Qpopper Monthly Help File

         M O N T H L Y   Q P O P P E R   L I S T   H E L P

This is a routine monthly reminder of how to unsubscribe or use other
list commands.

First off, when you subscribe to a mailing list, you almost always get
a first message from the list admin telling you about the mailing list,
and explaining how to unsubscribe.  It is always a good idea to keep
these messages, since you never know when you will need to unsubscribe.
This is particularly useful when you change email addresses, because it
is difficult to unsubscribe from a list after you have a different
mailing address.

Every message sent by the list includes headers that you can just click
on to subscribe, unsubscribe, get help, or see the archives (if the
list has archives).

If you have tried this method, and the mailing list software won't let
you unsubscribe, it is probably because your address has changed.  In 
this case, please send a message to 
<mailto:listmaster <at> lists.pensive.org> stating which list (or lists) 
you want to unsubscribe from, and what you think your previous address
was.  There is a human (me) who will then try to take care of your 
request, often within a few days.

The list server in use (called AutoShare), offers several options which
you can set for yourself.  These options affect how the list sends you
messages.

The available options are:

Re: weird problem after upgrading to qpopper

Hi all
I am replying to this as I have a similar problem that I have been trying to 
track for a while now.
Suddenly(about 10 days ago) I start getting mail in from a couple of months 
ago.
It is rather embarrasing as it was an invite to customers and some of them are 
mad because they wanted to partake in the special.
I checked the headers and mailman, mailscanner server, and sendmail/procmail  
on the box delivered it on that day.
It also happens randomly and I can not see a specifc pattern. Of the tens of 
thousands that I sent I recon 500 or 600 have problem.
I will be interested to see the headers of the mail that you got in late. 
Check if sendmail delivered it correctly a year ago that way we can see where 
your problem is.
I use redhat 7.3 sendmail 8.12.6 and qpopper  version 4.0.3 (standalone)
The only thing I cannot varify is qpopper.

Tnx

RE: weird problem after upgrading to qpopper

I am running Solaris 8 with Sendmail Switch 2.2(the commercial version
of Sendmail).  I run procmail as the local mailer and am currently
running ipop3d(the version that came with the Sun Internet Mail Server
that was packaged with Solaris 7.)  I tested qpopper 4.0.3 a few months
ago when we began having problems with customers mailboxes locking up
for no reason.  We could simply move the mailbox to a temp file, send a
new test message and have the user check it and delete it, then simply
move the temp mailbox back and then they could download the messages.
Weird.  Anyway, back to the point, once qpopper was installed, customers
began receiving messages that they had already received many months ago.
It's not that the messages were never delivered, it's just that they
appeared again.  That is why I am thinking that the when my users
checked their mail using our webmail server, which just retrieves
messages using pop3, that somehow qpopper saw the messages on the
webmail server as new messages and was somehow downloading them back to
the server.  Even getting the messages that were in the users deleted
items in webmail.  Does that sound possible?  I didn't think that pop3
could do anything like that though.

I am going to do some testing on a second server I have available and
see what happens.  I will update everyone once my testing is done.

Hint : perhaps the new style (> Qpopper 3.0) UIDL lines caused
the clients to see already-downloaded messages as 'new'.

Re: weird problem after upgrading to qpopper

Guys,

This is a not unusual problem with pop clients and servers - certainly
not a qpopper problem.
You will find that all those problematic mailboxes actually did have
messages left in them - qpopper did not somehow place mail in them
nor did it find them elsewhere and deliver them to the pop client.
At some stage those users left mail on the server and their client
from then on did not recognise them as new messages so continued to
leave them there.
The users who do not have a problem simply did not leave any messages
on the server.

Someone more cluey than me will be able to explain exactly the
mechanics of uidl but I do know that it is somehow related to the
mailbox itself and the pop server.
When you do something - like change to a different pop server or move
the mailboxes that somehow triggers the server to tell the client that
those messages are new - so they get downloaded. If they continue to get
downloaded then it probably means that the message is not being deleted
from the server - almost certainly a problem with the pop client...

I hope this helps a bit...

Regards, Peter

I'm not familiar with ipop3d, but I suspect the problem is caused by
different UIDL schemes used by ipop3d and qpopper.  If so, your users'
POP3 clients saw everything as new mail, so downloaded it all over again.

That raises the issue of why your POP3 users' mailboxes still contained
mail many months old.  Do you allow them to leave mail on server even
after their POP3 clients have downloaded it?

POP3 uploads mail from the server to client (your webmail is a POP3
client).  It isn't possible for POP3 to move mail from client to server.

RE: weird problem after upgrading to qpopper

I figured it was something with the pop client.  The webmail system we
have in place is nothing more than a pop client.  I believe that the
uidl is going to be the problem.

UIDL issues with QPopper?

Possibly related to an earlier thread, ANY time I recompile QPopper, even
with the same options, all stored mail gets redownloaded.  I personally
store messages on the server for up to 5 days so I have access to it via my
webmail, and several of my users (mostly family) leave messages on the
machine as well because they use the webmail exclusively (although that end
is processed by UW-IMAP.)

In any case, have I missed this as a documented behavior, or is there
something rotten in Denmark?  This is consistent on several machines that I
admin.  This behavior was also present before the use of an IMAP daemon.

That's, well, interesting. It shouldn't happen. Have you tried doing a 
UIDL list of msgs, recompile qpopper, do another UIDL list of msgs and 
compare the UIDLs. (telnet to 110, USER username, PASS password, then 
just UIDL to list UIDLs) (I don't know how knowledgable you are in POP3 
commands). The lists should match.

To allow proper interaction with the webmail solution we use, we have 
qpopper compute UIDL on the fly, rather than store in the mailbox. We find 
this works MUCH better. Might be worth trying.
