Subject: Re: gdbm_open failures (was: Can't add user to apop database)
Qpoppers,
More info: I found that I could get an error string using
gdbm_strerror(gdbm_errno), and this reports the error "can't be writer"
(GDBM_CANT_BE_WRITER). So what causes this error? A quick web search
turns up documentation for gdbm_strerror but not what the specific
error codes actually mean. I fear I'll have to unpack the gdbm sources
and find out what generates that code.

Subject: Re: gdbm_open failures (was: Can't add user to apop database)
Qpoppers,
Yet more info: I found that GDBM was failing to acquire an exclusive
lock with flock, and when I stepped through the popauth.c code, I found
that the raw file was being opened with open() and then the resulting
handle was never used. Looks like some obsolete code that was never
expunged.
For reference, I'm using the qpopper-qmail-2.53-1-PAM.src.rpm package
to build from. This includes a couple of patches for qmail and PAM, but
neither patch touches popauth.c. The package is available from the
contrib directory at Red Hat. I can provide an updated source and
binary package.
Here's the diff:

The URL addresses a problem in the in.qpopper program. My problem was
in the popauth program, and was a result of what appears to be some
stale code left behind in the source that opened the raw APOP DB file
and prevented gdbm_open from getting exclusive access to it.
It may be that RH5.2 Linux treats locks differently than other
platforms, and so this problem hasn't been seen elsewhere. popauth was
opening the raw file, then invoking gdbm_open, which opens the file and
then flocks it. So the process had two outstanding opens on the file
before the flock. Perhaps there's something odd going on in the flock
code of the 2.0.36 kernel I'm using that's stroked by this sequence.

Possibly a FAQ, but what should I check if I see 4 messages in my mbox
in /var/spool/mail but qpopper (2.53) reports that I have 0? (I telnet
in and manually enter my user name and password and that's when the 0
messages is reported.) Is there a #define that perhaps I have goofed

Subject: corrupted From lines
Anyone seen corrupted "From " lines? Lately I have been seeing occasional
emails with the VERY FIRST LINE (the "From ") line corrupted in one the
following manner:
a) The very first letter is missing altogether (the "F") so the line
begins with a "rom" instead of "From"
b) There are extra "F" characters in the From line so it reads like this:
FFrom
instead of
From
Anyone seen this?
When this happens the email is unreadable, much to the annoyance of the
affected user (keeps getting prompted for password).
We are running on a Linux box, sendmail 8.9.3 (happened on 8.8.8 as well)
qpopper 3.0 (also happened with qpopper 2.52) and have several thousand
users using the mailserver all day long. Only occasional messages are
corrupted but it happens often enough that we have had to write a dumb
awk/sed script to seek out and fix this very annoying problem everey hour
(cannot run it too frequently otherwise cpu will be bogged down, there is
typically 300megs - 500 megs of email in the mail directory at any given
time).

Where can I find the updated procmail? :-) I don't have the corruption,
but can be a useful news. I'm gonna to test cucipop against qpopper
this week, so I want to post a result. The damn problem is that It don't
want to run on a port other than 110 =)

Hi Mike,
I'm not sure you are interested, but I wrote a simple perl script
that doesn't seem to impact our system performance. I wrote
it a while ago after our server crashed and corrupted a number
of inboxes. We have nearly 4000 users and this script can complete
the task of checking for corrupted mail in about 30 seconds on our
spacr server 1000.
Anyhow, attached below is the script.

Use at your own risk! While I believe there is no issues in using
the following script, as we have used it for more than a year, I
can offer no assurances that it will behave as expected.
Review the script before running... blah blah blah... :-)
#!/usr/local/bin/perl
#
# Check the /var/mail directory for corruptted mail folders.
#
# Grab the first line of /var/mail/<file> and make sure it
# begins with 'From'
#
$log = "./log";
$dir = "/var/mail";
-e $log and die "File $log already exists\n";
open LOG, "> $log" or die "Could not create $log: $!\n";
chdir $dir;
opendir DIR, "." or die $!;
while($file = readdir(DIR)){
# make sure it is a file, it has size, and it isn't a <file>.lock
-f $file and -s $file and ($file !~ /.lock$/) and do {
open F, $file or die $!;
# grab the first line
$line = <F>;
# if it does not start with From print it to the log file
$line =~ /^From/ or print LOG "/var/mail/$file\n";
close F;
};
}

