So you want to replicate all account data and email-boxes to the other office, too ? As described, you can have a master-mysql-server and any number of slaves, but there's usually only one NFS-server for the maildirs. I think NetworkAppliance sells software for their NetApp Filers to replicate them and create a high-availability configuration even for NFS. But usually, if you have to ask about something like that, it's allready too expensive ;-) Rainer
[vchkpw] RE: Redundant server
Has anyone who is running vpopmail/qmail/mysql created a backup/redundant or even a secondary server for the same domains? Im looking to do that and I was wondering if there was any documentation available. Also is there any documentation I can read on how to properly backup the e-mails, users, config files on the setup stated above. I am running that on redhat 9. Any assistance will be greatly appreciated.
Re: [vchkpw] RE: Redundant server
This doesn't have anything to do with vpopmail. Very simple qmail config. On your secondary server, add the domains for which you are running backup to rcpthosts. Then add the backup server as a lower priority MX to your DNS. The qmail server on the backup machine will accept the mail, realize they are not locals (since they are NOT found in virtualdomains on the backup server) and forward them to the primary. Not sure what you mean about backing up the secondary, this doesn't really have to do with this service. However you back up the server in general ought to be just fine for backing up any queued mail as well. -- Jamie Thursday, June 3, 2004, 11:31:30 AM, you wrote: DP Has anyone who is running vpopmail/qmail/mysqlcreated a DP backup/redundant or even a secondary server for the same domains?

Re: [vchkpw] RE: Redundant server
On second reading I may have misunderstood your question, are you trying to load balance between two servers for a single domain? If that is the case a pretty simple solution would be to split up addresses using subdomains. That is, at the bottom line you have mail1.domain.com, and mail2.domain.com and divide the addresses among these. So you could have different users in the same TLD on different servers. It would probably be easy enough to set something up to route mail sent to [EMAIL PROTECTED] to the correct final destination so users wouldn't need to use [EMAIL PROTECTED] as their email address. -- Jamie Thursday, June 3, 2004, 11:31:30 AM, you wrote: DP Has anyone who is running vpopmail/qmail/mysqlcreated a DP backup/redundant or even a secondary server for the same domains?

RE: [vchkpw] RE: Redundant server
The reason why I asked about the script, is because backups are done by a different machine. And my apologies for sending an off topic message, but thank you for your reply you gave me a starting point. -Original Message- From: James Treworgy [mailto:[EMAIL PROTECTED] Sent: Thursday, June 03, 2004 11:26 AM To: David Petruzzella Cc: [EMAIL PROTECTED] Subject: Re: [vchkpw] RE: Redundant server This doesn't have anything to do with vpopmail.

Rsync these directories over to the other machine /var/qmail/control /var/qmail/users /home/vpopmail/domains Be sure to have rsync delete files that don't exist on the first machine. On the second machine don't use the virtualdomains file. Instead have an smtproutes file to forward everything over to the first machine. In case of a failure of the first machine: on the second machine put the virtualdomains file in place (from the first machine) and remove the smtproutes file. It is easier if you use cdb, but if you need to use mysql, setup mysql to replicate from the first machine to the second machine. I'd recommend turning off auth_logging if possible. That will signficantly reduce the replication traffic. If you have three machines use a standard cluster setup with the third machine as an NFS server mounting the /home/vpopmail/domains directory. Hope that helps, Ken Jones

Re: [vchkpw] RE: Redundant server
Well, i make a tar.gz file with the crontab of the /home/vpopmail, where the mailboxes are, but the only important thing is the file called "vpasswd", with this file you can make a cvs file like this one ./vadduser -q "quota" [EMAIL PROTECTED] password only with this information, imagine you have a larger file, for example more than 100 lines like this one, once you have created this file you only have to run it in the new server, with the vpopmail and qmail installed and it creates all the users again.
