RE: 5.0 next to 4.10.x
I use a nfs server with 2 qmail box's using Maildir and vpopmail and I don't see any issues with too many directories, etc. What kind of performance issues are you seeing? --- Brad Dameron Network Account Executive TSCNet Inc. www.tscnet.com Silverdale, WA. 1-888-8TSCNET -Original Message- From: Lu [mailto:[EMAIL PROTECTED]] Sent: Thursday, November 08, 2001 12:05 PM To: [EMAIL PROTECTED] Subject: RE: 5.0 next to 4.10.x I appreciate everyone's feedback on this.

Hi [EMAIL PROTECTED]: I read vpopmail install guide, I need the "Matt Simersons tcpserver-mysql patch". Can you tell me where to download? Thank you a lot! Stone M.jNov 9,2001
Re: 5.0 next to 4.10.x
If a site ever did get to the point where one machine couldn't handle the disk/network I/O, you could easily split up each domains user dirs across 1(default) to 63 nodes. 0-9,A-Z,a-z. Ken Jones On Thu, 2001-11-08 at 21:11, Doug Clements wrote: This is offset by the risk of running non-redundant servers. We have a large NFS store running on FreeBSD (trying to get a Netapp). vpopmail provides a very effective directory structure which dynamically accounts for large amounts of domains and users. Also, with a dedicated NFS server, you can stuff it full of RAM and have it cache most directory accesses. This takes disk access load off the mail client. It also provides a central place to back everything up to. Back up one server, and one server only. If a node dies, you replace it. If the NFS server dies, replace it and restore a backup of data. We keep 2 IDE drives in the NFS server for rotating backups, so in a pinch, if the raid fails, we could mount a backup disk and be back online in minutes. Of course, with a clustered netapp solution, it makes things so much easier. They're kinda expensive, though. From the FreeBSD 4.4 release notes: A simple hash-based lookup optimization for large directories called dirhash has been added. Conditional on the UFS_DIRHASH kernel option, it improves the speed of operations on very large directories at the expense of some memory. So if you have tons of memory and still aren't happy with performance, you can tweak the server to be even faster :) --Doug -Original Message- From: Lu [mailto:[EMAIL PROTECTED]] Sent: Thursday, November 08, 2001 12:05 PM To: [EMAIL PROTECTED] Subject: RE: 5.0 next to 4.10.x I appreciate everyone's feedback on this.

Re: Restarting qmail-send in a cluster
I believe that this could be done with dsh (the distributed shell) too. http://packages.debian.org/testing/net/dsh.html It needs a remote shell like ssh and rsh though. Once install, just define the group of servers, i.e. clusters, and then when it is time to issue kill -HUP signal to qmail[-send], just issue the command: dsh -g clusters killall -HUP qmail-send or dsh -g clusters svc -h /service/qmail Hendry D. Lee Hey guys! I had a brainstorm the other night when I was talking with Ken. Why not use tcpserver as a wrapper to hup qmail-send on all the smtp boxes in a cluster? I've played with it, and it works. Here's how I did it: Standard disclaimer -- This works for me in a cluster of 7 Sun's, 3 of which handle SMTP, and the rest do POP and IMAP. No warranties, blah blah blah First, I'm running qmail under daemontools, so my restart script is designed around it, but any shell script will work... [...]
Re: Manually updating virtualdomain databases
A slick way is to rsync almost the whole /var/qmail/control and /var/qmail/users directories. You can skip the control/me file if you want each server to tag emails with thier id. As long as the OS's are the same then the all the files will be compatible.

I can copy over the rcpthosts, morercpthosts, virtualdomains, and assign files to the slave server, but I can't figure out how to rebuild the binary databases from these files. The /home/vpopmail directory is NFS mounted from a central place to provide access to all domains to all servers, but I do not want to NFS mount /var/qmail. If I replace these files, then add/delete a domain using the vpopmail tools on the slave machine, it appears to update the binary files correctly, but I would like to know the correct way to do this. Anyone have some ideas? --Doug
Re: Problems with Virtual IP domains and Courier-imap 1.3.11
The key lies in the courier-imap preauthvchkpw.c file in the authlib directory. Check if it is calling the vpopmail function parse_email() or vset_default_domain(). If it doesn't, I've got a copy that should have it. These are the functions that set get the ip -- domain mapping from vpopmail.

Problem: domains on their own IP's cannot authenticate with the domain extension on the user name Example: test.axess.com = 216.162.64.210, vimap -a 216.162.64.210 test.axess.com User: rickm can not authenticate via pop3, user [EMAIL PROTECTED] does without any problem. Courier running without -nodnslookup and I've even tried compiling authvchkpw and installing that in /usr/lib/courier/libexec/authlib and changing the pop3d config file to use that instead of authdaemon. Same results either way. If I was clear, let me know and I'll elaborate. Regards, Rick

Steve Fulton has talked about writing a patch for this, but it would be built into vadduser I think, rather than something qmailadmin specific. Might want to ask him directly about it. I could patch qmailadmin to do this pretty easily, actually, since most of the framework for domain defaults is already there. Maybe I'll have time to do that today... Ok, I've patched qmailadmin to support default_quota quota in .qmailadmin-limits. Works for me, but please test. I also undid the change to QA_PACKAGE and QA_VERSION, as autoconf breaks it. Compilation will fail if you ever run make distclean. I'm sure there's a better way to get rid of the compilation warnings on FreeBSD, this just isn't it. See INSTALL for info.

slen, scat, scopy
Hello! I am trying to compile qmailadmin but I can't get it to work. The build fails with messages like this one: alias.o: In function `delredirectnow': /home/brasse/qmailadmin-0.45/alias.c:587: undefined reference to `slen' /home/brasse/qmailadmin-0.45/alias.c:589: undefined reference to `scopy' /home/brasse/qmailadmin-0.45/alias.c:590: undefined reference to `scat' I am guessing that these functions are defined in libvpopmail. I am using vpopmail 5.0. Does anyone know if these funstions are still defined in that version? That's the only explanation I can find. The lib_deps and inc_deps files are in /home/vpopmail/etc. The contents of them looks like this: inc_deps: -I/home/vpopmail/include lib_deps: -L/home/vpopmail/lib -lvpopmail Any suggestions?
