@Shane: I installed the latest version of vpopmail. I notice that your uid and gid match, whereas mine are not only not 89, they are also different from each other. As for the virtual domain thing, I'm not sure exactly what 'virtual domain' means in terms of qmail/vpopmail. My domain is a virtual host in Apache terms; it isn't the primary domain. Should I remove it from locals?
@James: I used 'find' to look for both tcp.smtp and tcp.smtp.cdb, and found only two: the one in /etc, and the one in /home/vpopmail/etc. None of them get updated when I authenticate. !DSPAM:4af9b81932712430412926!
