mailbox dir
i configured qmail succesfully but my problem is whenever i sent an email to one of the users where my qmail was install i cant find the mail. in sendmail i know it was var/spool/mail where can i check that in qmail?
Re: mailbox dir
What does your /var/qmail/control/defaultdelivery file say? The most probable location is /home/username/Mailbox or /home/username/Maildir/cur, new, tmp At 15:30 00/06/16 +0800, you wrote: > > > i configured qmail succesfully but my problem is whenever i sent an email > to one of the users where my qmail was install i cant find the mail. in > sendmail i know it was var/spool/mail where can i check that in qmail? >
Re: mailbox dir
You may try a 'ps -ef|grep qmail` and see if the appropriate qmail programs are running. Looking also at your log files may help in case there are errors. It is also important to note how you configured your qmail to deliver messages.

Re: mailbox dir
Remove the write permissions for group and others from the directory. Qmail is pretty strict on permissions.

Peter, Thank you for your response. This will come in handy.

secondry mail server setup
Hi there What is the best way to setup qmail as a secondary mail server for a domain name, ie something.com has 2 MX records, second MX points to a mail server running qmail. I need qmail to act as a fallback server, if the first (also qmail :) goes down or si busy. Whats the best way of doing this so that fallback will accept email and forward everything to a pop server. Also, whats the best way to tweak both servers so that the server one has a nice threashold, and the fallback handles anything above that threashold of incoming mail. thanks for any help nicholas --== Sent via Deja.com http://www.deja.com/ ==-- Before you buy.

This would probably be most useful on machines with more CPU than drive space. Mind you, drive space does tend to be cheaper these days than CPU time. I'd be interested in stats on storage difference of 1000 E-mails with and without the patch, as well as CPU time used with and without. I doubt anyone has time right now ... but.

It depends on your email traffic. A small company usually has a single box for web/ftp/mail/fax/dns and no more than 20 mails per hour. Nobody will notice the compression CPU overhead, but more disk space will be available. And yes, disks are cheap these days, but RAID makes them expensive. Best regards.

On the secondary server, put the domains for which you want to receive mail in rcpthosts, but not in locals or virtualdomains.

Limiting SMTP connections
For those who know the SMTP protocol better than I: If I limit my incoming SMTP connections on a box to something small, say 5, what does happens to further incomings; are they simply ignored, or NAK'd, or what? And on what % of servers out there will this mean that the message bounces entirely instead of being retried? Thanks. Side question: is there some way to get the stats (out of qmailanalog, etc.) as to how many simultaneous connections were happening on the various services at various times?

You might want to consider a two-staged mail system where the front/visible ones run your spam filtering and virus scanning and then forward to your backend systems that deliver to users mailboxes. Real virus scanning can be quite a resource intensive process as it has to crack open attachments, untar and unzip files searching for nested archives and so on. Consequently you may find that the system requirements for a front-end/virus/spam scanner are significantly different from a backend, mail delivery system. Regards.
Interesting disclosure of domains subscribed to qmail list
I know, I know, posting to both lists? But, tinydns made this easy and qmail is the list in question, so... I was just watching the tinydns logs when I mailed a message to the qmail mailing list. All of a sudden the query rate on my reply-address domain shot up as the log tail slid across the screen. It occurred to me that a lot of those queries are probably doing reverse lookups or anti-spam checks ensuring a valid reply domain. The reason I'm pointing this out is that I find it interesting that it indirectly exposes some domains which are likely to be subscribed to the list. Regards.
ucspi-ipc is now available
The message below went to [EMAIL PROTECTED] yesterday. A number of people I expected to see it evidently did not. Please pardon the scattershot approach. W. The ucspi-ipc-0.50 package is now available. Please see the ucspi-ipc home page: http://www.superscript.com/ucspi-ipc/intro.html ucspi-ipc is an UCSPI protocol for the local domain. It requires an implementation of getpeereid() to allow servers to obtain the credentials of clients that request connections. It includes tools similar to those in ucspi-tcp: ipcserver, ipcrules, ipcrulescheck, and ipcclient. Documentation is available via the ucspi-ipc home page. The current ucspi-ipc package includes implementations of getpeereid() for: * Linux kernels that support SO_PEERCRED with getsockopt(). * OpenBSD 2.6 with experimental extensions. I'll make the kernel modifications available as soon as possible. There is a mailing list for discussion of ucspi-ipc and other UCSPI protocols: [EMAIL PROTECTED] In a remarkable and amusing coincidence, Bruce Guenter released his ucspi-unix only yesterday. See http://em.ca/~bruceg/ucspi-unix/ While ucspi-unix and ucspi-ipc are similar in concept, the implementations are completely different. For example, ucspi-ipc is a djblib-based project; that is, it borrows heavily from actual DJB source code. Evidently, Bruce and I duplicated one another's efforts to some degree.

