RE: [vchkpw] vmysql: sql error[3]: Lost connection to MySQL server during query - once again
I have tracked down the problem to the mysql threads timing out after 5 minutes (we are using the database server that handles authentication for other purposes, too) Just how busy is MySQL?

RE: [vchkpw] valid user patch
http://http.netdevice.com:9080/qmail/rcptck/ Does anyone know if any of these patches work with vpopmail and virtual domains? I really want to install something eliminate the insane amount of bounce messages in my queue. They are all sorry that user does not exist, and of course they are bouncing to invalid accounts since the spammer never puts a valid from header in their emails. It's driving me nuts, since my queue fills up with many thousands of these messages and is severely degrading the performance of my server. I have used interazioni's chkuser patch with great success: (http://www.interazioni.it/opensource/chkuser/) My queue has dropped from ~20,000 to an average of ~150, with an average load of 1 (Used to be ~8) Regards, MB
[vchkpw] 5.3.19 Upgrade - Suggestions on making it as painless as possible.
Just wondering if anyone has upgraded (relatively painlessly!) from 5.3.19 (qmail-1.03, Bill Shupps qmail-toaster-0.4.2.patch, MySQL) - 5.4.9 (Basing install on http://www.shupp.org/toaster/, but will be using MySQL)? Any gotchas/hints would be greatly appreciated. Regards, MB
RE: [vchkpw] Migrating an entire domain to a different server.
Hi Jean, Jean Wainer wrote: - Copy MySQL entries for domain to new server? (This is the step I am unsure about!) Well, you can do that. Or you convert the user base to CDB on the original server (~vpopmail/bin/vconvert -m -c $domain), copy the CDB file to the other server (inside the domain dir), then run vconvert on the new server (~vpopmail/bin/vconvert -c -m $domain). I prefer this way.. :) Ahh - Thanks! Any gotchas moving the 5.3.19 - Current Stable with vconvert? Regards, MB
[vchkpw] Migrating an entire domain to a different server.
Running vpopmail version: 5.3.19, with MySQL auth (I know - Have to upgrade!), and we have one client who wishes to move there domain to a new server - The domain contains about 400 accounts, and I was wondering the best way to migrate the entire domain? - Add clients_domain to new server - Copy /home/vpopmail/domains/clients_domain/* to new server - Copy MySQL entries for domain to new server?

