451 4.3.0 Temporary internal failure

[Nutsch]

Hi,

OS: Debian GNU/Linux 7

df -hT
Filesystem     Type      Size  Used Avail Use% Mounted on
/dev/vzfs      reiserfs   30G   12G   19G  38% /

/etc/fstab
proc  /proc       proc    defaults    0    0
none  /dev/pts    devpts  rw,gid=5,mode=620    0    0
none  /run/shm    tmpfs   defaults    0    0


If someone knows an option to change the tmp directory in dovecot.conf, 
it would be very helpful. I can't find it.
I can't increase the size of tmp, its not an partition and even my 
provider don't knows how it can be possible that the tmp directory is 
limited to 1 MB.

Regards
Noctua
