heya,
i've got the postfix-2.2.5p0-sasl2 port on an openbsd 3.7-stable machine. the
setup has been working great thus far, but now that i'm trying to encrypt my
virtual mailbox directory (using vnconfig) i'm encountering problems that i
can't resolve myself.
i have everything working fine without encrypted mailboxes: virtual mailboxes
setup such that all the email is delivered to subdirectories of /var/vmail,
where vmail is the virtual mailbox user account, and users can relay mail and
use IMAPS for access. on a few other openbsd machines i've successfully setup
encrypted disk images using vnconfig from whence i host FTP and samba shares.
there is no problem using these images that are mounted via vnconfig: the FTP
and samba servers access the mounted svnd devices without event. however, when i
attempt to mount an encrypted image on /var/vmail and use that image to store my
mailboxes, i get errors from postfix when it attempts delivery to one of the
virtual mailboxes. in terms of commands, i issue and see the following (this
includes some config file contents too):
$ cat /etc/fstab
/dev/wd0a / ffs rw 1 1
/dev/wd0h /home ffs rw,nodev,nosuid 1 2
/dev/wd0d /tmp ffs rw,nodev,nosuid 1 2
/dev/wd0g /usr ffs rw,nodev 1 2
/dev/wd0e /var ffs rw,nodev,nosuid 1 2
# this is the encrypted image: it's ~2GB
$ pwd
/home
$ ls -al protected
-rw-r--r-- 1 root wheel 2048000000 Jan 13 11:26 protected
# so i do the following
sudo postfix stop
sudo /usr/local/libexec/imapd-ssl.rc stop
sudo mv /var/vmail /var/vmail.bak
sudo vnconfig -ck -v /dev/svnd0c /home/protected
sudo mount -o rw,nodev,nosuid /dev/svnd0c /var/vmail
# i have tried mounting without any options and that doesn't work either
sudo cp -pR /var/vmail.bak/* /var/vmail/
$ df -h

i've tried adding the following to my /etc/postfix/main.cf to no avail:
message_size_limit = 52428800
virtual_mailbox_limit = 52428800
this happens with all message deliveries that are attempted. this particular
test email is more or less empty (< 2 KB).
one thought is that i can't mount something on a /var subdirectory that's larger
than the amount of free space on the /var partition itself. i haven't tested
this yet, but i don't suspect that this is the case. if it is, please apply the
cluestick. if there is anything i've left out in terms of information that would
be useful to help fix the problem, please let me know.
if this mail doesn't bounce from the postfix-users list, please make sure to CC
me on any reply since i'm not subscribed.
any suggestions welcome. thx for reading.
kind regards,
jake
