Hello,
I'm trying to setup dovecot with sieve support in a way where all sieve scripts are precompiled. All sieve scripts are in /var/cache/sieve/.
I believe I discovered a bug here. I describe below how to reproduce it.
Dovecot and the user that deliver runs as do not have write permission in /var/cache/sieve/.
h01:/var/cache/sieve# ls -la total 16 drwxr-xr-x 2 ecp ecp 4096 Mar 31 21:32 . drwxr-xr-x 10 root root 4096 Mar 31 20:14 .. -rw-r--r-- 1 ecp ecp 88 Mar 31 21:32 mailtest1@domain.com.sieve -rw-r--r-- 1 ecp ecp 132 Mar 31 21:32 mailtest1@domain.com.sievec
When deliver runs it logs this error:
open(/var/cache/sieve/mailtest1@domain.com.sievec.tmp) failed: Permission denied
This indicates deliver tries to compile the script, even though the compiled version already is there.
To verify I tested another case. I make the compiled script immutable and I did a chmod 777 on /var/cache/sieve/. Then deliver logs this error:
rename(/var/cache/sieve/mailtest1@domain.com.sievec.tmp, /var/cache/sieve/mailtest1@domain.com.sievec) failed: Operation not permitted
And deliver created the file mailtest1@domain.com.sievec.tmp.
Some relevant pieces of my dovecot.conf:
protocol lda { mail_plugins = quota cmusieve ... }
plugin { sieve = /var/cache/sieve/%u.sieve }
Anyone can help me? Is this an error on my end, or really a bug?
