Qmail and its parts.
I don't normally ask for help, but this thing (qmail and associated programs) is driving me nuts. Environment and background: O/S: RedHat 7.0 compiled and installed these packages: qmail-1.03+patches-18 supervise-scripts-3.3-1 ucspi-tcp-0.88-1 ucspi-unix-0.34-1 vmailmgr-0.96.9-2 vmailmgr-courier-imap-0.96.9-2 vmailmgr-daemon-0.96.9-2 While I thought I've configured everything according to the million man files...mail comes in, gets put into a directory under /var/qmail/queue ps -ef | grep qmail reveals: root 198 194 0 08:59 ? 00:00:00 supervise qmailqmaild 570 1 0 09:00 ? 00:00:00 tcpserver -c 100 -u 101 -g 102 0 so qmail is apparantly running. qmail-showctl looks good. my rcpthosts contains the name of the mailserver, the name of the domain. virtualdomains looks good.. for both users i have defined right now, it has the name of the domain and the username (domainname:username). /etc/qmail/users/assign formatted according to the man page. qmail-qstat reveals: messages in queue: 24messages in queue but not yet preprocessed: 14 It would help me greatly if anyone could help me understand how all these things fit together. I know supervise is a replacement for just putting something in rc.d or whatever, and i think i have that running right, since qmail is running.What I'mhoping to accomplish is the delivery ofthe email into the correct user's maildir. Confused as to how vmailmgr fits into this, i've even made the .qmail file in the user's directory simply point at the maildir directory, instead of using the | to send the mail to the vmailmgr. Could someone get me started? Thanks.. Carl Danowski

imap response problem
Hi, I have a problem when I try to forward mails from my back up qmail server to MS Exchange server. that is if there are more than one mail in the queue that qmail try to flush out, qmail can only get one "/Remote host say 250ok " response with all mails go through( i got all mails). So it can only clean one mail out the queue but keep all the others and never try redeliver till i restart qmail, it resend all remaining mails get another 250ok ande remove another message from queue. 250ok appears randomly not always the first message that been delivered. May someone help me that what may cause this problem? Thanks for your help MinF
Re: Problems using qmail on very large site
Hi Mark, They stay running forever and the parent process is qmail-queue. Now I have 162 defunct process. Today I will try to alter rlim_fd_cur to 64 (the number of file descriptors - Today the value is 1024. 64 was the original value) and keep the rlim_fd_max to 2048, like it is today and I will reboot the machines. I read somewhere that isn't a good idea change the default current limit of file descriptors like I did. They suggest only change the max number of file descriptor. Well, is just a guess, but I think that won't cause any damage to try ;-) Thanks for your attention ! Regards. The problem is the fact that I'm having too much defunct process. Usually I have between 350-500 process running by machine. From that, normally I have between 90-120 defunct process per machine. Do they stay forever, or do they go away? Which qmail process is the parent? I have seen Solaris 2.x systems where processes do stay around forever, but I have not seen in on, eg, FreeBSD. Regards.
Re: Problems using qmail on very large site
Yuan, For change the current and max number of file descriptors in Solaris 2.6 (in 2.7 I think is the same but I'm not sure), you need add two entries in your /etc/system file: set rlim_fd_cur=1024 set rlim_fd_max=2048 and you MUST reboot your machine in order to changes take effect. To see if everythings works, try to use the command ulimit -a before and after the modifications. Unfortanately the max number of file descriptors wouldn't be showed, just the current will (open files parameter). Hope this helps. Regards, Claudio Hi, Excuse me for asking a silly question. In Solaris 2.6 or 2.7, how do you change rlim_fd_max etc? I cannot find it in the Answer Books. Thank you very much. Yuan Hi Mark, They stay running forever and the parent process is qmail-queue.

Re: Problems using qmail on very large site
Yuan, In my case, I changed both (rlim_fd_max and rlim_fd_cur to 2048 and 1024 respectively). After reboot my machines I don't received more messages like that. By the way, my concurrency remote is set to 255. So, I believe that for your case (50) this set (2048) should work fine too. I suggest that you try change just the rlim_fd_max, because I think that change rlim_fd_cur is unnecessary or, even (I still couldn't try decrease it like I said that I will), cause that problem that originate all this discussion: a lot of defunct process running in my machine ! But in my case, like I said, I'm using Solaris 2.6 and not 2.7 like you Regards, Claudio Is this caused by rlim_fd_max too small? Sincerely, Yuan Yuan, For change the current and max number of file descriptors in Solaris 2.6 (in 2.7 I think is the same but I'm not sure), you need add two entries in your /etc/system file: set rlim_fd_cur=1024 set rlim_fd_max=2048 and you MUST reboot your machine in order to changes take effect.

