[Dovecot] sieve-test issue

[Ian P. Christian]

Hi all,

I'm using a build of dovecot 1.2, and I'm seeing this:

# ls -al 1235038385.M765212P13483.tch-mailstore1\,S\=3927\,W\=4017\:2\,S
-rw------- 1 mail mail 3927 2009-02-19 10:13
1235038385.M765212P13483.tch-mailstore1,S=3927,W=4017:2,S

(root at tch-mailstore1:/mailstore/mail/domain.net/i/ian/mail/.postini/cur)
(2009-02-23 13:46:04)
# sieve-test -c ../../../sieve/default.sieve
1235038385.M765212P13483.tch-mailstore1\,S\=3927\,W\=4017\:2\,S
Fatal: Can't open mail stream as raw


Can anyone suggest what this error means?

Thanks,

Ian
