Recently was handed keys to a qmail toaster installation (1.03-1.3.20, on Centos4) and got hammered by a backscatter spam attack. Digging around, I discovered the system had been installed without the Chkuser feature.
I followed the procedures at http://wiki.qmailtoaster.com/index.php/Chkuser with no apparent issues. Today I find out that user email is bouncing (that is, it's accepted by the qmailtoaster, and then a second message is generated) with the error message "Sorry, no mailbox here by that name. (#5.1.1)" Note - Chkuser is functioning correctly - invalid email addresses are rejected during the SMTP transaction with (reason: 511 sorry, no mailbox here by that name (#5.1.1 - chkuser)) So, it looks like something in the local delivery mechanism is broken. Not that familiar with qmail, so I start looking for config files that control local delivery. /var/qmail/control/defaultdelivery seems like a good choice, since the rpm command apparently modified it to contain ./Maildir/ and we're trying to deliver to multiple domains in /var/vpopmail/domains. No sane looking value that I can think of to put in that file seems to work. None of the other .qmail files that exist seem to have been updated when I recompiled to enable Chkuser. Any suggestions appreciated. --Chris --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
