Up until now, I've never had any problems with qmail. Recently I
upgraded one of my servers to SunOS 5.7 from SunOS 5.5.1. After
upgrading, I restored my /var/qmail directory so the configuration
remained identical. However, I'm now getting sporadic bounces when
mail is sent to certain users. After much experimentation, I've found
that a message to a user will bounce if that user's home directory
isn't mounted. We use Solaris automount to map user home directories
to /home/$USER as we always have. If the user's home directory is
mounted, qmail will deliver the message fine, otherwise it will bounce
as if the user doesn't exist. This never happened under SunOS 5.5.1
so I'm stumped. I tried re-compiling and re-installing qmail-1.03,
but still have the same problem.
I'll illustrate all this with the example below:
First, I display the mounted filesystems, and as you can see, my home
directory is currently the only one which is mounted to /home/ since
I'm the only active user on the system.
Next, a test mail message sent to a user (melissa) who doesn't have a
mounted home directory bounces with a
"Sorry,_no_mailbox_here_by_that_name._(#5.1.1)/" error.
Then, when I generate some activity in ~melissa, the automounter
automatically mounts /opt/home/melissa to /home/melissa.
Now, a test message is delivered to melissa fine. Does anyone have
any ideas whats going on here? This is obviously a serious problem
since now only active users can receive mail.
