LO78948: Mobile device may send mail more than once with unique IDs.

APAR status

• Closed as program error.

Error description

• Some EAS devices are sending the same mail multiple times.  The
  ClientId is designed to handle this issue, but the devices are
  improperly changing the ClientId each time, so the server is
  correctly saying that it is new and sending it again.  The
  change here is to add an additional check on the server so that
  if the rfc822 is equivalent (ignoring insignificant fields), the
  mail will be considered as already sent and not sent again.
  This will provide an additional saftey to handle devices that
  are not properly using ClientId.
  

Local fix

Problem summary

• This is actually a bug with some devices.  In a mail send
  failure or timeout, the device may resend the mail but with a
  new ID instead of using the same ID as it is supposed to do.
  

Problem conclusion

• The Notes Traveler server has been updated to not only compare
  IDs, but compare mail content to ensure it is not an exact
  duplicate of a mail that was just sent by the device.
  

Temporary fix

• This fix is included in Notes Traveler 9.0.1 IF4 and 9.0.0.1 IF5
  and all future releases.  For the latest Notes Traveler
  maintenance release information please see this technote:
