  Using Mailboxes? 
 The Question is:
 
I have a system running under VMS wich uses the
mailboxes to exchange data between processes.
 
If I use a software to read the mailbox being a
user of the same group as all the pprocesses,
there is no problem, but if i try to use the
same software being another user of a different
group, I have an error when initializating the
mailboxes.
 
I think it may be a problem of the software
that is running, or a problem of having access
to mailboxes of another group.
 
The question is:
Do you know if there is a restriction of reading
mailboxes when read by a software that is using
a user from a diferent group ?
 
Thank you.
 
 The Answer is:
 
  When asking questions, please remember to include the specific and full
  text of the error message(s) received -- there are many potential error
  messages on OpenVMS, providing the specific message seen can point the
  Wizard to the actual error condition.
 
  There are two potential (likely) considerations here, the first being
  the device protection mask assigned to the mailbox (you will want to
  allow group or more likely world access, or you will want to add an ACL
  on the device) and the second being the location of the logical name
  table used to contain the logical names that allow the mailbox names to
  be translated into the mailbox MBAn: device names (LNM$PERMANENT_MAILBOX
  for permanent mailboxes, LNM$TEMPORARY_MAILBOX for temporary mailboxes).
