clarication of pop3

First off. I've never used POP3 daemons. There may be need
for a custom 
setup now. Got a few questions.

Is it, and where, recorded when a message has been
downloaded by the 
POP3 client (any number of times). I'd guess the
dbmail_messages status 
column?

The option for POP3 "leave messages on server",
is purely client 
specific? Can I make dbmail-pop3d force deletion when the
message has 
been downloaded?


Thanks,
	Alex

AFAIK leaving messages on the server is a client thing. And
IMHO is bad.
My experience sofar with pop3 leaving messages on the server
is that at
the end you still get messages double or more often.
Furthermore pop3
at most ISP has mailbox limitation in size. Leaving the
messages on the
server would soon leave you with a full mailbox.

If you need messages stored on the server, please try imap.
You'll like
it.

I know. I'm asking if there's a way to
"override" the client option 
"leave messages on server". Which is really to
delete it, if the client 
didn't.

Know if there's an entry in dbmail tables, when a message
has been 
downloaded?

The real problem with this, as those of us who still service
dialup
customers know, is how does the server _really_ know that
the entire
message was downloaded?  I suppose one could trigger off of
the proper
'quit' command, but on occasion I see a client break that
as well...

  That's true for imap as well.  In fact, it's probably
worse
with imap, as you can store messages in other folders, and
even
set up your Sent folder to be stored in imap.

  The message status is changed.  From memory, status = 0 is
unread,
status = 1 is read, status = 2 is deleted.  All you'd need
to do is
update all status = 1 to be 2, and run dbmail-util to clean
the rest
up.  I think in 2.0 and later you also need to update the
users'
quota usage, too (in 1.2, which we're using, usage is
calculated
dynamically).  If you need help determining *exactly* what
to do,
try changing pop3d's log level to 5, check and delete a
message
with pop3, and you can see exactly what queries are run.

Sorry, misread/interpreted.

I know cucipop has implemented this feat. It has an daemon
option to
force mail deletion.

Thanks, thing was I only have used dbmail for IMAP. That's
why asked 
about the status for pop3d. Thanks alot.

This also means I can do a periodic set status=2 where
status=1, to 
force deletion. Or even better, cause it's a custom setup,
I could 
change dbmail to set status to 2 instead of 1, when a
message has been 
downloaded.


Thanks a bunch everybody,