It's definitely there, as part of a pseudo-message put there by the
ipop3d daemon included in the imap package. I switched back from
qpopper to ipop3d and instantly downloaded all the waiting messages.
I'm thinking this has something to do with the separator character
between messages. I don't see any non-printables in the file. Could
that be the issue? Incoming mail goes through sendmail 8.9.3, and
procmail is configured as the local delivery agent. I don't see an
/etc/procmailrc, so it must be using compiled-in settings from the
stock Red Hat 5.2 setup.

You can compile with the NO_STATUS flag defined, and qpopper will not
write X-UIDL or X-Status headers (qpopper will recalculate the UID
for every message every time).
However, since the problem indicates a locking issue, the spool file
may still get corrupted. There have been problems with locking over
NFS.

Hi,
I have been trying to run qpopper 2.53 with Mac OS X server, and I am
having one doozy of a weird problem. (everyone else on the Mac OS X
server list at Apple seems to run it fine ?!?!) I set everything up,
but when I telnet to the pop3 port, I get a connection, and then the
connection gets closed. If I check the system log, I get a message
like "can't execute usr/local/libexec/popper permission denied"
The path is correct, and the permissions on the file and folders are
correct (everyone can read and execute). I have tried putting popper
all over the place, same trouble. If I go to
usr/local/libexec/popper and type ./popper, it returns to the prompt
fine, but the system log has
Oct 11 13:57:26 localhost ./popper[682]: Unable to obtain socket and

I have reinstalled the system, and used both a precompiled qpopper

the solution??

are you leaving out the first / from /usr/local/libexec/popper in
inetd.conf or is that just a typo in your mail?

Subject: 2 bugs with qpopper 2.53 ?
Date: Fri, 15 Oct 1999 11:31:54 +0200
From: Gildas PERROT <perrot at FranceNet dot fr>
Hi,
I am using qpopper 2.53 on BSD/OS 3.1 server with bulletins configured (-b
/var/spool/bulls and ~.popbull created). The mail is only delivered by
sendmail in a local filesystem.
I noticed 2 problems which occur sometimes :
1) some mailbox are corrupted ("Unable to process From lines (envelope),
change recognition modes"). I know that I can edit the mailbox to correct that
but this can't be a solution for a host with thousands of mailboxes. My
questions are :
- what is the cause of that corruption and how can I avoided it ?
- is there a script I can run to clean a corrupted mailbox ?
2) sometimes, when reading a mailbox after a new bulletin is added, that
bulletin is appended to the last message without a separating blank line (it
just occurs for certain mailbox so it is not due to the bulletin itself). The
result is that the bulletin is not seen by qpopper as a separate message but
as text appended to the last message. My question is :
- what is the cause of that bug and how to avoid it ?
Thanks in advance for your help. Gildas.

Hi,
I am having a problem at the moment which is not related to Popper but I'm
hopeful of getting direction from this mailing list.
The MX record for the customer on the name server is
MX 10 mail
MX 20 mail.innetix.com.
mail A 209.172.33.40
Now for some time the mail (209.172.33.40) has been down therefore the mails
should be queued in mail.innetix.com server. The customer is unable to
retrieve emails. I need to know where is the queued mail for this customer
stored so that I can forwad the mail or delete the queued mail.
Thanks,
Sonia.

Content-Type: text/plain; charset=us-ascii

At Compaq, (previuosly known as Digital Equipment Corporation)
we use C2 security for enhanced security. Hence if a user has a POP3
account on a C2 secure
system, he is validated using a C2 library call 'sia_validate(user)'.
The problem is that the user's password is still entered and
transmitted as clear text.
* I wanted to know whether there is a better way to do it.
* What about other Operating systems who used enhanced security with
POP?
Is the POP password enetered and transmitted in clear text too
I would appreciate any comments or sugesstions
regarding this.

