Re: smtp on a specific IP
Thanks to all that helped. After seeing what would be involved, I think I will just report from the log files. Thanks again.

Why should anyone care? For most of us the machine qmail runs on differs from the one the webserver runs on, so it's another IP anyways. Do accounting based on qmail's logfiles. > Is it physically possible to control the IP that qmail-remote uses to send > from? Well, you can patch qmail-remote of course. There's a patch floating around to let qmail-remote bind to ONE specific IP. If you still insist on your idea it may be possible to modify this one. But be warned: parsing the sender's address, getting the domaina nd looking up a IP for it adds a lot of cruft to the code.

Re: smtp on a specific IP
Thank you for correcting me on what is doing the sending. I still can't believe that after all this time, I am the only one that wants to control what ip a domain sends mail out on.

Re: smtp on a specific IP
I don't think that will help me yet (Maybe I am being really stupid or missing something) How does qmail know that mail that is from domain mail.domain1.com is to be delivered on IP xxx.xxx.xxx.xxx and that mail from mail.domain2.com is to be delivered using IP yyy.yyy.yyy.yyy. At the point that qmail is sending out mail via smtp it no longer knows what domain it is send out mail for does it? There has to be some kind of config file that tells qmail-smtpd what domains to send for. I would expect something like this would have to be done. A file called smtpddomain1 mail.domain1.com Another file called smtpdotherdomains mail.domain2.com mail.domain3.com ...etc (I know that the above doesn't exist - just dreaming) Another thought would be if I could use the domain name on the program line as below. (That would be a pain to have to add a new smtp file for every domain that I want to be unique) > #!/bin/sh > QMAILDUID=`id -u qmaild` > NOFILESGID=`id -g qmaild` > MAXSMTPD=`/bin/cat /var/qmail/control/concurrencyincoming` > exec /usr/local/bin/softlimit -m 200 /usr/local/bin/tcpserver \ > -vPHR -c "$MAXSMTPD" -x /var/qmail/cdb/smtp.cdb \ > -u "$QMAILDUID" -g "$NOFILESGID" mail.domain1.com smtp /var/qmail/bin/qmail-smtpd 2>&1 > ^^ > run file for mail2.example.com: > > #!/bin/sh > QMAILDUID=`id -u qmaild` > NOFILESGID=`id -g qmaild` > MAXSMTPD=`/bin/cat /var/qmail/control/concurrencyincoming` > exec /usr/local/bin/softlimit -m 200 /usr/local/bin/tcpserver \ > -vPHR -c "$MAXSMTPD" -x /var/qmail/cdb/smtp.cdb \ > -u "$QMAILDUID" -g "$NOFILESGID" mail.domain2.com smtp /var/qmail/bin/qmail-smtpd 2>&1 > ^^

I believe there are patches out there to allow more detailed logging, possibly also logging the mail size. I've followed this thread for a bit and if I understand correctly stock qmail doesn't have the ability to send mail out through a particular IP and making it do so is not trivial.

Karsten has supplied the correct answer above. When an address is supplied in place of the '0' option to tcpserver, that is the address that the child process binds to. You have no control whatsoever as to which IP is used to send outbound mail*. Simply run two qmail-smtpd's, one each bound to the two IPs in question. I think that to get what you seem to want, you may have to run a second copy of qmail -- if you simply run two different qmail-smtpds, both will use the same control files. Depends on why you want separate instances of qmail-smtpd. Examples: Where mail1.example.com is IP 192.168.0.1 and mail2.example.com is 172.16.0.1, with appropriate MX records: run file for mail1.example.com: #!/bin/sh QMAILDUID=`id -u qmaild` NOFILESGID=`id -g qmaild` MAXSMTPD=`/bin/cat /var/qmail/control/concurrencyincoming` exec /usr/local/bin/softlimit -m 200 /usr/local/bin/tcpserver \ -vPHR -c "$MAXSMTPD" -x /var/qmail/cdb/smtp.cdb \ -u "$QMAILDUID" -g "$NOFILESGID" 192.168.0.1 smtp /var/qmail/bin/qmail-smtpd 2>&1 run file for mail2.example.com: #!/bin/sh QMAILDUID=`id -u qmaild` NOFILESGID=`id -g qmaild` MAXSMTPD=`/bin/cat /var/qmail/control/concurrencyincoming` exec /usr/local/bin/softlimit -m 200 /usr/local/bin/tcpserver \ -vPHR -c "$MAXSMTPD" -x /var/qmail/cdb/smtp.cdb \ -u "$QMAILDUID" -g "$NOFILESGID" 172.16.0.1 smtp /var/qmail/bin/qmail-smtpd 2>&1 Note that your run file differs from mine, I simply mangled my own rather than hand-type one... If this is simply for traffic analysis purposes, this should do the trick... * Your operating system's routing table, or NAT method, or whatever, may provide you with a way to control which IP address is used to send outbound mail. IIRC, there are patches that force qmail to always send using a specified IP address. Stock qmail, in and of itself, provides no way to control the IP address used to send mail on, AFAIK. -- Greg White Those who make peaceful revolution impossible will make violent revolution inevitable. -- John F.

smtp on a specific IP
My server is running vpopmail. I also have Multiple IP address' aliased off of one network card. I can do traffic analysis through my router by IP address and this works fine for incoming mail. The problem that I have is the outgoing mail all is going out through one IP. I need to be able to charge my customers for traffic. Is there any way to make different domains send out on their own IP address? here is my smtpd run from the supervise directory /var/qmail/bin/qmail-smtpd 2>&1 env - PATH="/var/qmail/bin:/usr/local/bin" \ tcpserver -v -p -u vpopmail -g vchkpw 0 smtp /var/qmail/bin/qmail-smtpd 2>&1