I'd guess that in this case, virus scanning may be the crippler. At 2.5 million per day, that's an *average* of 6 per second per machine to scan and deliver. Accounting for peak traffic periods, each machine could conceivably have to scan 30-60 messages per second to keep up with traffic. Depending on the virus scanner, that may (or may not) happen. You may want to consider dual-processor boards. It's much cheaper to build the box with BP6 motherboards and dual celerons than to put together two single-CPU machines. That way, you could at least have two virus scanning processes going in parallel. steve
Problems downloading via POP3
I just recently setup a qmail server with vpopmail as the virtual domain / pop manager. I'm encountering a problem though. Users with "large" messages >10K are having problems retrieving their messages. The clients start pulling the messages but get stuck and eventually timeout on these messages. I've checked tcpdump and I don't seem to be getting any activety from the server to the clients or clients to the server once they hit the messages. here's my pop3d supervise startup: #!/bin/sh service=pop3d .. /usr/lib/qmail/run-functions uid="`id -u vpopmail`" gid="`id -g vpopmail`" hostname="`hostname`" readdefault concurrency concurrencypop3d 20 readdefault checkpass checkpassword checkpassword do_ulimits exec tcpserver -u "$uid" -g "$gid" -c "$concurrency" -v -Hl -t5 -R -X \ -D -x /etc/tcpcontrol/pop3.cdb 0 pop-3 \ /var/qmail/bin/qmail-popup "$hostname" \ $checkpass \ qmail-pop3d Maildir/ This gives me a proccess executing as this: tcpserver -u 510 -g 502 -c 40 -v -Hl -t5 -R -X -D -x /etc/tcpcontrol/pop3.cdb 0 pop-3 /var/qmail/bin/qmail-popup mailbot /home/vpopmail/bin/vchkpw qmail-pop3d Maildir Any ideas what the solution is?

Re: Large Mail Cluster Questions
The original estimate was that this would be evenly split 50/50 in/out. But I don't believe this. Our marketing/sales guys are really pushing the volume up on the outbound side. And new services will be added... I don't think I'll get real numbers until it's too late. I'm looking for a scalable solution - but part of the scaling has to be able to allow me to adapt to a change quickly if I have to. If the numbers slide more toward outbound what kind of configuration change would I need??? >What is the estimated mail volume incoming?

NT / Qmail interoperation
Currently, we receive our incoming mail via NT Exchange server. We do not currently use our IBM RS6000 for any internet email purposes (ie, I am in unfamiliar territory with this project). Since our core business applications exist on the IBM system, I would like to develop the application that would form the email message, shell to AIX, and invoke Qmail which would then send the email to NT Exchange server. My reasons for this routing are: 1) There are security concerns governed by the network department over which I have no responsibility; 2) I don't want any email messages coming back to the RS6000. 3) Since I cannot influence the security policies, I want to transmit the email to a trusted source (Exchange) and let that source deal with the firewall, security issues, etc. Therefore, the RS6000 will only be sending email to the NT Exchange server. Hopefully, then, the NT Exchange server will then send out the email appropriately. I imagine someone is doing this and would appreciate constructive input. If you've got an installation similar to this and would like to correspond "offlist", please feel free to email me directly. Thanks. --robert [EMAIL PROTECTED]

Re: NT / Qmail interoperation
This is pretty trivial to do. All you need is a standard qmail install with a single entry in /var/qmail/control/smtproutes which points to your exchange server. That way all mail submitted to qmail will be forward via smtp to your exchange server. You may want to set concurrencyremote downwards to make life a little smoother for the NT server. Regards.

