[vchkpw] debugging vchkpw?
I have a vpopmail server that's been running fine for over a year. Now, it's refusing to authenticate people; [EMAIL PROTECTED] tmp]# telnet localhost 110 Trying 127.0.0.1... Connected to localhost.

It's only for talking with qmail-popup and qmail-pop3d.\n); But I'm out of ideas as to what could have gone wrong. Curiously, courier-imap, is authenticating the same users fine. John

Re: [vchkpw] debugging vchkpw?
No, I'm a fool. I had a typo in the password I'd fed to vchkpw on the command line. I re-did it with the write password (again, the chdir works) but toward the end is; 25765 munmap(0x40015000, 4096) = 0 25765 time(NULL)= 1061373355 25765 open(/hsphere/local/var/vpopmail/etc/open-smtp.lock, O_RDWR|O_CREAT|O_TRUNC, 0666) = 4 25765 fcntl64(4, F_SETLK, {type=F_WRLCK, whence=SEEK_SET, start=0, len=0}) = 0 25765 open(/hsphere/local/var/vpopmail/etc/open-smtp, O_RDWR) = 5 25765 getpid() = 25765 25765 open(/hsphere/local/var/vpopmail/etc/open-smtp.tmp.25765, O_RDWR|O_CREAT|O_TRUNC, 0666) = 6 25765 fcntl64(4, F_SETLK, {type=F_UNLCK, whence=SEEK_SET, start=0, len=0}) = 0 25765 close(4) = 0 25765 getuid32()= 0 So, it looks like that's working logging in fine, even updating the pop before smtp database. Ominously, there is a file fix.sh in the vpopmail server I've never considered before, which may be a remnant of a previous sysadmin. Is this a standard tool ? John

I should have pointed out, You primarilly should have pointed out the relevant parts from strace log. 'open-stmp' is irrelevant if you're searching for a problem related to the users Maildir. Nevertheless: that although running vchkpw from the command line works fine, it still gives; -ERR this user has no $HOME/Maildir What makes you think vchkpw gives this error? In fact it is qmail-pop3d that does. Check the qmail-pop3d invokation line. It has to be qmail-popup HOSTNAME!!! Password-Checker qmail-pop3d maildirname Additionally try this: printf [EMAIL PROTECTED] | \ ~vpopmail/bin/vchkpw \ /bin/sh -c 'id; echo; stat $HOME/Maildir' 30 and see if the UID given by 'id' command has correct permissions to '$HOME/Maildir'. Is there a next step in debugging vpopmail you could recommend ? Yes. Beside the steps above that give some information I'd sit down an hour or two and heavily think about what has changed on the system. You wrote: I have a vpopmail server that's been running fine for over a year. Now, it's refusing to authenticate people; And this gives exactly /ONE/ conclusion: something was changed. Else behavior wouldn't have. I've quickly searched qmail sources and there are /EXACTLY/ two conditions when this error is triggered: 1.) No 'Maildir/' (or other directory name) at the end of qmail-pop3d invocation 2.) No permissions to 'chdir' to this given directory. -- Ciao, Pit

Some specific questions...first, I'm already using some .qmail files successfully (.qmail-default, .qmail-user for mailing lists or forwards). The configure help says the address extensions support is disabled by default (at least in 5.3.24). With it disabled, will this completely hose-up my current .qmail files? Where I am apparently having trouble is with .qmail files setup with forwards, etc., in user's home directories (same level as Maildir). For instance, /home/vpopmail/domains/domain.com/user/.qmail and /home/vpopmail/domains/domain.com/user/Maildir are at the same level. Would enabling these extensions then allow me to make use of that .qmail file? Or is this something completely different? Thanks!

Note that you could still override fred-something with a .qmail-fred-something in the domain directory. I think with extensions disabled, fred-something would be treated as another email address - so if you had the catchall set to bounce and no user named 'fred-something', then a fred-something email would bounce.