Type 'mailq' on your mailserver to see if they are waiting to go out. If
your customer sends a relevant ETRN command to your mailserver it should
begin to queue mails that it has for the domain to your customers
mailserver. I put up a quick USENET article I wrote long ago on
http://smtp.shellnet.co.uk/etrn.html, check that out if you need to learn
about ETRN.

Subject: Recently, qpopper dying frequently under normal load
Hi,
We have been running qpopper for happily years on RH Linux systems.
Lately, for the last 2-3 weeks we have been experincing a lot of problems
with qpopper. It seems to die for no obvious reason, many times a day,
particularly during the hours of 10am-4pm EDT, Monday thru Friday. Off
peak times are fine, no problems. We have not had a sudden increase in
traffic at all, i.e. all traffic levels are "normal" far as we can tell,
especially SMTP and POP3. We have tried qpopper3.0b15, qpopper3.0b18 and
qpopper2.53 all die frequently the same way. We have 3000-4000 mail users
on the server. I.e. the problems are not caused by a sudden increase in
server load or "overload".
Has anyone else noticed this lately?
My guess is that there is a new release of some mail client (Eudora, MS
OutLook, Netscape being the 3 most popular) that has a bad "killer bug"
for the qpopper POP3. We noticed that some mail clients (almost impossible
to identify which one) start several telnets in rapid succession, to our
POP3. For example, 5-10 telnet requests within 2-3 seconds. This is not
restricted to a single location (our clients are all over the map,
nationwide and worldwide). Could this be causing a problem and if so what
is the fix? Could there be any other problems causing this?
Any input would be appreciated.
regards
Mike Salim.

Madhavi,
Have you considered APOP? It probably does what you want it to.
As a side note, I think that it is still considered a courtesy to not
send HTML-formatted e-mail to lists -- opinions may differ.

Subject: QPopper authentication problems
Hello!
We've been running a couple of different versions (currently 2.53) of
qpopper on our SPARC 20 with 12,500 users, and have been having some
problems with authenticating users. There are several symptoms:
1. Clients take forever to authenticate, sometimes timing out at 45
seconds, their progress window stuck on the "pass" command. After auth,
things move quickly. Sometimes they timeout on the "quit" command.
2. The console reports a lot of errors (sometimes a couple a second)
"unable to get the canonical name of client err=0 (or 145)" or,
occasionally, though not often "-ERR too few arguments for the auth command"
Other info - These symptoms are more prevailent when the load is higher
(2+) but can occur anytime. Other authentication processes (telnet, sshd)
are almost immediate.
I've heard there is a way to make a binary database from the passwd files
to speed auth up, but don't know how or what needs to be done with qpopper
to make it do so. Maybe the problem is some other configuration issue.
Any help would be appreciated.

You're probably seeing a bug that's known about.... someone (sorry if you
*are* someone, forgot your name :-)) posted a patch to this list not very
long ago. Are you runnining with --enable-servermode?
Look at pop_dropcopy.c, around line 192 (my qpopper is pretty hacked up so I
can't say it's exaclty that line), you'll see:
/* Open the user's maildrop, If this fails, no harm in assuming empty
*/
if ((mfd = open(p->drop_name, O_RDWR)) > 0)
/* Lock the maildrop */
Change the line beginning "if" to read:
if ((mfd = open(p->drop_name, O_RDWR | O_CREAT, 0600)) > 0)
Recompile, and see if that works for you.

I don't feel I'll know enougth to answer that question, so I wont :-) ...
but as a suggestion, try a different authentication mechanism? The MySQL
auth patch(es) work for me, but not with that kind of userload yet.

The 'too few arguments' is basically broken clients trying to use the AUTH
command for APOP. Using APOP might help you speed up your authentication
requests, but to use it you'll have to tell the clients that they'll should
try to.
I can only suggest that your canonical name errors are due to your DNS
servers becoming overloaded OR (more likely) having no records for the hosts
that are trying to connect and unable to answer queries within a given
amount of time. It's basically telling you that it couldn't resolve the DNS
name of the client.

Sounds like whatever receives the mail (usually sendmail) isn't getting
it into the mailbox. Check the maillog file to see if the message is
getting rejected or dropped for some reason.
