Re: [vchkpw] Custom Maildir Structure
Yes. I'm suggesting that we could use directory names outside of the user namespace so that you could have bigdir support and one-character email addresses at the same time. It would be difficult to handle existing domains though... There would need to be a lot of directory renaming and updating of the user database to pull it off. This is probably a silly idea but... You could always write a dot-file, e.g. .domain-version, that contains the 'version number' of the domain layout. If the file doesn't exist of if the 'version number' is, say, 1, vpopmail uses the old convention for bigdir. If the 'version number' is, say, 2, vpomail uses the new convention. A program could be written to convert between domain versions. The advantage to this is that it wouldn't automatically require conversion for new domains when vpopmail is upgraded. The disadvantages are that it may be overly complex/complicated and, well, it does seem rather silly. (That said, I use something like this on a website so I can track the versions of the SQL schemas so I can pass along intelligent upgrade scripts to the website maintainer.)

Re: [vchkpw] Modifying accounts with PHP
On Tue, 28 Sep 2004, a.h.s. boy wrote: I installed vpopmail with MySQL support, without valias support (as seems to be recommended). I've written some PHP scripts that can create and modify email accounts by direct interface with MySQL, but I'm looking for ways to do more administration of vpopmail -- creating aliases, adding domains, etc. I used to have an issue with valias but that has been fixed in newer versions of vpopmail. If you use valias, adding and deleting aliases is as simple as manipulating rows in the table. As mentioned on this list at the beginning of the month, you can essentially add users by adding a row to the table for your users (usually vpopmail) with an empty home directory. When an email is first delivered or the account is checked via POP3 or IMAP, the directory field is populated and the directory is set up. (Emails from this thread are also in the README.mysql file in vpopmail 5.4.7.) There is unfortunately no like mechanism for deleting users as far as I know. Adding/deleting domains requires modifying qmail control files so these would need to be done as root (unless you want to play ownership games with said files). There is work underway to create a vpopmail daemon that can parse requests from PHP scripts or other sources and make the appropriate changes. My understanding is that the existing PHP vpopmail extension has been obsoleted in favour of a new set that will use the daemon. Since .qmail files needs to be owned by vpopmail:vchkpw, and the v* applications need to run as root, I can't really have Apache/PHP try to accomplish any of that stuff directly. What I'm thinking right now is that I could write out formatted text files to a specific directory, then have a cron job (running as root) that parses them and executes various commands: vadddomain, valias, etc. That would work. I do something vaguely like that for deleting users through my vpopmail admin module for squirrelmail already. (Really what I do is put the information for the deleted user into a separate table and take the user out of the vpopmail table. A perl script then handles archiving/deleting the user data.) Another method, advocated by some people, is to run a separate copy of apache with the user vpopmail and group vchkpw. I don't like this solution at all. (Which is why I ended up writing my own admin module. Maybe my boss will let me distribute it. I must remember to ask him...) There's always suexec (and mod_phpsuexec) but I don't like that solution much either. Sincerely, Chris Ess System Administrator / CDTT (Certified Duct Tape Technician)
Re: [vchkpw] Vpopmail migration
I've a mail server which I've installed qmail1.03 with vpopmail-5.2.1, MySQL 3.23 and qmailadmin. All email users are stored in MySQL's vpopmail database (in vpopmail.vpopmail table). Yes, 1 table for all users in different domains. Now, I am migrating everything to another machine. On that machine, I've installed netqmail, vpopmail 5.4 and MySQL 4.0. Everything goes fine. But in the final stages, I need to migrate all user accounts with their passwords, sql tables, domains and their leave mail on servers' mails to the new machine. I can't find any docs about migration, backup and restore to a new server. Can anyone help me? I am installing everything on RedHat's Fedora Core 2. Here's my stab at it: On the new server, add all of the domains with vadddomain. This takes care of the domains. Then, when done, drop the vpopmail table and clear out the contents of /home/vpopmail/domains This will be replaced below. On the old server, generate a dump of the vpopmail table with mysqldump. Import this into your other server. This takes care of the passwords and SQL tables. Assuming all of your users are virtual, you should then be able to just tar up the contents of /home/vpopmail/domains (or whatever you use) and then untar in the equivalent directory on the other server. That should take care of the email and directory structure. Warning: I have never used this process in practice and, well, it may not work as expected. I'm pretty sure someone else has better directions. Sincerely, Chris Ess System Administrator / CDTT (Certified Duct Tape Technician)

