Installing mini-qmail seems to require qmail ids contrary to documentation
According to Dan's page on mini-qmail http://cr.yp.to/qmail/mini.html, installing mini-qmail doesn't require qmail entries in /etc/passwd or /etc/group. So one should conceptually just have to unpack qmail-1.03.tar.gz, create /var/qmail and run make setup check However, on doing this this is the error message received ./load auto-gid substdio.a error.a str.a fs.a ( ./auto-uid auto_uida `head -1 conf-users` \ &&./auto-uid auto_uidd `head -2 conf-users | tail -1` \ &&./auto-uid auto_uidl `head -3 conf-users | tail -1` \ &&./auto-uid auto_uido `head -4 conf-users | tail -1` \ &&./auto-uid auto_uidp `head -5 conf-users | tail -1` \ &&./auto-uid auto_uidq `head -6 conf-users | tail -1` \ &&./auto-uid auto_uidr `head -7 conf-users | tail -1` \ &&./auto-uid auto_uids `head -8 conf-users | tail -1` \ &&./auto-gid auto_gidq `head -1 conf-groups` \ &&./auto-gid auto_gidn `head -2 conf-groups | tail -1` \ ) > auto_uids.c.tmp && mv auto_uids.c.tmp auto_uids.c fatal: unable to find user alias So, does the installation of mini-qmail require creating of user-ids for installation and then one can delete them subsequently -- Yusuf Goolamabbas [EMAIL PROTECTED]
Large todo slows down qmail-send
FreeBSD machine with the queue on a softupdate filesystem Hi, I have a todo directory which has approx 200K messages in it. This leads to congestion in qmail-send since todo processing takes up far too much time. It's a bit too late to install the big-todo patch (since I don't want to blow up the queue). Are there any other techniques to help speed up qmail-send. I have temporarily shutdown incoming mail to let the queue drain Is there a way to put a secondary installation of qmail to help process messages faster Regards, Yusuf -- Yusuf Goolamabbas [EMAIL PROTECTED]

That is true, However I changed the forwarding to another system which doesn't do resolveable name checks and yet the messages are continuing to go the old system. (I changed /var/qmail/alias/.qmail-postmaster) and restarted qmail. Is this appropiate ? What are the alternatives to clear these messages from the queue Also, Do people see the benifit in doing resolvable name checks. Doesn't it hurt in the above scenario Thanks, Yusuf
Recipient MTA is rejecting bounces
Hi, I have a qmail-1.03 machine saw in my queue a few bounces in them. Also, looking at my logs I saw the following message @40003905243f24daf1b4 delivery 34: deferral: Connected_to_204.68.180.50_but_sender_was_rejected./Remote_host_said:_451_<#@[]>..._unresolvable_host_name_[],_see_RFC_1123,_sections_5.2.2_and_5.2.18./ Is the recipient MTA correct in its behaviour or have I misconfigured something on my side Regards, Yusuf -- Yusuf Goolamabbas [EMAIL PROTECTED]
Converting a sendmail rule for anti spamming to Qmail
I came across this. Can I get similar functionality in Qmail. If so, how Comments on whether this is appropiate or not is also welcome http://www.harker.com/sendmail/local-msg-id-ruleset.html -- Yusuf Goolamabbas [EMAIL PROTECTED]
Will moving system time back lead to bad juju ?
