Hello, I noticed that since a recent update my sieve filter is not working anymore. I tried to debug it with mail_debug = yes in /etc/dovecot/conf.d/10-logging.conf but I can’t seem to get to the root of the problem. Thanks in advance!
Hello @chris
your filter connect to Roundcube ? same issue happened with 1.6.2 solved by review basic setup of the filter and found port blocked by csf so unblocked it
I don’t know the reason but solved
note : after update to 1.6.5 issue didn’t appear
I wish this help you
Thanks a lot for your help @nada. I’m fairly new to this setup: you’re talking about port 4190, am I correct? Where / how exactly did you unblock it? (If I allow that port in the Firewall gui for the servers ip nothing changes.) These are my (untouched) dovecot config files:

Roundcube should work fine without opening ports.
What is the exact error?
Thanks @eris, I’m trying to find out what the cause of the issue is. I added mail_debug=yes to root@host:/etc/dovecot/sieve# nano 20-managesieve.conf within the protocol sieve { } block.
Are the logs being written to /var/log/syslog by default?
I think /var/log/dovecot?
I thought so too: so I checked again /var/log/dovecot.log but nothing other than login/logout logs:
Jul 30 10:11:12 imap-login: Info: Login: user=<[email protected]>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=7271, TLS, session=<rOtRTwHlUrt/AAAB>

Unfortunately I can’t seem to activate the logging / debug sieve. I checked if managesieve-login and dovecot-managesieved are installed and checked these config files with the original installation files:
20-managesieve.conf
90-sieve-extprograms.conf
90-sieve.conf
Could you suggest me where else to look, or do I need to check the status of certain services?
I’m on HestiaCP 1.6.5 with Ubuntu 22.04 (upgraded from 20.04).
P.s. during the last upgrade these services were restarted by default:
Restart should not affect them…
Exactly, I thought so too… Sieve also seems connected:
root@host:~# telnet host.myhestiacp.com 4190
Trying 127.0.0.1...

If I enable mail_debug = yes in /etc/dovecot/dovecot.conf I get this as, hopefully helpful, log output:

What is exactly not working?
Doesn’t it filter or doesn’t it send any forwarders / auto reply?
It doesn’t want to filter or send any forwarders and replies when I configure them from Roundcube sieve. (Forwarders and replies do work if I set them up within HestiaCP GUI).
So neither the default x-spam-flag spam filter or any custom filters work. F.e. if I try to filter e-mails with subjet ‘singer’ into the folder ‘Singing’.
require ["fileinto"];
# rule:[SPAM]
if header :contains "x-spam-flag" "YES"
{
fileinto "INBOX.Spam";
}
# rule:[Singing]
if allof (header :contains "subject" "singer")
{
fileinto "Singing";
}
PS. Can it be a problem of incorrect file permissions / ownship?

Should be fine
Thank you @eris. Do you have any other thoughts on this issue? I’m slowly pulling my hair at this point…

Ok… I found the solution by editing: /etc/exim4/exim4.conf.template
-
Within the ‘Routers Configuration’ I changed the
localuser:
Old value:transport = local_delivery
New value:transport = dovecot_virtual_delivery -
Within the ‘Transports Configuration’ I added the following block right between the
local_spam_deliveryand theaddress_pipe:
dovecot_virtual_delivery:
driver = pipe
command = /usr/lib/dovecot/dovecot-lda -e -d $local_part@$domain -f $sender_address -a $original_local_part@$original_domain
delivery_date_add
envelope_to_add
return_path_add
log_output = true
log_defer_output = true
user = ${extract{2}{:}{${lookup{$local_part}lsearch{/etc/exim4/domains/${lookup{$domain}dsearch{/etc/exim4/domains/}}/passwd}}}}
group = mail
return_output

You did upgrade from 20.04 to 22.04?
That might the issue
Yes, I did. But I did follow the documentation with these commands, so I never thought it could be an exim4 related issue:
rm -f /etc/exim4/exim4.conf.template
cp -f /usr/local/hestia/install/deb/exim/exim4.conf.4.94.template /etc/exim4/exim4.conf.template
Anyway, I’m glad it’s working again since it’s a vital function in my setup/ for my clients.
