Hi,

Please I have a question:

If my server is out of space (disk full) and the postfix is LDA, the new messages a deffered or refused,so postfix send 450 to sender ... But When I use dovecot (1.2.16) like LDA, postfix accept message (even there is no space), forward to dovecot, dovecot REFUSE the message and message is lost !

How can I solve this ? I don't want tu use quota and the disk was full, because of the other problem ....

This is more of a mail server admin 101 issue than a Dovecot issue. Putting your log, mail spool, and user mail directories on separate partitions, physical disks, or SAN LUNs will prevent such a problem from occurring 99% of the time, assuming you have planned and sized your storage appropriately for your environment. At minimum you should have your spool and user mail storage on different partitions. To avoid this issue the other 1% of the time, use monitoring or log summary tools to notify you of disk space usage so you know when you're close to running out of space. For instance, I receive the following as part of my daily logwatch summary on my personal domain MX:

Filesystem Size Used Avail Use% Mounted on /dev/sda2 33G 4.2G 28G 14% / /dev/sda1 92M 8.4M 79M 10% /boot /dev/sda6 94G 1.2G 92G 2% /home /dev/sda7 94G 25G 70G 26% /samba

Note that I have both system logs and the mail spool on / but user mail directories in /home. This setup is acceptable for a low volume server. For a high volume server the mail spool should be on a dedicated partition, as well as user mail dirs.

If you already know all of this and an unforeseen issue caused your problem, accept my apologies for preaching to the choir.
