[dovecot] spam mailbox is not created

[pedro-nonfree]

Fresh new install (3.6.4.6), executed the install.yunohost.org , the postinstall, configured the DNS in provider as expected, letsencrypt, etc. - I did not touch anything manually.

Everything is fine, but when I configure an email account in thunderbird spam mailbox is not created (which is essential to train spam).

Compared to another handmade email instance, yunohost instance is ignoring the content of /etc/doveconf/conf.d/15-mailboxes.conf, check doveconf command in handmade instance [1] and yunohost instance [2]

[1] handmade instance

# doveconf | grep -i mailbox
lda_mailbox_autocreate = no
lda_mailbox_autosubscribe = no
lmtp_save_to_detail_mailbox = no
mailbox_idle_check_interval = 30 secs
mailbox_list_index = no
managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave
  mailbox Borradores {
  mailbox "Correo no deseado" {
  mailbox Drafts {
  mailbox "Elementos eliminados" {
  mailbox "Elementos enviados" {
  mailbox Junk {
  mailbox Sent {
  mailbox "Sent Messages" {
  mailbox Trash {

[2] yunohost instance

# doveconf | grep -i mailbox
lda_mailbox_autocreate = no
lda_mailbox_autosubscribe = no
lmtp_save_to_detail_mailbox = no

This could be easily solved with a sieve rule. This rule would be part of rspamd integration with postfix and dovecot. I'm working on it.

I recently have had to use doveadm mailbox create -u USER Junk to do the trick for all users…

for user in $(yunohost user list | grep username | sed "s/    username: //"); do doveadm mailbox create -u $user Junk; done

Did you already put work into this, @zeroheure ?

[zeroheure]

No, not yet. Lack of Time, sorry.

I'd propose the following:

remove rules from /etc/dovecot/global_script/

Probably a different issue, but if a folder named junk does not exist (used by global rules), the execution of the rest of the users rules seems not to work.

This isn't what the user would expect and couldn't debug.

hook for new users

create a folder for junk

What this issue is about....

create message in folder for junk

Create a message in that folder warning the user not to delete the folder without changing the preconfigured rule.

create a rule in the users rule set

Move messages with X-Spam: Yes to that folder.

User then do see the rule and the dependency on the folder for spam in their interface. They can change the folder and the rule to their likings.

Some notes for ongoing work:

• /usr/share/yunohost/conf/dovecot contains the default configuration file.
• it offers via pre-ext.conf and post-ext.conf the option to include some more configuration
• all the files in /etc/dovecot/conf.d/ are ignored including 10-mail.conf and 15-mailboxes.conf to create automatically folders and tell dovecot of there special usage**?!**

If the above is correct I'd propose that we let dovecot generate the folders on first login by following the examples from conf.d .

Missing parts:

• adjust antispam_spam & antispam_trash for rspamd integration
  done: YunoHost/yunohost@e6e58ec

• change global sieve script into a user sieve script that is copied on user creation (hook)
