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. Regards, Anil Aliyan ____________________________________________________________________________ ________________________________ 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.
