Description Grosswiler Roger 2012-11-23 15:59:04 UTC

Comment 4 Grosswiler Roger 2012-12-01 21:38:53 UTC
Doesn't work for me, is for the sieve-files a special labelling necessary? 

Now i have it all on system_u:object_r:mail_home_rw_t:s0 which works fine with deliver, but audit. log tells me now to use system_u:system_r:dovecot_deliver_t:s0

Comment 5 Grosswiler Roger 2012-12-01 21:51:27 UTC
Sorry, retested again, as it was strange...

now it works, with the same labelling as above.

Will give positive Karma for this.
