dovecot - May 2008 - Sieve/Vacation

hi,

i'm using 1.1.rc5 but the same error occured with 1.0.13.

the dovecot package was installed on centos 5 with rpm's from atrpms. 
exim 4.69.

everything works fine except the vacation's from sieve. don't get me 
wrong, sieve works for everything, including mailforwards, or sorting in 
subfolders.

but when i have a vacation, the script is compiled, but it produces the 
following output:

sieve_execute_bytecode(/var/virtuser/test@<adomain>.sievec) failed


(the "<adomain>" is replaced with the real domain of the user).

i use virtual users in different domains. the sieve-scripts are 
generated by horde/ingo and stored via ftp in the "/var/virtuser" 
directory with the pattern "%u.sieve".

the "sievec" files are up-to-date, because:

a) i can delete the "sievec" files and they are regenerated
b) i can "sieved" them and get an disassembled output with the
vacation
rule inside

but when executing the script (when a mail arrives) the upper error is 
logged and no vacation is processed.

the same error occured with 1.0.13

thank you
</usc>

If Sieve's redirect is working, but vacation is not; I suspect, Dovecot 
Deliver can invoke sendmail to send mails. This was my problem some time 
ago.

With v1.1 there should be no problem with the missing Return-Path header, 
as well.

There was a post some time ago, which leads to think that there can be 
problems with UTF8 encodings. Did you tested vacation with a clean 7bit 
mail and vacation message? Also, did you stripped down the vacation 
directive to its minimum?

Did you already invoked deliver from command line? Sometimes there are 
hints:

Craft a valid message, then
su systemuser -c 'limit -c unlimited ; dovecot-deliver -f sender -d user
< msg'

If there is a problem sending the mail, it might be useful to know what 
deliver calls, e.g. run a kernel API trace, e.g. "strace" in Linux.

Bye,
