RE: [vchkpw] ldap or mysql
Is LDAP support of Vpopmail mature enough for a large production server? Has anyone used it succesfully in such a case? From README.ldap : Using vpopmail with LDAP is not very common. The LDAP modules are functional, but because it not as popular as using CDB or MySQL auth systems, you should be wary of implementing the LDAP system on a production server. I'm using Vpopmail+LDAP for about 2 years, with no problems. But, for older versions of Vpopmail, I had to do some nasty things in order to make it compile correctly. From README.mysql : Using vpopmail with MySQL is becoming increasingly popular. The code is well tested and can be considered to be just as stable as the default CDB authentication system. Michael. And you will have much more flexibility. I did choose LDAP because of this performance, but if I had to make the choice again, I would choose mysql instead.
[vchkpw] Vdelivermail high load
Hi all, Today, when issuing a top on my pop server, I noticed that there were some vdelivermails process eating a lot of cpu resources. Then, looking in the logs files, I saw that it was a spam to a specific domain, and this domain had the postmaster account as the 'catchall account'. What surprised me is the number of emails in the its Maildir: about 1479158 Is the number of emails in a Maildir related to the amount of cpu vdelivermail uses? I saw an increasing use of the disc too, somethings 100%... Thanks! ___ ALMEIDA, Fernando Costa de Computeasy Informtica www.computeasy.com.br BSD USER BSD050945 ICQ 72293951
RE: [vchkpw] Vdelivermail high load
Hi Jeremy, thanks for your explanation! Im using FreeBSD and consequently an UFS Filesystem (with DIR_HASH and SoftUpdates enabled). I will delete the emails, but I posted this question just to make sure that my problem was caused by the high number of files in the user's Maildir. The next step is to avoid that an user have so many emails in his Maildir, perhaps enabling quota for all users... I frequently face high IO loads in this server, even though its has one dedicated disk for the qmail queue and logs.

RE: [vchkpw] Vdelivermail high load
Yes! This account has a big quota (about 50MB)... Here is what I did: 1) Deleted all emails from this account; 2) Increased vfs.ufs.dirhash_maxmem to improve performance on big directories (Thanks to Jeremy who mades me read more about DIRHASH)... And now, I will set the users to NOQUOTA (thanks to you, hehe)... Another question... Is there a quota on this account? I've caught some maildrop and vdelivermail processes chewing up a ton of cpu just trying to recalculate the quota. Very similar situation; catchalls are evil and outdated. Since the user had an incredibly huge quota anyway, I set them to NOQUOTA with vmoduser and everything calmed down.

When issuing a top, I see a lot of process of vdelivermail eating all cpu resources: I bet you now have quota support enabled, and you did not before. Actually, I already had quota support enabled, but just for user accounts, not for the entire domain. That means that the first time vdelivermail attempts to deliver mail to an account it must scan all the existing mail to determine the file space being used. Can the new feature of domain quota be causing this behaviour too? Although I had enabled the domain quota support, I did not set any domain quota yet. Even in this case, will vpopmail still scan my domains in order to calculate these disk usages? You can either disable quota support, or just live with it. Once everyone has received their first new email their disk usage information will be cached, and the number of full directory scans will go way down. It is bad at first because every new message is to a user without cached disk usage information. Rick

[vchkpw] Almost working... vpopmail+maildrop+mailadmin
Hi,
After hours of fight my setup is working:
1) maildrop 1.5.0
2) vpopmail 5.2
3) qmailadmin 1.0.4
4) sqwebmail 3.3.3
I have just one problem:
I dont need to loose the catchall feature of vpopmail, so I cant use a
.qmail-default in the domain dir to instruct qmail to use maildrop. One
possible solution is to keep the .qmail-default untouched, and create a
.qmail-user for every user in the domain, with the following:
_
| /usr/local/bin/maildrop /etc/maildroprc
_
and maildroprc
_
VHOME=`/var/vpopmail/bin/vuserinfo -d $EXT@$HOST`
include $VHOME/Maildir/.mailfilter
_
the user .mailfilter contains the following:
_
#MFMAILDROP=2
#
# DO NOT EDIT THIS FILE. This is an automatically generated filter.
MAILDIRQUOTA=10S
FROM='[EMAIL PROTECTED]'
import SENDER
if ($SENDER eq )
{
SENDER=$FROM
}
##Op:contains
##Header:
##Value:teste
##Folder:*Seu email contem teste
##From:
##PlainString
##Body
##Name:Teste
to | /var/vpopmail/bin/vdelivermail '' bounce-no-mailbox
_
This way, I dont loose the vdelivermail features (like quota), and use the
maildrop filtering too. The .mailfilter file is created by the sqwebmail. My
problem is that this way, I will have to create a .qmail-user file to
every user in every domain, and maintain this sincronized How can I
avoid this? Im thinking in hack qmailadmin, but this is a 'last resort'.
Thanks in advance,

Thanks, now Im sending emails with maildrop with success.., but I still have some questions: 1) How can I make a .qmail-default and maildroprc that dinamically choose the user sender? What I want is to not put a .qmail file to every user in my domains, but instead justt a .qmail-default in the domain dir... 2) I have quotas support, but maildrop cant see them, since vdelivermail is the responsable to do this.. How can I do not loose the vdelivermail features, but use maildrop filters? Im reading about the seekable patch, and althougt I applied the patch sucessfully, vdelivermail seens to not see my emails.
