| My mail server has been periodically rejecting mail with the following
| error [logs from sending mail-relay]:
|
| 2004-12-20 18:07:49.596345500 delivery 12914: deferral:

|
| My logs report:
|
| Dec 20 18:15:29 rosewood sendmail[20639]: iBKNFTDN020639: low on space
| (SMTP-DAEMON needs 1451858 bytes + 100 blocks in /var/spool/mqueue), max
| avail: 0
|
| My disk usage looks like:
|
| Filesystem            Size  Used Avail Use% Mounted on
| /dev/hda2             572M  375M  168M  70% /
| /dev/hda1             122M   24M   92M  21% /boot
| /dev/hda3             5.4G  2.1G  3.1G  41% /home
| none                  496M     0  496M   0% /dev/shm
| /dev/hda7              28G   15G   12G  56% /usr
| /dev/hda5             2.0G  1.8G  101M  95% /var
|
| So, it is obvious I have a disk space issue in my /var partition.
| Someone on the list recently suggested copying my /var/mail directories
| to say my /usr partition and then symlinking to it from /var. Any
| thoughts on the viability of this? Also, when I first built this
| machine, I had not anticipated using MailScanner and Spamassassin and
| mail quarantines etc, so what do most of you assign for a partition size
| to /var when you are building your machines?
|
| I greatly appreciate any help anyone has to offer on this as I have some
| very agitated clients.
Try df -i and check for inode problems. I had this awhile back with a
LOT of 0 length log files from a bad samba log rotate.
