 Contact the system programmer.

System programmer response
 A possible cause for this error is
that the UNIX file system that
contains the dead letter directory is full or nearly full.  If this
is the cause of the error, perform one of the following:  Determine what can be deleted in the file system and delete it.
Change the DeadLetterDirectory configuration statement to be a
directory on a different file system and issue a MODIFY REFRESH command
to use the new  directory.

 If the problem persists, then either issue a MODIFY
SUSPEND command or change the DeadLetterAction configuration statement
to DELETE.  
 Determine whether you need to issue the MODIFY
SUSPEND command.     
 Issue the MODIFY D,SPOOLSTATUS,SUMMARY command to determine the
number of mail messages that are in the pending or long retry state
for each JES task. From the summary  report, obtain the TKID value
that has pending or long retry mail messages,  then issue the MODIFY
D,SPOOLSTATUS,DETAIL,TKID=tkid command to display
detail  information for the specific JES task. 
If there is a large number of mail messages in long retry, then
there might be a problem with the mail servers. Issue the MODIFY SUSPEND
command to suspend new JES spool file processing until the problem
is resolved. If messages EZD1817I, EZD1818I or EZD1819I are in the
log, they might help in  determining the problem. See EZD1817I, EZD1818I, or EZD1819I for more information.
Delete all unneeded dead letters to free some space in the z/OS UNIX file
system dead letter directory.