RE: [vchkpw] User is over quota (whithout beeing over quota)
My users are reporting me they are receiving a warning message that they are over their user quota, but they know they are not over quota. Do note quote me on this, but i _believe_ the way to fix this is to remove the quota file, and it should be rebuild on the next delivery. It can also be caused when a user receives an e-mail that is greater in size than the users available quote - quotawarn is generated, but the mail bounces. Regards, MB
RE: [vchkpw] User-managed mailing lists in virtual hosting environment?
Complicating things (apparently) is that our mail server is separate from the Web server on which we provide clients' virtual hosts: I am hoping to be able to allow a customer to create (say) [EMAIL PROTECTED] (but ezmlm-web appears to want to use the canonical hostname for the mail server as the RHS of the email address). Is there some other choice I might plausibly make to support such lists? I don't know if this will be applicable in your environment, but qmailadmin (http://www.inter7.com/qmailadmin.html) has mailing list management functionalities. HTH, MB
RE: [vchkpw] Temporarily disable mail delivery to domain
I think I saw a qmail patch that let you use a badrcptto or badmailto file in /var/qmail/controls. Check http://www.qmail.org and search for badrcptto (there are two of them right together). If this works, it would reject the mail at the smtp level. Thanks for the info. I think rejecting at the smtp level would be the most efficient since you wouldn't have to accept the whole message then. I agree. Regards, MB
[vchkpw] Temporarily disable mail delivery to domain
Is there a simple way to temporarily disable mail delivery to domain (i.e. When a client has not paid there bill) Regards, MB
RE: [vchkpw] Temporarily disable mail delivery to domain
With the cdb back end it is easy, sql back ends might be a problem... Move their domain directory to a different name, then run vdeldomain on the domain. When they pay, run vadddomain, then move the directory back. If you are using a database, you could possibly use vconvert to copy the data from the database to cdb storage before moving the directory, then again to put it back once they pay. Another way would be to remove their domain from the files in /var/qmail/control and /var/qmail/users by hand. Remember what you remove, and from where. You have to signal qmail to reload the files once you are done. Thanks for the info Rick. Hmm...Think I'll just leave pop+imap disabled. Regards, MB Rick
RE: [vchkpw] Server Farm..
We have been running this particular setup for about a year now... I am happy with the overall performance, however when things break, they have a tendancy to break badly especially with MySQL's replication. We had a problem with our NFS store dropping out from under the NFS server* (the DBs were located on the same machine). This forced a hard restart on the server and when the server would come back up the replication in MySQL was broken between the master and slaves (the master had a different replication point than the slaves, the slaves were requesting a start position that didn't exist. The worst part is we didn't realize it initially until updates to users, etc weren't being seen on the slave servers). This forced us to down the local database servers (slave database servers). This did have the advantage of forcing vpopmail to look at the master server for reads and writes which was a nice fall back position, but the restoration process was difficult and depending on the amount of data in the vpopmail database, very time consuming moving massive database dumps to resync the databases on the slave servers. I have had to do this process about 5 times since we have started running this setup. Also if you are going to do this, be sure that when you do a mysqldump of your data (you are doing that nightly right?;) ) be sure to use the --master-data option so the slaves will know where to pick up replication with the master. Another tip... Turn off auth logging to mysql if you are doing replication... ICKY. Thanks for the info! How do you find NFS performance? (Did you use any special tweaking/mount options?) And what are you using for auth?(NIS/LDAP etc) We are currently looking at a load balancer solution (UltraMonkey/LVS or Foundry ServerIron, I would like to consider a Linux alternative, but majority of our support staff are not Linux savvy... still haven't decided but UltraMonkey/LVS is working well so far) with DRBD (http://www.drbd.org/) and heartbeat for both the database and NFS servers and cheap clones as the actual mail servers running a combination of qmail+vpopmail+clamav+spamassassin. Just out of interest - What are you using to sync data(configs etc) - You also mention NFS servers...So I assume you are running more than one behind a loadbalancer...how are you synching data between them? Regards, MB
RE: [vchkpw] Server Farm..
I don't think samba gives the proper filesystem semantics that would be needed for this to happen. Thanks! The other option though, is that vpopmail does support a master/slave setup where any writable queries go to server X while readable ones are done locally for performance. This is a better scenario than two way replication since you don't run the risk of replication breakage. [that] option sounds much better - If a writable query is performed, I assume I must have master/slave configured (Master obviously being the writable mysql server, which would then update all the slaves?) right. We have several of those types of installations up and running. Works pretty well. Ok - What happens if the master write server is unavailable...does vpopmail start writing to local read database? Regards, MB
RE: [vchkpw] Server Farm..
Never used remote logging for multilog so I can't tell you about that, but it looks pretty straight forward. NFS settings can be tweaked to improve its performance/bandwidth usage. I've only seen it chew up a ton of bandwidth when things aren't setup properly, or when a drive couldn't be mounted properly. Thanks - Would it be worthwhile running Samba only (The NAS will be serving both Win+Linux boxes)? As for your mysql two-way replication. Ordinarily I'd say this was a bad and evil idea, in the case of the vpopmail database it should be fine. Since they key their records with text fields and not numerical ones the risk of a duplicate key breaking replication is almost non existent. Both servers would have to add the same [EMAIL PROTECTED] at the same time, and what are the chances of that... The other option though, is that vpopmail does support a master/slave setup where any writable queries go to server X while readable ones are done locally for performance. This is a better scenario than two way replication since you don't run the risk of replication breakage. Second option sounds much better - If a writable query is performed, I assume I must have master/slave configured (Master obviously being the writable mysql server, which would then update all the slaves?) Regards, MB
[vchkpw] Server Farm..
I am in the process of migrating our qmail/vpopmail/webmail box to a server farm (Using ServerIron for Load Balancing) I have decided to log everything to a central log server (To simplify support and generation of stats), and came across the following: The following describes how to log to remote host using multilog and tcpclient: http://smarden.org/socklog/network.html Has anyone used the above - Or has comments suggestions on an alternative? I was also thinking of having mysql servers(2 to begin with) in a Mutual Master-Slave relationship (Sitting behind a loadbalancer), and have all qmail/vpopmail/webmail boxes connect to the one (Loadbalanced) IP for authAlthough I have never used Mutual Master-Slave relationship with MySQL, and do not know how effective it is? (If anyone has an alternate solution, please let me know!) We are building the NAS ourselves, and I have had a few reports that NFS was a total bandwidth whore - Therefore was considering running Samba only? Would also appreciate anyones experiences(Difficulty in setting up, scalability etc) with using either LDAP, Kerberos or (maybe?) Radius for auth - As I've heard NIS has security issues? Thanks in advance. Regards, MB
RE: [vchkpw] info for installations...

RE: [vchkpw] Automatic Folder creation
I thought about this patch, too... However, I've planned to
implement it
outside of vpopmail. Now I think that better place will be in vpopmail
itself, thanks for idea...
You could do it quite simply in a mailfilter:
Eg. My Spam mailfilter creates a SPAM folder if it does not already exist, then
delivers any messages marked as spam to the new dir:
if ((/^X-Spam-Flag:.*YES/))
{
`test -d ./Maildir/.SPAM`
if( $RETURNCODE == 1 )
{
`maildirmake ./Maildir/.SPAM;chown -R vpopmail.vchkpw ./Maildir/.SPAM`
`/home/vpopmail/subImapSpam.sh ./`
}
to ./Maildir/.SPAM/
}
to ./Maildir/
~
/home/vpopmail/subImapSpam.sh:
#!/bin/bash
IMAP=$1/Maildir/courierimapsubscribed
if [ -f $IMAP ]; then
CHECK=`cat $1/Maildir/courierimapsubscribed | grep INBOX.SPAM`
if [ $CHECK == ]; then
echo INBOX.SPAM $IMAP
fi
else
NEW=INBOX\nINBOX.Sent\nINBOX.Trash\nINBOX.Drafts\nINBOX.SPAM
echo -e $NEW $IMAP
chown vpopmail.vchkpw $IMAP
chmod 644 $IMAP
fi
