SYMPTOMS
Microsoft Mail Gateway to SMTP displays the error messages:
 * Error SMTPGET: 20 - Insufficient memory -or-


 * Error SMTPPUT: 20 - Insufficient memory



CAUSE
The causes of this error message are many. Follow the steps listed below to troubleshoot the error.



WORKAROUND
Verify that the following conditions are met to ensure proper operation of the SMTP gateway:
 * 1) The gateway computer must have at least 375 KB of free conventional memory before starting.
 * 2) The gateway must have at least 40 KB of free contiguous memory, (in the Idling line after the word "largest").
 * 3) The Smtpgate.exe file must be located on the gateway computer, not on the server.
 * 4) Delete a zero length From_NC.api file from the M:\SMTP subdirectory.
 * 5) If P1 files are found in the P1 subdirectory on the postoffice, run the external program to deliver the messages.
 * 6) Have at least one instance of the external program running.
 * 7) It is recommended that the gateway include the -MD parameter on the command line. This will prevent the gateway from performing the Mailer function.
 * 8) Check Network.glb and key/mbg pair for corruption. Check XTN files for zero byte files.
 * 9) The FILES= entry in the Config.sys file should be set to at least 40.
 * 10) Return the last message in the queue, as it could be corrupted.
