by Marc 24 Sep '24

I am trying to modify the body of message with a global sieve script. It looks like that sieve-test does not generate this error, however I am not really able to verify the output. There does not seem to be an option to catch the output (new message) trace log 00000008: 3: finishing match with result: matched 00000029: 3: jump if result is false 00000029: 3: not jumping 0000002e: 5: filter action 0000002e: 5: execute program `sieve-command' 0000002e: 5: filter action: program indicated false result 0000005f: ## Finished executing script 'commands' require ["vnd.dovecot.execute","vnd.dovecot.filter","vnd.dovecot.debug"]; #if true if header :contains "Subject" "xxxx" { filter "sieve-command" ["-task","xxxx"]; } dovecot log (1166226): Terminated with non-zero exit code 2

bug dir copy group permissions?
by Marc 23 Sep '24

23 Sep '24

I am not sure if this page is correct, looks at least like this g+s not ok https://doc.dovecot.org/2.3/admin_manual/filesystem_permission/ work-around is to manually create dirs mdbox mdbox/storage mdbox/mailboxes. I would think this is a bug as files seem to be created correctly. group rights are not copied on directories, resulting in getfacl #effective:--- for the acl groups just testing with rm -R -f everything below usertest6 [@ shared]# ls -ln total 4 drwxr-xr-x 4 0 0 34 Sep 23 11:50 bak drwxrwx---+ 4 10001 10001 34 Sep 23 12:18 usertest drwxrwx---+ 3 10002 10002 19 Sep 23 11:51 usertest2 drwxrwx---+ 3 10006 10006 19 Sep 23 12:37 usertest6 -rw-r--r-- 1 0 0 121 Sep 23 11:46 README where are the group rights on mdbox?

Mail Backup from IMAP to POP3
by Reprobus 23 Sep '24

23 Sep '24

Hi, I'm in a situation whereas I need to backup my email from an IMAP server to a POP3 email client of my choosing. I'm hoping Dovecot can do such a task and is there a container to which I can run to set this up from ? My IMAP email server is maxed and I need to dump all the emails off the IMAP to POP3 as to clear it up. Thank You

shared mailbox not visible, acl_shared_dict stays empty
by Marc 22 Sep '24

22 Sep '24

I am creating the mailbox like this: doveadm -o mail_gid=testgroup2 mailbox create -u usertest shared/sharedtest1 I can set acl's (I think), at least the acl get produces the same. doveadm acl set -u usertest shared/sharedtest1 user=usertest6 lookup read write write-seen insert post doveadm acl get -u usertest shared/sharedtest1 However this file stays empty, I have read somewhere it should automatically be updated? acl_shared_dict = file:/tmp/shared-mailboxes.db How should I add entries manually there with: doveadm dict set file:/tmp/shared-mailboxes.db shared/sharedtest2 kempotest6 or with this syntax still???? https://www.dovecot.org/list/dovecot/2009-April/038922.html

public mailbox filesystem layout + permission best practice
by Marc 22 Sep '24

22 Sep '24

I have some issues testing public mailboxes with linux users and groups creating mailboxes for users for the first group is not really a problem: doveadm -o mail_gid=testgroup2 mailbox create -u usertest public/publictest1 doveadm -o mail_gid=testgroup2 mailbox create -u usertest6 public/publictest2 doveadm -o mail_gid=testgroup2 mailbox create -u usertest2 public/publictest3 If I remove usertest6 from testgroup2 roundcube instantly stops showing these mailboxes. However when I try to make a new public mailbox with a different group. I am getting errors. doveadm -o mail_gid=testgroup3 mailbox create -u usertest6 public/publictest4 missing +r perm: public/mdbox/storage/dovecot.map.index.log public/mdbox/storage/dovecot.map.index.log, we're not in group I have the impression I am doing something wrong here, maybe configure the namespace with different filesystem layout? I assume it is possible to work with multiple groups in one public namespace? public/ └── mdbox ├── dovecot.list.index.log ├── dovecot-uidvalidity ├── dovecot-uidvalidity.66f00cc7 ├── mailboxes │ ├── publictest1 │ │ └── dbox-Mails │ │ ├── dovecot.index.cache │ │ └── dovecot.index.log │ ├── publictest2 │ │ └── dbox-Mails │ │ ├── dovecot.index.cache │ │ └── dovecot.index.log │ ├── publictest3 │ │ └── dbox-Mails │ │ └── dovecot.index.log │ └── testthunderbird │ └── dbox-Mails │ ├── dovecot.index.cache │ └── dovecot.index.log └── storage └── dovecot.map.index.log namespace public { disabled = no type = public separator = / prefix = public/ location = mdbox:/home/popusers/public/mdbox list = yes subscriptions = no }

sieve combine or not to be combine ?
by Marc 21 Sep '24

21 Sep '24

I am cleaning a bit my sieve scripts and wondered if I should stick to this solution sieve_before = sieve_before2 = sieve_before3 = or just one sieve_before = and put all scripts in this one. What are the advantages / disadvantages of doing this?
