Anwering to myself... not really. The problem went away
temporarily. When load goes up again, it comes back.
So my last attempt was to rebuild vpopmail with these 2
more ./configure options:

--enable-file-locking=n --enable-logging=n

It's not the best thing to do, but well, we're moving all data
off from this server to a new server as scheduled earlier. :)

[vchkpw] File busy try again later error

[Kittiwat Manosuthi]

Hi List:

Our pop server is seeing a little more load recently and some of the users
are getting "File busy try again later" error when they tried to pop their
mail. I check the archive and found some people getting the same problem
recently but no answer. So I went to the source, and found that the error
msg is in file_lock.c with 2 #define in file_lock.h.

#define MAX_TRY_RLOCK   10
#define MAX_TRY_WLOCK   15

I did double those, and recompile and install, and the error seems to be
gone. Well, I don't know if this is the right thing to do, or there's any
other way to verify where the problem actually is.

Thanks,

If you want to increase the default quota for *new* users, then recompiling
would help.

But if you'd like to increase the quota of existing users, then
vmoduser -q
will be able to help you.

To run vmoduser against all users in your machine, Jonas Pasche's script
should be able to help you list all users.

for D in `awk -F : '{ print $5 }' < /var/qmail/users/assign | uniq` ; do
  if [ -e $D/vpasswd ] ; then
awk -v N=`basename $D` -F : '{ print $1"@"N }' < $D/vpasswd
  fi
done

Hey Jonas, I like this script very much! :-)

Cheers,

Re: how to _delay_ failed authentication

Well.. that's probably the way to go. Unfortunately, it's getting out of
my league now.  Anyone think this is an interesting thing to do?

Dear Ken:

This convenience feature is what I have been hoping for for a long

qmailadmin can't create ezmlm mailing list

[Kittiwat Manosuthi]

Qmail is working properly. Qmailadmin is also working when creating users
and autoresponder and other stuff.  But I can't create mailing list through
qmailadmin.  It says Internal Server Error!
What's wrong?

I installed all of them strictly as per the install file, ie., all on
standard locations.  No errors found during make.  Try creating mailing list
using ezmlm-make, it works.  Checking the list that it creates, and I found
1 user as per the install instruction.  But when injecting an unsubscribe
msg, there's a mail to me but nothing in it.  No removal number or anything.
Something might be wrong here, which I'd like to find out.

Help
thanks
