hi. I'm running on Fedora 42 and want to hide the Deleted Messages folder (because I want to use Trash instead). unfortunately this fails: mailbox "Deleted Messages" { hidden = yes } which I understand depends on the "mailbox" plugin. however, when I look in /var/lib64/dovecot, I don't see any such plugin. I also cannot find in the repositories any RPM that provides it. I understand it may be baked into the core binary but if so, enabling it should work, and yet if I do enable it, I get the error below: Sep 11 10:06:01 mail dovecot[739762]: imap(ekkis): Error: Plugin 'mailbox' not found from directory /usr/lib64/dovecot I would also like to use the alias_for but that also fails. sigh. I'm also struggling to make Sieve work.

Sieve Scripts via SQL Dicts in Dovecot 2.4 not working?
by Niklas Meyer 11 Sep '25

11 Sep '25

Hello everyone, I am currently working on porting the Dovecot 2.4 configuration from the latest 2.3 version. During this process, I encountered issues with the Sieve filters, particularly those related to SQL dict mappings. The previous (2.3) configuration looked like this and worked: |map { pattern = priv/sieve/name/$script_nametable = sieve_before username_field = username value_field = idfields { script_name = $script_name} } map { pattern = priv/sieve/data/$idtable = sieve_before username_field = username value_field = script_data fields { id= $id} } | This resulted in the following SQL queries on the MySQL server: |2025-08-1511:01:29.237511SELECTid FROMsieve_after WHEREscript_name ='active'ANDusername ='frittenjonas(a)derlinkman.de'2025-08-1511:01:29.236416SELECTid FROMsieve_before WHEREscript_name ='active'ANDusername ='frittenjonas(a)derlinkman.de'| As you can see, there are SQL mappings for |sieve_before| and |sieve_after|, alongside a local file loaded prior to the SQL settings, as they are user-based. In Dovecot 2.3, everything worked and the scripts were executed. In 2.4, however, they no longer run. I adapted the configuration for dict SQL mapping for Sieve filters according to the documentation: |dict_mappriv/sieve/name/$script_name{ sql_table= sieve_before username_field = username value_field id { } # The script name field in the table to querykey_fieldscript_name { value= $script_name} } dict_map priv/sieve/data/$id{ sql_table= sieve_before username_field = username value_field script_data { } key_fieldid { value= $id} } | This also results in the dict proxy querying the database with the same pattern as before: |2025-08-1511:11:47.175184SELECTid FROMsieve_after WHEREscript_name ='active'ANDusername ='frittenjonas(a)derlinkman.de'2025-08-1511:11:47.172952SELECTid FROMsieve_before WHEREscript_name ='active'ANDusername ='frittenjonas(a)derlinkman.de'2025-08-1511:11:47.155786SELECTid FROMsieve_after WHEREscript_name ='active'ANDusername ='frittenjonas(a)derlinkman.de'2025-08-1511:11:47.136030SELECTid FROMsieve_before WHEREscript_name ='active'ANDusername ='frittenjonas(a)derlinkman.de'| However, unlike in 2.3, it now queries the DB twice.

Sample with spool file: .mbsyncrc, Isync, Information Lifecycle Management, dovecot, GMail, IMAP
by Philip Bondi 10 Sep '25

10 Sep '25

Hello to all: I wanted to offer my working .mbsyncrc to the community. I also have a spool file to share. In my opinion, 15 Gb on our Google accounts is no longer enough. Google Photos keeps prompting to enable backup. Most people are going to exceed this quota. In my opinion, this is manifestation of serious "platform decay". This is starting to affect all my immediate family members. In my opinion, one should have methodology to move GMail away of Google for Information Lifecycle Management. To achieve, I have setup Debian 12 virtual machine on QNAP running Dovecot. This setup is beyond the scope of this article. I setup Isync to sync gmail to my Debian 12 virtual machine. Then I wrote a script to move the gmail to local mbox. Isync will then purge the email from Gmail. https://www.snbforums.com/threads/sample-with-spool-file-mbsyncrc-isync-inf…

Hi, I'm having issues while installing Dovecot 2.4 on a Rocky Linux 8.10 server. This server was running Dovecot 2.3 but I wanted to upgrade it to 2.4.

Is it possible to use literal %2F inside a dovecot.http.client request url?
by hmmmz1000＠gmail.com 07 Sep '25

07 Sep '25

Hello, I'm using dovecot (2.3) lua with dovecot.http.client but I need the request url to have an url encoded slash (/) as %2F (or %2f) but if I enter for example https://test.com/%2F/test it looks like it changes it to a slash (https://test.com///test) in the http debug log (also the request fails as it's not %2F). I've also tried with %252F to encode the % but that doesn't change at all (keeps being %252F) & also tried with %%2F and \%2F but that gets the errors "Expecting hex digit after '%', but found '%'" for %%2F and "invalid escape sequence" for \%2F. Does anyone have an idea how to solve this or if it's even possible?

I have a dovecot system running in my kubernetes cluster that i use to gateway some emails to imap that are in turn used by systems that poll for email. No people are involved. Its been running for sometime on 2.3, i've now updated the base container to 2.4 and i have two problems, perhaps related, perhaps not. I'm assuming its related to my config changes for 2.4, but I'm kind of at my wits end.

The 2nd error, again, perhaps related, the user doing the poll for new email doesn't see it (despite I see the email delivered to the 'new' dir, it doesn't get picked up and moved to 'cur').

Below is my config file. In /home/support/Maildir i have the new, cur, tmp etc. There's no mention of 'INBOX', which i think my previous had (mail_location = maildir:/home/%u/Maildir:INBOX=/var/mail/%u/Maildir was previous) Any advice? I'm not sure where to go from here. dovecot_config_version = 2.4.1 dovecot_storage_version = 2.4.1 auth_mechanisms = plain login auth_allow_cleartext = yes #disable_plaintext_auth = no mail_privileged_group = mail #mail_location = maildir:/home/%u/Maildir:INBOX=/var/mail/%u/Maildir mail_driver = maildir mail_path = /var/mail/%{user | username}/Maildir mail_inbox_path = /var/mail/%{user | username}/Maildir userdb passwd { fields { home = /home/{%user | username} mail_driver = maildir mail_path = /var/mail/{%user | username}/Maildir mail_inbox_path = /var/mail/%{user | username}/Maildir } } passdb pam { service_name = dovecot } protocols = " imap" namespace inbox { inbox = yes mailbox Trash { auto = subscribe # autocreate and autosubscribe the Trash mailbox special_use = \Trash } mailbox Sent { auto = subscribe # autocreate and autosubscribe the Sent mailbox special_use = \Sent } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 } } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } ssl=yes ssl_server_cert_file = /run/ca/tls.crt ssl_server_key_file = /run/ca/tls.key log_path = /tmp/dc.log mail_debug = yes ssl_min_protocol = TLSv1.2 log_debug = category=email # verbose_ssl=yes #auth_verbose=yes #auth_debug=yes
