Re: [qmailtoaster] disable mx check in chkuser
hello allo thanks to all for your help recompiling qmail-toaster*.src.rpm for making changes in chkuser my requirement was as such when my clients use webmail and send emails to say around 50 or 100 users and even if one of the recepients had a bad email id like a spelling mistake in their domain name or email formatting, then the entire email used to fail this was pretty annoying because the error message simply used to say : no valid mx or invalid format, without mentioning exactly which email id is at fault i would have preferred to remove mx checks and format checks on webmail ie disable only for those emails that originate from my server, but this is NOT POSSIBLE, i could only disable mx check / format checks for the entire server which is not what i wanted so the only solution i found was to enable #define CHKUSER_STARTING_VARIABLE CHKUSER_START and then recompile qmail toaster as per instructions given here http://wiki.qmailtoaster.org/index.php/Chkuser during the process is highly recommended that you keep the sleep time to around 10 or 15 mins ie 600 or 900 seconds so that you can relax and do what you need to do. important points when you do recompilation all folders under /var/qmail including the queue seems to have been modified. ensure that after you recompile, be sure to modify the tcp.smtp file and recompile the cdb as per new chkuser settings once again thanks to everybody rajesh On 04/06/2010 12:00 PM, Rajesh M wrote: thanks very much jake one very important point will this recompilation also reinstall / recreate the qmail queue which is the most scary part ? rajesh It should not wipe out the current queue, but you would want to stop inbound smtp services to allow the queue to clear out before performing this anyway, just to make sure you do not remove anything that you wish you had not. - Qmailtoaster is sponsored by Vickers Consulting Group (www.vickersconsulting.com) Vickers Consulting Group offers Qmailtoaster support and installations.

Re: [qmailtoaster] disable mx check in chkuser
I understand your point, but at some point they must take responsibility for using the service effectively. If removing CHKUSER compromises server security, which I believe it does I would find an alternative. Eric and Jake will likely have a better solution.

Re: [qmailtoaster] disable mx check in chkuser
The other way of looking at this problem is using an alternative SMTP server (smart host?). If you use the SMTP server (ISP's one) then all e-mails are accepted and after some time you have those e-mails which were mistyped bounced back. I find MX check very useful which saves my time if I have a typo in the email address. Also I would not disable Chkuser function.

[qmailtoaster] disable mx check in chkuser
hi i use squirrelmail when customers send emails to a number of people from webmail then if there is one address that is wrong the message that is shown is #5.1.1 chkuser - can't find valid MX for rcpt domain however the exact domain name where the problem exists is not shown here i see two ways out a) either i get the exact email id which has the problem, but i am not sure whether squirrelmail needs to be modified or chkuser --- this would be ideal. b) the easy way -- disable chkuser MX checks for webmail users so that the bad email id bounces back after some time. could you please guide me on how to do this ? thanks rajesh - Qmailtoaster is sponsored by Vickers Consulting Group (www.vickersconsulting.com) Vickers Consulting Group offers Qmailtoaster support and installations.

Re: [qmailtoaster] disable mx check in chkuser
Rajesh, Maybe your customers should be more careful entering the address they are sending to? You can't make everything stupid proof. I don't think you can disable CHKUSER nor do I think you'd want to. This occurs not only in Squirrelmail, but in Thunderbird and other e mail clients when the recipient is addressed incorrectly.

Dear Rajesh, Please refer to the url mentioned below to solve your problem: http://wiki.qmailtoaster.org/index.php/Chkuser Chkuser From QMail-Toaster chkuser configuration is not configurable on the fly. Configuration settings currently in use are documented at /var/qmail/doc/chkuser_settings.h. To tailor your chkuser settings, use the following procedure (provided by Nick): # rpm -Uvh qmail-toaster*.src.rpm # cd /usr/src/redhat/SPECS (assuming you are using CentOS 4) edit qmail-toaster.spec. find 'sleep 5' (should be line 606). change 5 to 300 (5 seconds to 300 seconds). save. # rpmbuild -bb --with cnt40 qmail-toaster.spec (use the appropriate --with value for your distro) When the build process pauses, open another terminal and edit /usr/src/redhat/BUILD/qmail-1.03/chkuser_settings.h to your liking. You have 5 minutes (or whatever you changed the sleep parameter to). Save your changes and wait for the 300 seconds to expire and watch it build. Search for #define CHKUSER_RCPT_MX(4th statement from below in the chkuser_settings.h file) Modify the line to comment it. Before change : #define CHKUSER_RCPT_MX After Change : /* #define CHKUSER_RCPT_MX */ Then save the file and let the rpm rebuild # cd ../RPMS/i386/ # qmailctl stop # rpm -Uvh --replacefiles --replacepkgs qmail-*.rpm # qmailctl start That's the procedure for now.