Kida hard to tell as it depends on how the outbound is submitted. But in general, a remote email consumes less system resources than a local email delivery. Regards.
Re: Password problems:
well, what i decided to do was switch to qpopper and use the --enable-home-dir-mail=Mailbox and it worked fine. now one thing that i don't understand is the rcpthosts file. it seems like it would be a file that would decide who gets to use qmail as the SMTP server, but when i try to send a message to somewhere like freak.net, it tells me that the address is not in the rcpthosts file. so is this to say where you can send to? do they have something for address that can use the SMTP server? are they one in the same? i put '.net' in the rcpthosts file and it sent fine. thanks, Z On Thu, 15 Jun 2000, Chris Johnson wrote: > On Thu, Jun 15, 2000 at 04:50:37PM -0500, Z wrote: > > From what I've heard many MUA's don't handle the maildir > > very easily. > > MUAs like mutt, and I believe recent versions of Pine (and if not there are > patches to make Pine understand maildirs), handle maildirs just fine.

Help with startup Script
Hi everyone, first I am new to qmail and I am using qmail with vpopmail and mysql support. I have several questions: Using the startup-scripts from www.inter7.com plus the startup scripts from My Life with qmail (of course I have adjusted the scripts from life with qmail to the needs of vpopmail as suggested by the authors) leads into an endless loop of tcpserver fatal error: unable to bind address messages. Where is my mistake? Scripts are posted at the end of the mail... Question 2: How does vpopmail put the mail? If there are no user accounts right? if you want to have ./Maildir/ support do you have to setup homedirs for every popaccount? what about dups? Question 3: Is there a qmail-pop3d hack out there which supports ./Mailbox formats and vchkpw? now to my scripts... /sbin/init.d/qmail... #!/bin/sh PATH=/var/qmail/bin:/usr/local/bin:/usr/bin:/bin export PATH case "$1" in start) echo -n "Starting qmail: svscan" cd /var/qmail/supervise env - PATH="$PATH" svscan & echo $! > /var/run/svscan.pid echo "." ;; stop) echo -n "Stopping qmail: svscan" kill cat /var/run/svscan.pidecho -n " qmail" svc -dx /var/qmail/supervise/* echo -n " logging" svc -dx /var/qmail/supervise/*/log echo "." ;; stat) cd /var/qmail/supervise svstat * */log ;; doqueue|alrm) echo "Sending ALRM signal to qmail-send." svc -a /var/qmail/supervise/qmail-send ;; queue) qmail-qstat qmail-qread ;; reload|hup) echo "Sending HUP signal to qmail-send." svc -h /var/qmail/supervise/qmail-send ;; pause) echo "Pausing qmail-send" svc -p /var/qmail/supervise/qmail-send echo "Pausing qmail-smtpd" svc -p /var/qmail/supervise/qmail-smtpd ;; cont) echo "Continuing qmail-send" svc -c /var/qmail/supervise/qmail-send echo "Continuing qmail-smtpd" svc -c /var/qmail/supervise/qmail-smtpd ;; restart) echo "Restarting qmail:" echo "* Stopping qmail-smtpd." svc -d /var/qmail/supervise/qmail-smtpd echo "* Sending qmail-send SIGTERM and restarting." svc -t /var/qmail/supervise/qmail-send echo "* Restarting qmail-smtpd." svc -u /var/qmail/supervise/qmail-smtpd ;; cdb) tcprules /etc/tcp.smtp.cdb /etc/tcp.smtp.tmp < /etc/tcp.smtp chmod 644 /etc/tcp.smtp* echo "Reloaded /etc/tcp.smtp." ;; help) cat <&1 env - PATH="/var/qmail/bin:/usr/local/bin" \ tcpserver -H -R -x /etc/tcp.smtp.cdb -c20 -u 507 -g101 0 smtp \ /var/qmail/bin/qmail-smtpd 2>&1 > /dev/null & #!/bin/sh exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t /var/log/qmail/smtpd - /var/qmail/supervise/qmail-pop3d/run ... and log/run ... #!/bin/sh env - PATH="/var/qmail/bin:/usr/local/bin" \ tcpserver 0 pop3 /var/qmail/bin/qmail-popup mail.byteaction.de \ /var/qmail/vpopmail/bin/vchkpw /var/qmail/bin/qmail-pop3d Maildir & #!/bin/sh exec /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog t /var/log/qmail/pop3d - Any Help from the pros is highly appreciated kind regards Juergen Hoffmann
Ascii art summary
I am new to this list having just about set up qmail on a home network linux server for the first time. I spent hours over a number of days pouring through the documentation and the qmail.org web site looking for help - and whilst I think I now have a picture NOWHERE could I find a summary of what all the control files did and in what order so that I could actually get qmail do what I wanted it to. There were plenty of simple guides if you wanted to set it up one particular way, but none of them were quite how I wanted it. Eventually, in order to understand I drew a flow chart, see below, to try and help my understand the process. Somewhat nervously I post it here (nervous because netiquette normally dictates that you lurk for while - I just was so desparate for this info that I felt it was worth the risk of making a complete plonker of myself) for two purposes. 1) To get verification that what I have summised is correct, AND 2) If we can get it correct to plead for someone to put it in a prominent place (like off www.qmail.org ) so that newcomers who come after me have a model to work with. -- 'me' can be used as default for a number of files do a 'man qmail-control' to get a list user = login account on system mail is being sent to [EMAIL PROTECTED] and can enter in two ways qmail-inject qmail-smtpd | (use smtpgreeting) | | "from"[EMAIL PROTECTED] is RELAYCLIENT defined?-Y-+ or [EMAIL PROTECTED]|| | N| | || | REJECT MAIL--N-is y.z in 'rcpthosts'| | || | Y| | || | V| +--++ | set "deliverto" = [EMAIL PROTECTED] | +->| | | | V | qmail-queue | | | | | qmail-send | | | if "from" has no @ use 'envnoathost' | | | is y.z in 'locals'-Y-+ | | | | N set "account" = x | | | |is any of [EMAIL PROTECTED] in 'virtualdomains' | || || |N Y| || || | qmail-rspawnlookup "account" (see below) | || add -x to end of | | qmail-remote "account" | || || | is y.z in 'smtproute' +--->| || | | |N Y qmail-lspawn || | | | lookup MX for y.z | | | and sendlookup route | |and sendis any of "account" | +-N-in 'users/assign' | | | | set "user" = Y |part of "account" before '-'| | |lookup "user" | | | | |<+ | | |is "user" qmailable (not root etc) | || | NY | || | set "user" = alias| | || | |<---+ |

