Re: Server cluster
On 99.12.27 Brian Grossman pressed the following keys: Once you get to a high volume of incoming mail, your first bottleneck will likely be the disk hosting /var/qmail/queue. If Linux is the preferred system for this cluster, than you can take a look at reiserfs: one of journaling filesystems that are being developped for Linux.

Re: Corel Linux ships with qmail installed, but not running
I installed Corel's Linux and there is a function in the xwindows client for starting q-mail. It will ask you the name of the server etc and install all existing users. It works great and is pretty hard to screw up. I am having one problem though. When handing off mail to the server from a POP3 client it can take up to a couple of minutes.

No. Qmail throws all the virtualdomain left-hand-sides into a hash, and it searches in a particular order: it searches for the entire address, then the entire domain name, then it strips off leading domains and searches until there is no more to strip off. The order in the original file doesn't matter unless you have identical left-hand-sides. -- -russ nelson [EMAIL PROTECTED] http://russnelson.com Crynwr sells support for free software | PGPok | "Ask not what your country 521 Pleasant Valley Rd. | +1 315 268 1925 voice | can force other people to Potsdam, NY 13676-3213 | +1 315 268 9201 FAX | do for you..." -Perry M.

Has anyone else experienced this or have any ideas on where I can look to track it down?

Re: Server cluster
This thread has raised some questions about NFS that I'd like to talk about since I'm looking at potentially using qmail with NFS to create an e-mail cluster. I'm looking at qmail because its maildir message store appears to be NFS safe. We're currently using Innosoft's SMTP and POP servers along with the Cyrus IMAP server on two independent machines. At one time, we had 6 independent servers, but we've consolidated into 2 to save $$$. It seemed too many costs were multiplied by the number of servers. And load balancing across so many independent servers was difficult for users. But now we've got too many eggs in too few baskets. We lost one of these servers for the better part of a day a few months back when a RAID 5 system failed and caught quite a bit of grief. A RAID controller failed and when the system attempted to roll over to the redundant controller, it hung and was corrupted. It took about 6 hours to get the system back online. I'm sure NFS has earned its reputation for unreliability, but I think there are a new generation of dedicated NFS appliances that deserve a second look. We've been using NetApp filers with our web and database servers and I've been pleased with the reliability and performance. I don't mean for this to be a pitch for NetApp. NetApp has several able competitors. NetApp is just the one we've chosen and where we have some experience. We use the NetApp filers as backend servers on a private gigabit LAN so security is manageable. The NetApp class of machine is designed for simplicity and reliability. Multiple hot-swappable power supplies and fans, hot-swappable disks, and you can buy a spares kit with the things that are most likely to fail, including the mother board. So if you have a hardware failure that brings the system down, you should be able to get back up quickly. You can "cluster" two NetApp's in a fully redundant system, but that was a little beyond our budget. We are looking at using their mirroring software to create a mirror of the e-mail volumes on the web filer. That way, if the e-mail filer failed and we couldn't get it back up quickly, we could mount the mirror volume from the web filer. My goal is to create a cluster that supports SMTP, POP, and IMAP. If one of the servers fails, existing connections might be broken, but the system should appear to heal itself quickly and, when users try again, it should appear fully functional. We'll do the load balancing with MX and Foundry Network's ServerIron layer 4 switches. Foundry also has a number of able competitors. To me, I want both the MTA (SMTP) and mailbox servers (POP/IMAP) to be clustered. I don't see a need to separate the MTA from the mailbox servers since they seem so interdependent. Actually, I worry a bit less about the MTA since SMTP is inherently store and forward and MX provides an easy way to load balance across multiple MTA's. I worry more about the mailbox servers. If it takes a little while longer for some messages to be delivered because of an MTA failure, users may not notice. If a mailbox server fails, users will know immediately. If that mailbox server is down for very long, users will be looking for scalps. So the scenario I'm looking at would look something like: ( public network ) | ++ | firewall + ++ | ++ | switch(es) | ++ | | ++ ++ | server 1 + | server 2 + (more servers, if needed) ++ ++ | | ++ | switch(es) | ++ | ++ | filer(s) | ++ Another thing I like about these filers is the ability to manage _storage_ separate from _servers_. Before, each server had its own storage subsystem that had to be managed separately. If one server was running low on space, it wasn't easy to move space from one server to another. With a filer, we can add disks as needed, on the fly in most cases, and the space is immediately available to all of the servers. It also makes backup easier. Not being familiar with qmail, the biggest question for me is if I'll be able to do all the things I'm doing now. For example, our current POP/IMAP servers don't allow plaintext login, but provide a number of options such as SSL, APOP, and CRAM-MD5. We also do SMTP AUTH with SSL and CRAM-MD5 authentication. And our SMTP server allows relaying if you authenticate. And we can automatically post messages to any IMAP mailbox. One thing we don't have at this point is a single, unified account database and message store for POP and IMAP. Cyrus could do this as will the next version of the

virtual domains in qmail/ezmlm?
Hi- I have finally mastered qmail (OK, "I installed qmail and it works") and am now trying to set up a couple ezmlm lists on a server with virtual domains. My /var/qmail/control/virtualdomains file looks like this: domain1.com:forwarder-domain1 domain2.com:forwarder-domain2 ... I obviously have a special user, "forwarder", set up with lots of .qmail files, and all is fine working for normal qmail traffic. I try making a list, [EMAIL PROTECTED]: ezmlm-make /virtual/domain1/ezmlm /home/forwarder/.qmail-domain1 domain1 domain1.com (that's one line, the dir is OK, and the links get created in /home/forwarder/) But I get: "Sorry, no mailbox here by that name. (#5.1.1)" when I try to talk to it. (mailing to [EMAIL PROTECTED]) I am trying to make simple, public lists for a couple of virtual domains. I think all I have to do is get the ezmlm-make command line right. Any help would be greatly appreciated! Thanks, Pete PS: Am I missing something, or are the only docs what comes in the .tar.gz?