Problems using qmail on very large site
Hi everybody, I installed qmail (v. 1.03 running on Solaris 2.6 for x86 - JUST ! (without any patches)) with tcpwrapper ucspi-0.88 and multilog from daemontools package (v. 0.70) all them compiled with gcc 2.95.2 running in 4 machines PIII - 500Mhz with 256mb RAM. In my DNS I have smtp.ig.com.br pointing to IPs addresses of that four machines trying to make some kind of load balance (Probably soon I will replace this by IPVS or something like that (Altheon, etc). The total amount of messages that are sent through those machines are aprox. 1.5 million by day (!) . I have set remote and local concurrency to 255 (and I change the limit in conf-spawn to 255 and recompiled qmail after that). My tcpwrapper is configured to 400 simultaneous smtp connections (per machine). The remote and localconcurrency stay between 30-150 connections so, I think that 255 limit isn't problem by now (Maybe in future I will need to install the patch to concurrency above 400). Memory and wait I/O isn't the problem. The number of file descriptors are ok (2048) now (Now I don't receive messages tell me that was not possible to open a pipe (or something like that)). The problem is the fact that I'm having too much defunct process. Usually I have between 350-500 process running by machine. From that, normally I have between 90-120 defunct process per machine. Anybody have ANY idea about what can be causing this ? Is there any patch to correct this problem, in case of this be a well know problem for my plataform ? PS. multilog and tcpwrapper are in PATH and this problem NOT started after I reboot my machines ;-) Any help will be very appreciated . Thanks in advance...

Strange Problems whith starting qmail
Hi, although I'm almost expect my problem not having to do with qmail at all it happens to me while I try to start qmail only. Maybe you can give me a hint whats wrong. Whenever I try to start qmail via /var/qmail/rc qmail doesn't seem to start. /var/qmail/rc is a copy from /var/qmail/boot/home Using the "nohup" command in the rc-script as LWQ tells I get the following output in nohup.out: /usr/bin/nice: exec: No such file or directory # bash --version bash --version GNU bash, version 2.03.0(1)-release (i386-suse-linux) Copyright 1998 Free Software Foundation, Inc. # sh --version GNU bash, version 2.03.0(1)-release (i386-suse-linux) Copyright 1998 Free Software Foundation, Inc. I compiled qmail via make make setup check ./config-fast wotan.arc (I just want to use it inhouse) Any help would be appreciated. Thanks, Cyril Bitterich

Disconnected Operation
Hello everyone, I've got a mail server on a private network (192.168.x.x) which I want to periodically pick up mail from my server that's co-located elsewhere. Both servers are running qmail. The public server has MX records for my domain, pointing to it. Mail to/from there seems to be working just fine. I want the private server to periodically dialin, pick up the messages, send any that are queued (this is already working), and deliver via POP (also already working). SO, do I switch the public server from handling the mail as a standard domain to a virtual domain? How do I get the private server (which has a DYNAMIC IP address) to pickup the mail? I've looked at both fetchmail and serialmail. I think I understand how to do this with fetchmail, but I cannot make heads or tails of the serialmail "docs". Any advice, suggestions, etc? Thanks in advance, -Scott
Modifying tcpserver and checkpoppasswd
Just a little query... I'm currently using a slightly modified version of the Jedi/Sector One, Paul Gregg checkpoppasswd program and now I've modified it to use the DENY environ- ment variable. Rather than have ":deny" be the last line in my /etc/tcprules.d/ qmail-pop3d file, I replace it with ":allow,DENY=""" and that way I get the person to type in the username and password of the account they're trying to access and yet still guarantee that I can cut them off based on the existence of the DENY variable. My only problem now is that if they are trying to hack my server, they might not give a valid username or password. This is handled in the J/SO, PG checkpoppasswd in the newgetpwnam() function, which has no knowledge of the password variable as it is obtained from qmail-popup. So when an invalid username is used during a connection from a disallowed address, there's no way to log the password along side it. The cheap way around this is to just make "char *password" a global. Anyone foresee any problem with this? Second, when ":deny" is used, the originating port on the remote host is logged in the qmail-pop3d logfile. When ":allow,DENY=""" is used, that information is not passed along. I'd like to get my hands on a copy of the tcpserver source to add the TCPREMOTEPORT variable to the environemnt created by tcpserver. So, 1) Where can I find the sources. (I know, I know, STFW) 2) Anyone foresee any problem with this? 3) Would the author perhaps be so kind as to add it himself? I've also written several scripts and proggies of my own to centralize the operations of my ISP with SMTP, POP3, and RADIUS servers all maintaining consistency (of tapioca). I'll eventually be putting all of it under GPL and tarballing it onto my ftp site for all to gawk at. -- Matt Garrett, Network Engineer InterNIC handle: MG14026 Superior On-Line Services, LLC [EMAIL PROTECTED]

More than 2 queues ?
I know, asked that before, but here I go again: I was wondering - did anyone ever look into the creation of a third (or even more) delivery queues for qmail? Here is what I have in mind: local - for local addresses, aliases etc. remote - anything outside the local (mail) domain, subnet, whatever ... lan- any host inside the local (mail) domain, subnet, whatever ... ... It should be pretty straight forward in qmail-queue.c, and basically a modified copy of qmail-remote.c (plus a few setup changes). And to expand on that theme - maybe even something like a priority scheme? --__ __ - ' / '/ ) Thomas Bullinger / /-- This is the mail account for [EMAIL PROTECTED] (_/ /___/ http://www.btoy1.rochester.ny.us

Virtual Domain/Users not working proeprly
Hi, This is what we want to archive: [EMAIL PROTECTED] localuser1 [EMAIL PROTECTED] localuser2 [EMAIL PROTECTED] [EMAIL PROTECTED] @virtual.comanotherlocaluser How do we go about this i've added the domain virtual.com to rcpthosts, locals but how do you do the rest. I have read every peace of documenation i can find on qmail and it does not explain it anywhere. I've tried a number of things, so far over 150 email domains are down till i can fix this so if anyone has any ideas it would be appriated. Regards, Chris
