You can just
- apply the patch
- 'make'
- copy qmail-pop3d to /var/qmail/bin (you might need to shutdown pop3
  for a second to do so)

qmail-pop3d is the only program affected by this patch.

Greetz, Peter.

Re: Re: doubts about re-compile

[Jose AP Celestino]

Yeah, right Alex.

make
= stop qmail =
cp qmail-pop3d /var/qmail/bin
chown root:qmail /var/qmail/bin/qmail-pop3d
= start qmail =

FIN.

from my experience, the easiest way to effectively kill you

If so why don't you cd the qmail source tree, apply the patch and then:

doubts about re-compile

[J.J.Gallardo]

This is a doubt about the best way to compile again qmail:

I have my system running qmail perfectly, but some days ago i discovered
that qmail has not the patch that "Scott Moorhouse" re-wrote to solve
the problem with the "Netscape's download indicator doesn't progress".
The file involved is "qmail-pop3d.c". I have tried to compile the file
(alone) with the patch apliayed, but may be the file has some
dependencies with another files ( I cannot run  "cc or gcc" over the
file) and so, we have to re-compile all the qmail distribution.

Can I compile "qmail" in another machine and later move and/or copy only
/var/qmail/bin/*?
That's my best option cause only stop the server a minute at the time of
day i wish, but i would like to know others opinions about this.

Thanks.

If you get a connection from inetd/tcpserver you have one FD to read
net input and one FD to write output to the net. These are connected
to 0 and 1 (usually stdin and stdout).
qmail-popup reads from "stdin" (i.e. net-in) a sequence of commands:
USER 
PASS 
or  APOP 
as defined in rfc1939.

It then exec's  "checkpassword"  and provides two additional FDs:
2 and 3. It has to do so, to keep 0 and 1 "unchanged" for read/write to the
network.
FD2 ist identical to FD 1 (ie. write to the network).
On FD 3 it passes USER/PASS/APOP info to checkpassword in the form
   \0\0\0

This is a perl programming problem, not a qmail one.

Check out the section "checkpassword" at http://www.qmail.org/ 
there are examples of perl versions of checkpassword that can be
used as coding examples.

Doubts

[Cleiton L. Siqueira]

Hi all,

I have some doubts about qmail-popup. I read the man of qmail-popup
and
I saw that exist some descriptors used by qmail-popup. My doubts are
about it.
Let me see if I figured out what man page says.
Qmail-popup expects descriptor 0 from the network, sent by a client
like a
Outlook or Messenger. This descriptor 0 has the information about
username
and password. After this qmail-popup writes to the network with
descriptor 1
and calls a subprogram (checkpassword) with the same descriptor 0 and
1.
The
second part of explanation I can't understand. Who uses the the
descriptors 2 and 3?
If qmail-popup uses descriptor 0 and 1 to read and write to network
why
are there descriptors 2 and 3?
What are these descriptors in POP's USER-PASS style?
Where I can find more information about this descriptors?
I need to know this due to I'd like to make my perl program
catching
this
descriptors.
I need to access this descriptor, but I don´t know how I can catch
them.

Thanks in advance.

It reads it from file descriptor 3, as the qmail-popup man page will tell you.

Perl doubts

[Cleiton Luiz Siqueira]

