[vchkpw] maildrop with bounce-no-mailbox
Hi.. although this is a highly maildrop regarded question, I have to ask here, since maildrop folks seem to be unresponsive.. some of you are using maildrop together with vpopmail, usually somewhere in the maildirfilter file there's some line like VPOP=| /var/vpopmail/bin/vdelivermail '' bounce-no-mailbox to $VPOP this works totally fine, when the user exists. however if he doesn't, vpopmail exits 100, which seems to be a great problem for maildrop: any process not exiting 0 makes maildrop exit with code 75. this is especially bad, because 75 means for qmail to defer this message and try it again and again until the queuelifetime is reached. and we all know about those little spammers trying invalid usernames... so, how do you do it? use the chkuser patch for qmail, so no illegal users get into the queue? write a wrapper for vpopmail so that it exits 0 even when the user doesn't exist? use some hack for maildrop?? each way seems to have it's own disadvantage :/ -- Mit internetten Grüßen / Best Regards --- Justin Heesemannionium Technologies [EMAIL PROTECTED]www.ionium.org
Re: [vchkpw] Strange problem with SMTP AUTH
Hi Tom! Can anybody tell me what is happening here? Is it a problem with permissions? If yes, permissions of what file? Make sure your SMTP server is running as the vpopmail user. This seemed to be the problem although I actually don't know how that happened because it worked for quite some time. Anyway, at least it's working again now.

[vchkpw] [semi-OT] which is more portable?
grep vpopmail /etc/passwd | awk -F : '{print $6}'
or
grep vpopmail /etc/passwd | cut -d':' -f6
Reason I'm asking is I'm making some minor modifications to the Makefile for
the chkuser patch and I want to make sure they're as absolutely portable as
possible before releasing it to the masses.
I appreciate any input (including if /etc/passwd is not portable, it's been on
every system I've ever seen, but I'm relatively new to *nix compared to a lot
of you I'm sure) I can get :)
Thanks.

I would think that cut would be more portable. However, every machine
I've used has had some variant of awk installed too.
You might want to consider using 'grep ^vpopmail' or even 'grep
^vpopmail:' rather than 'grep vpopmail' to ensure that you're only getting
the 'vpopmail' user. (I have a server in which we've had to transparently
migrate users who were set up under sendmail so we have users whose home
directories are under the vpopmail directory. Nasty, I know.) The one
catch is that I don't know if 'grep ^string' is supported in all versions
of 'grep'.

I don't know of any portability concerns in this regard. I wonder if this
is just a design choice.

cut on solaris and sco clients (and I know its on the *BSDs), however
awk is a truly old school tool, and is almost gauranteed to be on all

/etc/passwd should be pretty portable however the field order I don't
think is specified in any POSIX or equivalent spec. Depending on what
info you're looking for you may want to see if something like perl's
builtin getpw function would work (perldoc -f getpw) since they've
ported perl to virtually every *nix on earth and have dealt with all of

ok, my initial intent was to use cut, so I think I'll stick with that.

good catch. Change made. The beauty of the open source community is shown :)

migrate users who were set up under sendmail so we have users whose home
directories are under the vpopmail directory. Nasty, I know.) The one
catch is that I don't know if 'grep ^string' is supported in all versions

POSIX regular expressions should be portable to any POSIX conforming unix
variant. I would think that any implementation of grep would be able to
handle that simple regex.

could be, although I know djb went to great lenghts to make his code as
absolutely portable as possible, and I don't want to stray from this :)
Thanks Chris.

argh, that's true. Probably why djb didn't just write his own /etc/passwd
parser when he complained about the reliability of getpwnam()
I will check around a little bit. If only 'id' had a -h flag for home
directory :)
I could have a simple C program get built that calls getpwnam() and returns
the home directory ... ugh can we say kludge? :)
maybe I'll just make conf-vpopmail be the path to vpopmail's home directory
and call it good. T'would be nice to be able to auto-detect it simply based
on the user vpopmail was configured with (considering there are probably far
less vpopmail implementations that use another user than vpopmail, than there
are ones that use something other than /home/vpopmail), but sometimes
sacrifices must be made :)
I will do it this way, and add a check just before qmail-smtpd is built to
make sure that $VPOPDIR/etc/{inc_deps,lib_deps} exist, and if not, spit out
an error.
Thanks everyone for your input :)

Re: [vchkpw] maildrop with bounce-no-mailbox
so, how do you do it? use the chkuser patch for qmail, so no illegal users get into the queue? write a wrapper for vpopmail so that it exits 0 even when the user doesn't exist? use some hack for maildrop?? I am also having the same problems. I hadn't noticed it until my queue was over 30,000 messages. I haven't had the time to work out a real solution yet. I didn't know if it was better to hack maildrop or hack vdelivermail since I haven't even looked into either one of them yet. What I had found was that one of my domains was receiving thousands of messages per hour for non-existent users and bouncing back. So as a quick fix, I set the default to delete, I shortened the queuelifetime to 3 days, and increased the concurrency settings because they were constantly maxed out. I'd also like to hear what real solutions people have come up with to deal with this.

Re: [vchkpw] maildrop with bounce-no-mailbox
In maildrop Make test for the user dir before process anything else. If the directory of that user doesn't exist than call a little perl prg. In the perl prg grep the domain .qmail file and check that there is a delivery to somewhere. (so catch all is exists or not) In my system if a user doesn't exists than it is bounced back to the sending server, so if I can't find a user Maildir than catch-all is enabled. (I don't remember the name of that qmail patch witch do this for me...) If there it is, then find out this new users dir, and send back this info to maildrop. Than process evrything as usual. Use vuserinfo and vdominfo.
