Hello,
I'm in the process of moving our mail server from RHEL 6 to RHEL 9. We
will be moving to:
# dovecot --version
2.3.16 (7e2e900c1a)
My issue is that sieve does not appear to work on the new setup, where
it does work on the old one. I made a simple filter rule:
# cat /u/mail0test/.sieve/ingo.sieve
# Sieve Filter
# Generated by Ingo (http://www.horde.org/apps/ingo/) (06/28/2024,
11:14:52 PM)
require "fileinto";
# Test
if header :comparator "i;ascii-casemap" :contains "Subject" "filtertest" {
fileinto "Fun";
stop;
}
Upon sending an email to this test account, the following appears in
/var/log/maillog:
Jun 29 23:19:56 mail5 dovecot[3066980]:
lda(mail0test)<3066980><FA8fFtzOgGZkzC4AuM9lWg>: Warning: sieve: file

Yet:
# ll /u/mail0test/.dovecot.sieve
lrwxrwxrwx. 1 mail0test sysguest 17 Jun 28 23:26
/u/mail0test/.dovecot.sieve -> .sieve/ingo.sieve
# file /u/mail0test/.sieve/ingo.sieve
/u/mail0test/.sieve/ingo.sieve: ASCII text
That is the filter file I've pasted above.
I've set the following directives in /etc/dovecot/conf.d/90-sieve.conf
via puppet:
augeas {
"dovecot_sieve_settings":
context => "/files/etc/dovecot/conf.d/90-sieve.conf",
changes => [
"set plugin/sieve_dir ~/.sieve",
"set plugin/sieve_user_log ~/.sieve/log"
],
require => Package["dovecot"],
notify => Service["dovecot"];
}
The full configuration dump is attached.
/u in our environment is the path for user homedirs, which is an NFS
mount to a NetApp. The OS is Springdale Linux 9.2, a clone of RedHat
from before the IBM license change. It will soon be RHEL 9.4 as we have
obtained a license, but for all intents and purposes, Springdale 9.2 and
RHEL 9.2 should be considered bug-for-bug compatible. The arch is x86_64
with both machines mail5 and mail6 (replicated) having Intel(R) Xeon(R)
Gold 6244 CPU @ 3.60GHz and 768gb of memory. I have the same issue with
SELinux in both enforcing and permissive modes, so this is not a
permissions error due to SELinux.
Am I doing something wrong, or is this a bug? I've seen that there have
been some previous issues similar to this that ended up being bugs in
pigeonhole, so here I am.
Thanks,
Ben