Hi, One of my machines is out of sync by approx an 1.5 hrs (I thought there was ntpd running but it wasn't). It's ahead by 1.5 hrs This box runs a few moderated mailing lists and some unmoderated mailing lists. Thus the queue is not fairly full though there may be a a few messages in there due to remote hosts down or timeouts etc If I were to sync the clock via ntpdate/xntp. Will this lead to any bad juju. Under what conditions are time shifts acceptable/valid for qmail Regards, Yusuf -- Yusuf Goolamabbas [EMAIL PROTECTED]
Is it possible to route mail to /dev/null from .qmail files
Platform RH 6.0 with kernel 2.2.13 Hi, I just tried the following experiement in a .qmail-ext file which contains the following line /dev/null Sending email to user-ext@machine results in the following message in the log file deferral: Unable_to_write_/dev/null:_invalid_argument._(#4.3.0)/ However, the above scheme works on a FreeBsd box Anything I might have missed Regards, Yusuf -- Yusuf Goolamabbas [EMAIL PROTECTED]
Question on big-todo patch
Hi, My todo directory has grown to around 7000 files and I am considering using the big-todo patch. I have never used it Do I just stop qmail, apply the patch and reinstall or do I have to munge the queue. If I have to munge the queue, what is the magic incantation to keep exisiting messages safe Cheers, Yusuf -- Yusuf Goolamabbas [EMAIL PROTECTED]
Re: Is it possible to reject mail from sites with incorrect inverse DNS records
Thanks, for the info > However, note that in my experience i have not seen any adverse effects of > allowing connections from sites which have no PTR records. Why do you want > to reject these connections? Wouldn't spammers be likely to come from sites with such credentials, OTOH, It might affect people whose ISP's are unwilling/not clued in to set reverse maps for them Thanks, yusuf
Is it possible to reject mail from sites with incorrect inverse DNS records
Hi, I run a mail server with an upatched qmail-1.03 and tcpserver with rblsmtpd. Is it possible to reject mail from sites which don't have correct inverse DNS records (PTR records). If there is patch for qmail/tcpserver, would appreciate a pointer to it and a usage example Thanks, Yusuf [EMAIL PROTECTED]
Is there a similar feature to sendmail's 'access_db' macro ?
Hi, I want to setup a front-end which does spam-management to a set of
qmail boxes and I was wondering if there was a way to get a similar feature
as sendmail's FEATURE('access_db') which allows one to reject both senders/recipients
at the SMTP level
Thanks, Yusuf

Does Qmail have support for Dynamic IP Spam Sources List
Hi, The following web site http://www.imrss.org/dssl/ seems to have a mechanism to prevent spammers from sending directly from dial-up lines. The site has no docs on how to get qmail integrated with it, Anybody have any idea Thanks, Yusuf -- Yusuf Goolamabbas [EMAIL PROTECTED]
Should tcpserver block connections once conccurrency has been reached
Hi, I am currently using tcpserver on a Linux 2.0.36 box/RH 5.2 box I have setup tcpserver with a limit of 5 connections via -c5 and backlog of 1 with -b1 However, when I start up the 7th and subsequent connection, I basically get held up waiting for the smtpgreeting string which will occur as soon as I close some other connection. However with netstat -t I can see, that all the exisiting connections are in the ESTABLISHED state. If I were to increase concurrency limit to something higher, is there a possibility that the OS TCP tables might become full, with most entries primarily waiting for connections to complete. Would it be better to refuse connection ? In sendmail 8.9.3, using the following flags # maximum number of children we allow at one time O MaxDaemonChildren=4 # maximum number of new connections per second O ConnectionRateThrottle=3 If the sixth connection comes in, its is refused Is there a patch to tcpserver which does something similar or this concept/idea is bogus :-) Thanks, Yusuf -- Yusuf Goolamabbas [EMAIL PROTECTED]
How to slowly drain Maildir via maildirsmtp ?
Hi, I had setup a backup mailserver to collect incoming mail whilst my server was being upgraded. I used virtualdomains and put it all in a Maildir. Now that the server has been upgraded, I plan to use maildirsmtp to send the mail back out. However, I would like to not flood the remote machine and send some messages, wait for (a little while) the remote machine to clear its queue etc Appreciate any ideas Regards, Yusuf -- Yusuf Goolamabbas [EMAIL PROTECTED]
debbugs and qmail
Hi, I came across the Debian bug tracking system today http://www.chiark.greenend.org.uk/~ian/debbugs/ In the README file, it is mentioned as If the local MTA is qmail you _must_ install a different MTA somewhere (eg in a subdirectory) and tell the bug system to use that; qmail has broken command-line parsing in its /usr/lib/sendmail emulation. Has anybody used this package and can elaborate on what the author refers to as broken command-line parsing -- Yusuf Goolamabbas [EMAIL PROTECTED]
