Re: [vchkpw] qmail-default, bounce and reply
I can't say for the qmailrocks version, in standard chkuser 2.0.8 you have new defines that may help you. CHKUSER_ENABLE_ALIAS_DEFAULT Enables checking of .qmail-alias-default files You may try to keep your patched qmail-smtpd.c and copy newer chkuser.h, chkuser_settings.h, chkuser.c, then change settings, compile and see if you have reached your goal.

Re: [vchkpw] vpopmail and nfs
I assume CentOS is some kind of Linux? The email below is geared toward
Linux.
File busy try again later!
Failed while attempting to update_file() the assign file
Error. Failed to add domain to assign file
Error: Could not update file
Let's see if we can use the source to figure out what's wrong.
In vpopmail.c, the code is trying to append a line to the assign file.
To do this with FILE_LOCKING defined, the update_file routine needs
to open and lock assign.lock. If it doesn't, it complains:
Failed while attempting to update_file() the assign file
The update_file routine calls get_write_lock to do its dirty work.
Here's the routine in file_lock.c:
int get_write_lock( FILE *fs )
{
int try = 0;
while(write_lock(fileno(fs), 0, SEEK_SET, 0) 0)
{
if (errno == EAGAIN || errno == EACCES || errno == ENOLCK )
{
/* there might be other errors cases in which
* you might try again.
*/
if (++try MAX_TRY_RLOCK) {
(void) sleep(2);
continue;
}
(void) fprintf(stderr,File busy try again later!\n);
return(-1);
}
return(-2);
}
return(0);
}
The write_lock() routine is a wrapper for fcntl(). If you look at
the fcntl(2) man page, it lists many reasons why it would fail.
Based on your second email, it's not permissions. Some other program
must have a lock on the file and is not letting go, or there's some
other odd problem (NFS? extended attributes?).
I have a few suggestions to help debugging:
1. Run strace -f /home/vpopmail/bin/vadddomain ...etc
Look at the output right before the printf of the error messages
for the return value from fcntl.
2. Run lsof assign.lock after it fails to see if there are any
other processes that have the file open. This would be done on
both the client and the server.
3. Add the following line before the line that has ++try MAX_TRY_RLOCK:
(void) perror(Debug write_lock: )
Then recompile vpopmail, install it, and try it again (don't forget
to make backups!). You'll hopefully get a reason for the locking
failure printed when it happens again.
4. Restart the NFS client and the NFS server and try again (stale lock).
Also, something you might need to do is make sure your NFS server
doesn't clobber UID names. I noticed in one of your emails that
assign.lock was owned by nfsnobody. The export options on the
NFS server should use no_all_squash,no_root_squash,async,rw.
On most distros, no_all_squash is the default option, but your
distro might have it set the other way.
Other NFS stuff:
1. The client needs to use NFS V3 for fcntl locking to work.
See this article:
http://www.quepublishing.com/articles/article.asp?p=23618seqNum=4
2. Is nfslockd running on the client?
3. Is the NFS client and NFS server running the same OS? If not,
could there be some compatability issues?
Hope this helps.

PS: If all else fails, install vpopmail on the NFS server and run the
administrative commands (vadddomain, vadduser, etc.) on the NFS server.

The problem is definitely acquiring the lock. Have you restarted nfs and
nfs-locking on both sides post power outage? This is almost definitely a
straight-forward NFS locking issue.
Hope that helps,

You'd have your say, /var/qmail2 qmail-send running, and use /var/qmail2/bin/qmail-queue to queue the mail, and it would have your smtproutes and stuff. also, you'd have to either nfs mount or make a local copy of your domains directories so the chkuser patch can look for .qmail files and such. -Jeremy -- Jeremy Kitchen ++ Systems Administrator ++ Inter7 Internet Technologies, Inc.

RE: [vchkpw] vpopmail and nfs
I assume CentOS is some kind of Linux? The email below is geared toward Linux. Yes, CentOS is a 100% compatible rebuild of Red Hat Enterprise Linux. The write_lock() routine is a wrapper for fcntl(). If you look at the fcntl(2) man page, it lists many reasons why it would fail. Running strace and reading the fcntl man page brings me to the following return value: ENOLCK Too many segment locks open, lock table is full, or a remote locking protocol failed (e.g. locking over NFS). To me it seems like a NFS locking problem, although I'm just guessing. 2. Run lsof assign.lock after it fails to see if there are any other processes that have the file open. This would be done on both the client and the server. Running lsof assign.lock after the vadddomain command fails on both the client and server had no output. 4. Restart the NFS client and the NFS server and try again (stale lock). Tried restarting NFS client and server, no luck. Also, something you might need to do is make sure your NFS server doesn't clobber UID names. I noticed in one of your emails that assign.lock was owned by nfsnobody. The export options on the NFS server should use no_all_squash,no_root_squash,async,rw. On most distros, no_all_squash is the default option, but your distro might have it set the other way. Previously, the folders were exported as (sync,rw). The thought was on data reliability in a harsh network environment. I've since changed the export options to (no_all_squash,no_root_squash,async,rw). This hasn't made any difference. The thing is, this used to work before the power outage, so I can't imagine it's a configuration issue. 1. The client needs to use NFS V3 for fcntl locking to work. I've since changed the mount options in fstab to rw,hard,intr,nfsvers=3 to force NFS v3, no luck. 2. Is nfslockd running on the client? I was able to confirm rpc.statd and lockd were running: rpcuser 13578 0.0 0.1 1664 740 ?S14:41 0:00 rpc.statd root 11464 0.0 0.0 00 ?SW Jan18 0:00 [lockd] 3. Is the NFS client and NFS server running the same OS? If not, could there be some compatability issues? Yes, the NFS cilent and NFS server are both running the same OS. Hope this helps. Thank you very much for your efforts! They have proven very helpful in troubleshooting this issue. I wouldn't have known where to begin otherwise. PS: If all else fails, install vpopmail on the NFS server and run the administrative commands (vadddomain, vadduser, etc.) on the NFS server. I'd love to except the NFS server is connected to a private network, only the management box is connected to the private network and the internet.

I thought I had seen people using this tiered approach with vpopmail and chkuser, just no details on implementation. I'm pretty sure vpopmail verifies the domain exists as a vpopmail domain by looking at the qmail/users/assign file (at least it does here with 5.4.6), so you should be able to do what you want if the chkusr patch relies on vpopmail calls (which it did in 1.0, I haven't used the 2.0 version yet). I missed the earlier messages on this topic so I'm not quite sure what you want to do but if you want a primary MX to accept mail and then forward it on to a second machine that does local delivery, adding the domain on the primary MX, then removing it from virtualdomains and adding into smtproutes *should* work. I did do a similar setup for a client but I was using cdb not mysql, and duplicating the vpasswd files for each domain and that did work. Should be easy enough to do the same thing with mysql although I think you'll have to manually add the domains to the assign file and rebuild it yourself if you are using the mysql server of the local delivery machine, plus add the domains vpopmail directory and .qmail-default file and any user .qmail files... yesh. Ummm, manually add the domain to assign, rebuild and nfs mount the vpopmail domains/ directory :) Did that make any sense at all ? Regards, Rick

There is normally nothing wrong with the Maildir itself most of the time. J-W Regeer
