Following along with Dovecot upstream's description of how to integrate SpamAssassin and Dovecot for automatic training when moving messages in and out of a spam folder: https://wiki.dovecot.org/HowTo/AntispamWithSieve I created a sieve script that pipes messages to a shell script which, after determining the dbpath to use, tries to invoke /usr/bin/sa-learn. Which fails with an AVC when selinux is enforcing: Jul 31 19:05:24 mx.sfo2.do.logic.net audit[15931]: AVC avc: denied { getattr } for pid=15931 comm="sa-learn.sh" path="/usr/bin/sa-learn" dev="vda1" ino=7175 scontext=system_u:system_r:dovecot_t:s0 tcontext=system_u:object_r:spamc_exec_t:s0 tclass=file permissive=0 The problem is, sieve can execute bin_t scripts just fine (in fact, that's all it can run), but SpamAssassin is special in that it has it's own exec_t types. I'm not sure what the right fix here is (probably a one-off exception to the dovecot policy for spamc_exec_t? are there any other magic exec types that should be included as well?), or if there even should be a fix, but this seems like a reasonable enough use-case that I figured it was worth opening a ticket for.
This message is a reminder that Fedora 26 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '26'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 26 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
