the data?
If EUC or SHIFT-JIS is used, perform the following:
• Send an e-mail from a personal computer to the own station.
• Check the header information of the received e-mail sent by the own
station.
For Outlook Express, select "Properties" "Details". In the header
information, check that the setting is "Content-Type:text-plain:charset=iso-
2022jp". If it is "charset=EUC-jp" or "charset=SHIFT-JIS", correct it.
Is the E71 sending the data?
Because the E71 does not decode received data, it cannot receive an e-
mail normally. Try to send an e-mail from a device other than the E71.
Did the sending device send the e-mail in the ASCII code or
convert the ASCII code further into the ASCII code?
Check the following.
• Convert the e-mail attachment into the binary code and send it.
• Check if the sent data (e-mail attachment) is not in the ASCII code.
• When the destination is a personal computer, use another mailer. If the
received e-mails differ depending on the mailer used, check the mailer
settings.
• Check if the encoding and decoding methods of the mail server differs
from those of Ethernet.