Re: [vchkpw] vpopmail + billing server integration
I'd like to connect via an encrypted shell, like SSH, but I'd also like the connection to be persistent, to avoid connection costs for batch operations. I'd also like to provide a FIFO queue mechanism so that if the mail server reboots, anyone working on the billing server won't get error messages when they attempt to provision services. Then, when the mail server comes back up, the SSH tunnel is re-established and the queued operations begin to execute. However, so far in my google searches I haven't seen anything that would help me implement a persistent SSH connection with a FIFO queue. Can anyone give me tips? Have you considered 1. A VPN between the two? 2. Using an on-demand connection method rather than a persistent method? 3. Just connecting to a dedicated socket or service rather than SSH? 4. The security issues inherent in connecting your billing server to your mailserver? To keep this topic vaguely vpopmail-related, have you considered keeping all of the necessary vpopmail information (or at least most of it) in a MySQL database or some other separate data repository and having something on your billing server update that? (Or, alternatively, why not run the MySQL database on your billing server if you go that route? That gets around the connection issues mentioned above although it does not fix any possible security issues.) Sincerely, Chris Ess System Administrator / CDTT (Certified Duct Tape Technician)

Our CSRs see the billing server pause while the hook executes to provision a service. I want to keep that pause time to a minimum. That depends on if a scripted SSH connection or whatever you use takes a long time to execute. When I used it, the Net::SSH perl module is pretty fast and added negligible time. 3. Just connecting to a dedicated socket or service rather than SSH? Not secure, and how would that work? I thought vpopmail's only manipulation system is either SQL or command line based... It would work however you want it to. This suggestion would require building your own methods (or finding something someone else has done). You could make it as secure or as insecure as you like. You might also want to look at the vpopmail daemon in development. (Which reminds me that I need to subscribe to that list.) 4. The security issues inherent in connecting your billing server to your mailserver? Sure. People do it all the time, right?

Re: [vchkpw] [semi-OT] which is more portable?
grep vpopmail /etc/passwd | awk -F : '{print $6}'
or
grep vpopmail /etc/passwd | cut -d':' -f6
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'.
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.
also, while on the topic of portability, I noticed that djb does not include
ANY variable substitutions (only backtick ` ` substitutions) in his Makefile.
I'm curious if this is also for portability reasons. Anyone aware of any
implementations of the 'make' program that don't understand variable
substitions in Makefiles, or any situations (lack of /bin/sh compatible
shell, perhaps?) that might make variable substitutions not possible?
I don't know of any portability concerns in this regard. I wonder if this
is just a design choice.

Re: [vchkpw] [semi-OT] which is more portable?
[snip] right, which is why it's better to just specify it in conf-vpopmail. However, I'm having trouble getting that value into a variable in a Makefile, so I'm thinking that just setting it at the top and pointing documentation to change it would be best. Why not just use the backtick substitutions like you pointed out djb does? This gets around dealing with Makefile variables and prevents people from needing to edit the Makefile.

See this sentence from http://www.inter7.com/vpopmail.html : Inter7 has developed vpopmail (vchkpw), a free GPL software package, to provide an easy way to manage virtual email domains and non /etc/passwd email accounts on your qmail or Postfix mail servers.

Perhaps, for a 'best of both worlds' (or 'horrible compromise') idea, maybe we should have configure switches so that we can build static vchkpw and vdelivermail binaries (since these are the two most run programs under vpopmail as far as I can see) and yet still build the shared library for linking with other binaries, including vadddomain, qmailadmin, courier's authvchkpw module, etc. I think that any performance hit we might take by making vadddomain and the other binaries link against the shared library would be tolerable.

Or am I confused? After rebuilding vpopmail with --enable-roaming-users=y in step 2, you should then recompile Courier to ensure that it is linking against the new (and proper) version of libvpopmail.a Changing the vchkpw binary will not affect Courier since, as Mr. Collins says, Courier links directly against the library and does not ever deal with the vchkpw binary.

[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.
