[vchkpw] Clustering
Hello list, Sorry if this is off Topic. I have a setup of qmail+vpopmail+sqwebmail+qmail-scanner+clamav+qmailadmin+vqadmin running on Redhat Fedora1 and am planning to go for Enterprise ES My question is how do I implement clustering solution for this setup? what is the required Hardware and Software for hosting 800 Domain with 80K mailbox. I did some search on google and I have found clustering solution offered by HP Proliant DL380 G3 Packaged Cluster and a solution offered by Netapp using their Filers ( F710 for example) which I have found it here on this mailing list. I also checked LVS and I have found someone with the same setup, who mentioned that there are some modifications to be made on the sources. Any one has experience on this would like to share it? Any links or docs about this setup? Any commercial support for such a setup, may be inter7 would give me a hint. Sorry for the long mail. Any help would be very much appreciated.

[vchkpw] Web lists archiving - part II
Hi, Ok, i can already browse the MLs archive. Problem is: i have more than one list, and it always shows the one from the line that is in the top: 0;510;/home/vpopmail/domains/netual.pt/intra;[EMAIL PROTECTED];[Home]=http://mail.netual.pt/cgi-bin/ezmlm-cgi/intra 0;510;/home/vpopmail/domains/netual.pt/dev;[EMAIL PROTECTED];[Home]=http://mail.netual.pt/cgi-bin/ezmlm-cgi/dev No matter what URL, i always get intra list, not dev also.

[vchkpw] Strange problem with SMTP AUTH
Hi! I have a really strange problem with vpopmail and smtp. I'm using qmail and vpopmail together and for pop3 and imap4 it works perfectly. However, with SMTP AUTH it did work well for some time but doesn't do so any more. As I didn't realize the problem at once, I actually can't say what exactly has changed on the system since it worked last. I'm running Gentoo Linux and there was at least one emerge -u world since it worked. I'm using Qmail+vpopmail+MySQL. So here's what happens: My client gives me an error but there's no error message from the server. If I look into the log files I find two interesting lines. Jul 14 12:23:27 myserver vpopmail[13453]: vchkpw-smtp: vpopmail user not found [EMAIL PROTECTED]:134.123.123.123 Jul 14 12:23:27 myserver vpopmail[13453]: vchkpw: can't write MySQL logs I've found out that if I change the permissions of /etc/vpopmail.conf to world-readability, I don't get the second line and the message is also written to my vlog-table. I guess it's only a subsequent error which I wouldn't get if the first one wasn't there. The first error message I don't understand at all because the user is valid. The same user can fetch mail without any problems. Can anybody tell me what is happening here? Is it a problem with permissions? If yes, permissions of what file?

Make sure your SMTP server is running as the vpopmail user. Make sure qmail-smtpd has the correct SMTP AUTH patch to match your vpopmail installation. At some point leading up to the 5.4 release, we fixed a bug in vchkpw related to CRAM-MD5 SMTP AUTH. But, you need to use the correct (bug-fixed) SMTP AUTH patch to qmail-smtpd to go with it. -- Tom Collins - [EMAIL PROTECTED] QmailAdmin: http://qmailadmin.sf.net/ Vpopmail: http://vpopmail.sf.net/ Info on the Sniffter hand-held Network Tester: http://sniffter.com/

Re: [vchkpw] Clustering
Well... i did some research for a proposed 120k maildirs on this setup, although with squirrelmail. Here are some big pointers: A) The bottleneck of smtp is the storage (good storage bandwith), since its such a simple protocol. Still, storage bandwith is the important thing in the whole analysis cause if thats slow (you generate more IOPS than what the storage can handle), everything will suck. B) The bulk processing youll need, will be generated by email analysis C) The second largest processing hog will be the webserver with the webmail cgi's The combo of this premises takes you down to this: 1) Take the average number of emails you think your users receive. 10-20 per day is a reasonable estimate for some uses (schools for example). Then also an average email size. Multiply one by another, youll get your kbps per mailbox. 2) Take into account if you are using pop or imap as the mailbox protocol. Imap will charge more IOPS in a first analysis, but over time, it actually takes less (cause users can delete email they dont want before reading it). Also, work into the model the usage pattern of your users... how about: 80% of the users check email from 9:00 to 9:30 AM. Youll be able to calculate the IOPS generated from such an ugly, although typical, peak. Also, mbox format will be easyer on the IOPS, but a lot tougher to the imap server. So, choose mbox vs maildir carefully. 3) As you want email analaysis (antispam, antiviri), youll want to calculate how many emails can that really deliver (you can say you receive 1 emails per second, but the virus/spam farm wont be able to actually deliver that many to the storage, unless you have an UberFast bunch of servers doing the analysis). Put all that into your opencalc, play with it, make a test farm, present to boss ask for a raiseget a denial... go look for another job...;-) Now...techietalkin about the techs for this: Id go for ldap/sql based user management (as your admin tools allow), consolidated, replicated storage (SAN, DRBD or GFS), LVS for the load balancing, the smaller protocol for internal email passing (i dont remember the name, its an much smaller, simpler, smtp lookalike that suits delivery between servers on a farm). I did some search on google and I have found clustering solution offered by HP Proliant DL380 G3 Packaged Cluster and a solution offered by Netapp using their Filers ( F710 for example) which I have found it here on this mailing list. I also checked LVS and I have found someone with the same setup, who mentioned that there are some modifications to be made on the sources.

Now, I'd like to do some kind of SMTP authetication using the idea of SMTPafterPOP, to use the vpopmail users (into vpasswd file) to authenticate the sending of emails. I found some patches for QMail, but I'm doubt about the functionality of its with vpopmail users database. I work in a school and there are other units of it that uses internet providers with dinamic IPs. Then, all the time I need to change /etc/tcp.smtp to add the actual IP address for the list of external users to do SMTP relay. But I think if I will have SMTP authentication, I may do a QMail OPEN RELAY and all will work fine. Is this TRUE or I'm CRAZY to think about OPEN RELAY? Is there some alternatives to do this without OPEN RELAY? Use tonix's qmail-smtp/vpopmail auth patch. Smtp authentication is the cleanest way to go. Ken Jones But, with it, I will configure /etc/tcp.smtp for 0.0.0. = OPEN RELAY? No. Just configure tcp.smtp for all static IP's you want to allow to relay without authentication, like internal servers that need an outbound mail server. For example: 127.0.0.1:allow,RELAYCLIENT= 209.218.8.:allow,RELAYCLIENT= Ken Hi, I installed the smtp-auth patch, the certificate was created fine, client Mozilla recognized this certificate, and sending/receiving emails from LAN worked fine, but LAN IP is into /etc/tcp.smtp. Then, it's not using authentication. When I tried to remove LAN from /etc/tcp.smtp, to test real authentication the first message error was: 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1) 553 no valid cert for gatewaying (#5.7.1) Then, I followed the link http://www.differentpla.net/node/view/170 where it's said to change the supervise/qmail-smtpd/run into user/group ID from QMail to VPopmail. After do this, the message error changed to the traditional: 553 sorry, that domain isn't in my list of allowed rcpthosts (#5.7.1) the error about gatewaying didn't occur more. What's the problem? Is it needed to execute the run script with VPopmail users/group? What about the first problem about gatewaying?
