[vchkpw] vpopmail maildrop
Hi, I just installed vpopmail 5.5.0 especially for the domain quota function which seems to be working fine. If I deliver through vdelivermail, quota enforcement does it's job but if I switch to maildrop for some filtering, I must apply maildrop / courier quota enforcement. Is there a way to first check for quota (user and domain) using vusaged and then pass the message to maildrop? I guess I have to use the .qmail file for this but I don't know how to combine both (vdelivermail and maildrop). Thanks for the help, Arthur !DSPAM:4b9defd532711438716412!

[vchkpw] Vpopmail + maildrop
Hi All,
I have problems configuring vpopmail and maildrop
to work.
when i use maildrop, all mails to my local domain
fails.
but mails that are sent from my domain to remote
domain, is working fine.
meaning to says there is something wrong for my
incoming traffic. (qmail-lspawn)
my current .qmail-default look like
this
| maildrop mailfilter
and my mailfilter
VPOP="| /home/vpopmail/bin/vdelivermail ''
bounce-no-mailbox"VHOME=`/home/vpopmail/bin/vuserinfo -d [EMAIL PROTECTED]`if ( $SIZE 262144
){ exception
{
xfilter "/usr/bin/spamc -f -u [EMAIL PROTECTED]"
}}
if (/^X-Spam-Flag:
*YES/){ # try filtering it
using user-defined rules exception
{
include $VHOME/Maildir/.mailfilter
} # then try delivering it to the
Trash folder exception
{
# to
"$VPOP"
to "$VHOME/Maildir/.Trash/"
} # or uncomment the following to
send it to the .spam folder #
exception {
# # to
"$VPOP"
# to
"$VHOME/Maildir/.spam/" #
}
# if not
go on with delivery exception
{
to "$VPOP"
}}else{ exception
{
include $VHOME/Maildir/.mailfilter
} exception
{
to "$VPOP" }}
my qmail is not running on service or supervise (i
took over from other, so i cant do much)
its using rc directly and my /var/qmail/rc look
like this
#!/bin/sh
# Using splogger to send the log through
syslog.# Using qmail-local to deliver messages to ~/Mailbox by
default.
#exec env - PATH="/var/qmail/bin:$PATH"
\#qmail-start ./Maildir/ splogger qmail# when QMAILQUEUE is set, all
mail will be sent to the nominated
scriptQMAILQUEUE="/var/qmail/bin/qmail-scanner-queue.pl" export
QMAILQUEUEexec env - PATH="/var/qmail/bin:$PATH" qmail-start '|
/usr/local/bin/deliverquota ./Maildir/ 3072000S | dot-forward .forward' splogger
qmail
I have tested my qmail-scanner with spamassassin
with clamav and they are working fine.
I have used the tests provided in qmail-scanner,
contrib directory
How do I test maildrop if its working
fine?
This is because when running "maildrop mailfilter"
in my shell, it just stop there.
How do I check if $EXT and $HOST have been
successfully passed in?
Thank you.

[vchkpw] vpopmail + maildrop + SQL valias delivery issue problem/kludge
Applicable versions:
vpopmail 5.2.1 and 5.2.2
maildrop 1.6.3
MySQL 4.0.16
I don't have a test server set up to use 5.4.0-pre1 but I may get around
to that sometime this next couple of weeks. (By which time we'll have a
new 5.4.0-pre# version probably.)
The basic issue is one that had been reported before on this mailing
list... If I call vdelivermail in maildrop to handle aliases, it spawns
vdelivermail and says it handles an alias... But it just simply does not
forward the message.
An example set of lines from my mail log is:
(I have changed the domain names for various reasons)

At the time, [EMAIL PROTECTED] was supposed to forward back to
[EMAIL PROTECTED]
After a bit of playing around (including changing vdelivermail to use a
Perl script rather than qmail-inject), I decided that the problem was
that, for whatever reason, qmail-inject was stopping before it had the
opportunity to finish. My guess is that a signal was being passed to it
that caused it to terminate. Unfortunately, I don't know what signal that
is since I didn't think to try to add signal handlers to my Perl script.
Also, unfortunately, I don't know if the signal is being issued by (or as
a result of) vdelivermail or maildrop. (I seem to recall reading
somewhere that a child process is passed a signal if the parent dies.)
I came up with a fix, but it's rather a quick kludge and really should be
replaced with something better. My fix was to add a sleep(2) after
vdelivermail.c closes the write file descriptor to the qmail-inject child.
So the 'if (inject == 1)' block looks like this:
if ( inject == 1 ) {
close(write_fd);
sleep(2);
return(0);
}
(In 5.2.2, the sleep(2) is line 599.)
The theory is that after two seconds, qmail-inject should be done and then
vdelivermail returns.
This works on both the development and production mailservers I run
without issue.
As I said, it's a nasty kludge, but it may be useful for those of you who
experience this issue.
If you have any better suggestions or think I'm chasing the wrong bug, do
let me know.

Re: [vchkpw] vpopmail+maildrop, sql valias loses mails
Look in syslog (/var/log/messages) when that problem happens.
Look for vdelivermail. Do you see any vdelivermail coredumps?
If yes, then this is the same problem I had, which is most likely related to
vdelivermail not handling certain maildrop exit codes (I dont recall them off
hand)
So as a workaround, try this:
SHELL=/bin/sh
import EXT
import HOST
VHOME=`~vpopmail/bin/vuserinfo -d [EMAIL PROTECTED]
`test -d $VHOME/Maildir`
if ( $RETURNCODE == 1 )
{
echo Sorry, no mailbox here by that name. (#5.1.1)
EXITCODE=100
exit
}
# Default delivery
exception {
to $VHOME/Maildir/
}

Out of 10 mails sent to [EMAIL PROTECTED] usually 4 lose, 6 gets

What should I look for?
I debugged what's happening with vdelivermail:
It always gets the mail, and looks up the valias.
When things okay, it runs a second delivery, but this time to the final
Maildir.
Sometimes this step missing.
More strange: 100% success when an alias comes from dot-qmail file, or
when the valias points to a different domain (no matter if local or
remote).

[vchkpw] vpopmail maildrop
Hi, after fiddling around with my mailserver configuration, everything seems to work now except for one thing. I'd like to Catch-All non existent accounts to postmaster, so i tried to change the delivery instruction in .qmail / .qmail-default to filter messages to postmaster. the problem is, that once i change the delivery instructions, i catch ALL mail, even to other existing accounts. anyone got a clue (although this may be a little offtopic on this list) ? Thanks, till

In your maildrop filter you could have something like...
# Get maildir to deliver to
VHOME=`/home/vpopmail/bin/vuserinfo -d [EMAIL PROTECTED]
# If it wasn't a valid user... set user to postmaster
if ($RETURNCODE != 0)
{
EXT=postmaster
}
That would probably do what you are after.