Hi all,
I know this mailing list is about qmail, but I have some doubts about
perl pogram
as checkpassword.
I use this perl program "checkpassword", because I use Postgres Database
to
authenticate my users.
There are somethings into this perl program that I am not able to figure
out.
First:
I start POP3 through inetd using the following line into the inted.conf
file:
pop3 stream tcp nowait root /var/qmail/bin/qmail-popup qmail-popup
mydomain.com
/bin/checkpassword  /var/qmail/bin/qmail-pop3d Maildir
I know that qmail-popup is a responsible program to get username and
password from the
network and after  it gets it  runs a sub-program (checkpassword)
to check username
and password and set the environment variables.
I have three questions about it:
How does qmail-popup get the username and password from the network?
How does qmail-popup send to sub-program (checkpassword) the
informations about username and password?
More specifically what is the format of the data sent to this sub-program
(checkpassword)?
I have the checkpassword program done, but I would like you to help
me about understanding
what the program does. If someone could help about my checkpassword
program I would thank.
This is my checkpassword program:
The most important line that I'd like to figure out is about how it
gets from the qmail-popup the
informations about username and password, how it gets to split this
information and what means
the lines started with $ENV.
If it gets from the standart input, where is it? In the expression
"<&=3"?
If the lines $ENV are to set up the environment variables why must
it do this?
What Do the procedures in bold do?
About the connection with database I don't have any problem.
#!/usr/bin/perl
#
use Pg;
my $TABLE = 'emails';
$conn = PQsetdb('','','','','ab');
%ENV = () ;
my( $len, $buf, ) ;
open( USER, "<&=3" )
  or exit( -3 ) ;
$len = read( USER, $buf, 512 ) ;
close USER ;
exit(-3) if $len < 4 ;
# extract null-terminated user/pass pair from buf
my( $user, $pass ) = split /\x00/, $buf ;
$user = lc $user ;
$buf = "\x00" x $len ;
# Verifying the username and password
$domain = 'ab.com.br';
$result = PQexec($conn,"SELECT * from $TABLE where email= '$user' AND
password = '$pass';");
if (PQntuples($result) > 0) {
if (-e "/home/$domain/$user") {
 
}
else
{
 system("mkdir /home/$domain/\"$user\"");
 system ("/var/qmail/bin/maildirmake /home/$domain/\"$user\"/Maildir");

The qmail-users mechanism allows to add aliases, but it doesn't
prevent delivery to other deliverable addresses. If you want to make
mail to a valid user bounce, set up an assign entry to redirect it to
a ~alias/.qmail-nosuchuser containing:

  |bouncesaying "no such user"

No, there are various "virtual user" solutions available from

some doubts in qmail

[Madhav]

hi,
i have a couple of questions:
1. The following is the assign file i have. here the first field is the mail
address, 2nd user name(linux
 user).
 my problem is i am able to recieve mails sent to both the linux user
and the mailaddress (in my
case [EMAIL PROTECTED] and [EMAIL PROTECTED]). whereas i want to
recieve mails
addressed to madhav only (ie those addressed to mail addresses only).

[root@server1 users]# cat /var/qmail/users/assign
=madhav:msp:510:503:/home/msp:::
=ramkumar:ram:509:503:/home/ram:::
=mail-admin:admin:511:503:/home/admin:::
=sugesstions:cod1:512:504:/coda/qmail/home/cod1:::
[root@server1 users]#

2. my mail clients will be accessing mails only through pop and smtp for
receiving and sending mails. for every mail user is it mandatory to
create a linux user? i actually have about 350 users using mails in
my domain(proposed) that would mean i have to create 350 linux users and in
their home directories i have to create a Maildir. is there any
way by which i can overcome this?

Thanks in advance

No, it does not matter: qmail can run without imapd and vice-versa. They  
can even be on different machines (if the maildir is mounted in some way  
on both).

Get qmailanalog for log analysis. The matchup script will output the
pending deliveries (with the info you require) to fd#5. this makes it
easy to carry it from matchup to matchup (see man matchup).

No, there is only one queue for local and one queue for remote. The
23-way split is just to avoid too many files in one directory (e.g. 200
in each of 23 directories rather than 4600 in one). This is to make
access faster for very large queues. The local and remote destinations
are processed by different programs, but the message is still stored
only once in queue/mess.

>How can we know the queue number used in each destination?

it's the same message file name. QP is the pid of the qmail-queue
process.

qmail doubts

[Fábio Eiki Doy]

We are undergraduate students of the Statistics Department
and we are working in a small research project. We are trying to
fit a queueing model for the e-mail delivery service.
In our Institute they use Qmail to handle the e-mail service.
We are using the log files produced every day by Qmail
to obtain the information about the movement of messages.
We have some doubts about the log files that were not answered
by the local administrators and we hope that someone can help us.

1) When the delivery of a message is postponed for the next
day, the sucessive log files regarding these postponned messages
do not have the same information as before. For instance birth
time and size are not present anymore. Since the message is
delivered, this information is hidden somewhere. Is there some
way to get this missing information?

2) Qmail has 23 queues for the local deliveries and 23 queues for the
remote deliveries. We were informed that the message choose the queue
across the relation QP (mod 23). A message to a list
have the same QP but each destination is processed in a different queue.

How can we know the queue number used in each destination?

We appreciate any comments.
Thanks.

Fábio and Gustavo.