What should that be good for?

Nope, not necessarily domains but mailservers handling mail traffic for users in domains subscribed to the list. But nevertheless these mail servers are IMHO broken. As ezmlm replaces the original Sender information with e.g. [EMAIL PROTECTED] the only domain that should get DNS queries on rcpt of the message should be list.cr.yp.to to verify a valid bounce host and probably the host serving the RDNS space of the mailserver sending out the list mails.

There is a patch for qmail-smtpd.c floating around (sorry, I don't
have it handy, and I can't extract one as my qmail-smtpd is *heavily*
patched) that basically checks for a environment variable
BOUNCEMAIL and if set sends back the contents of this variable in
smtp_rcpt() before the "250 ok".
As a way to go modify qmail-smtpd.c
near "char *relayclient;" add a line
char *bouncemail;
near "void err_bmf() { ... }" add a line
void err_bouncemail(s) char *s; { out(s); out(" (#5.7.1)\r\n"); }
in setup() before "dohelo()" add a line
bouncemail = env_get("BOUNCEMAIL");
in smtp_rcpt() after "if (flagbarf) { ...}" add a line
if (bouncemail) { err_bouncemail(bouncemail); return; }
This allows using tcprules like:
216.65.1.3:allow,BOUNCEMAIL="521 we do not accept messages from this server"
Please note, that this will not only filter out messages to one of your
client, but affects your qmail system as a whole. It will reject all
messages from 216.65.1.3 (i.e. exposed.freewebsites.com).
If you want the filtering to be client specific the solution depends
on how your client gets his email delivered.
