- The problem with RFC1339 is that it is very difficult to implement correctly
- on VMS. The protocol returns two pieces of information to the caller -- the
- time when a given user last read a mail message and the time when that
- user last received mail.
-
- On VMS using VMS MAIL both of these numbers are very hard to come by.
- Consider the problem of finding out when mail was last read. I know of
- no way to do this. The revision time on the user's MAIL.MAI file is no
- help, since it is updated by deliveries and in any case is not updated
- until you exit from VMS MAIL! (Some users, such as myself, stay in VMS MAIL
- for weeks or even months at a time. And the revision date gets changed
- to whatever time you exited regardless of when you last read a message.)
-
- The last delivery time is also a problem. Again, the file revision date
- is not a useful source of this information. About the only thing that
- could know when delivery was last done is the delivery agent itself. I suppose
- we could all get together and support a common place for putting this
- information. Of course, local mail would not update this information since
- it only passes through VMS MAIL itself.
-
- There's a limited version of the protocol that is slightly more implementable
- in the VMS environment, but not overly so.
-
- If you can come up with a reasonable way to deal with these issues in the
- VMS environment I'd love to hear about it. I had serious thoughts about
- implementing this protocol in PMDF until I started to consider how the
- actual implementation would have to be done.
