keep messages on server doesn't work?


    Hello to all,

    I'm making some tests on keep mail on server to see how popa3d reacts 
    between new and old messages.

    I use fetchmail to this tests with keep option and when it fetches mail 
    it says "not flushed" but every time that I restart fetchmail, it 
    fetch all the mail again. I assume that it is suposed to only 
    fetch new messages and keep old messages on server.

    Bye,

    		Nuno Teixeira

That's a fetchmail thing and has very little to do with popa3d.
fetchmail uses by default the deprecated LAST command, which is not
supported by popa3d. To make fetchmail only get new mail, add the UIDL
option to your fetchmailrc.

Re: keep messages on server doesn't work?


    Hi,

    Thanks very much for your quick help. I've added UIDL feature to 
    fetchmail and it works fine.

    I'll make some tests with Outlook Express to see if it supports this 
    feature too, and if it will, I'll use popa3d on my server to substitute 
    qpopper.

    I'm reading rfc1939 to understand better this feature.

    Thanks again,

    		Nuno Teixeira

     " Under  POP3, blame RFC1725.  That version of the POP3 protocol specifi-
       cation removed the LAST command, and some POP servers  follow  it  (you
       can verify this by invoking fetchmail -v to the mailserver and watching
       the response to LAST early in the query).  The fetchmail code tries  to
       compensate by using POP3's UID feature, storing the identifiers of mes-
       sages seen in each session until the next  session,  in  the  .fetchids
       file.  But this doesn't track messages seen with other clients, or read
       directly with a mailer on the host but not deleted afterward.  A better
       solution would be to switch to IMAP. "

    

    What shoul I do:

    	- Use UIDL
    	- Switch to IMAP (please no!)

New to popa3d, SMTP-after-POP-patch

Hi,

i'm new to the popa3d dawemon an this list. I just switched from
Qualcoms qpopper to popa3d and want to thank you for this nice peace
of software.

I have added my SMTP-after-POP solution for sendmail, that i used with qpopper
for years, to popa3d, perhaps this is useful for someone... It can be
downloaded from http://www.koblenz-net.de/~horn/smtp_after_pop/

This solution follows a slightly modified approach than others. The pop3 daemon
directly inserts the IP-address of the client into sendmails access.db
database. So you need no sendmail hack or syslog parsers, but, you need a small
program that removes addresses again from access.db. You can find all this at
the address given above.

Comments are welcome,
Georg

Hi,

Please excuse the lack of participation in this discussion on my part.
I am travelling, currently in Brussels where I spoke at FOSDEM
(www.fosdem.org) and I don't always have Internet access during this
trip.

Jakob, -- thanks a lot for your response on this.

I'll add some more detail:

popa3d does have some very limited optional fake support for LAST,
just to not confuse the very few ancient clients which depend on it.
This is a compile-time setting in params.h which you may disable.

Thank you for sharing this with me and others.

I think I'll add this to the contributed patches list (even though it
will be the third alternative popa3d patch to do POP-before-SMTP), but
you may want to correct a few things first:

1. The patch file name.  I generally prefer them to include a patch
version number such that people may see when a patch is updated.
Something like popa3d-0.5.1-smtp_after_pop-1.diff would be better
(I've added the "-1").

Problem when retreiving messages with no body

Hi,

    I have some difficult to write in English. Sorry...

    I have recently installed popa3d on my Slackware server, serving to
approximate 1000 users. In same way that another user related, I can't
retrieve messages with no BODY, like the example above:

.end of previous message .

From expostar@...  Mon Feb 17 15:18:35 2003

Return-Path: <expostar@...>

Received: from miro.imagenet.com.br (IDENT:0 <at> miro.imagenet.com.br

Well, but it's the most elegant one (that is i think so ), as it works
without installing additional software or hacking the sendmail configuration.
At least if the access.db-Feature is already installed...
And it works with the current version of popa3d.

Ok, i uploaded the new patch that also contains your other suggestions
to the address above.

Did you build it from the original source tarball or is this the
Slackware package?

There's a known bug in OE which causes this, popa3d 0.5.9 includes a
workaround so I suggest that you try that version.

Now this is weird.
