sieve setup. no svbin ?
by Voytek Eymont 09 Jun '19

since moving/upgrading system I've noticed I no longer get sieve script compiled, there is no dovecot.svbin created in /var/vmail/vmail1/sbt.net.au/voytek(a)tld.au/sieve what am I missing, how to check ? also, looking at sieve.log, I see a lot of May 31 06:32:50 lda(voytek(a)sbt.net.au)<1234><c4aVBfI98FzSBAAAyLbbsQ>: Error: sieve: Failed to initialize script execution: Invalid postmaster_address: invalid address `root' specified for the postmaster_address setting # grep root dovecot.conf postmaster_address = root what should I have ? # dovecot --version 2.3.6 (7eab80676)

macOS Notes.app IMAP Syncing Not Working
by Steven Smith 01 Jun '19

01 Jun '19

I’m requesting help getting macOS’s Notes.app to sync notes with a new dovecot IMAP server. Thanks to dovecot’s excellent online documentation and help from this list, I have a new perfectly functioning IMAP server. The issue is that macOS Note.app does not sync with this server. However, iOS Notes.app *does* sync and work well with this IMAP server, and the differences between macOS and iOS Notes apps are well known. (Thanks, Apple.) https://apple.stackexchange.com/questions/265579/notes-wont-sync-via-imap-i… <https://apple.stackexchange.com/questions/265579/notes-wont-sync-via-imap-i…> https://jpmens.net/2015/09/28/experiments-using-imap-for-notes/ <https://jpmens.net/2015/09/28/experiments-using-imap-for-notes/> … I am migrating from a working Server.app system in which Notes.app syncing does work across all devices, and therefore have a working dovecot configuration from Server.app, although it does not contain an explicit configuration for the “Notes” mailbox. I would greatly appreciate any help or pointers for these questions: Does anyone have a working template for dovecot that works with macOS Notes.app? I’ve posted doveconf -n of both the new server and the old Server.app server below. Would you all be able to provide advice on TO-DO’s and NOT-TO-DO’s for mailbox/name-space reconfiguration as I try to muck around with a nicely working, deployed IMAP server? I believe that the solution has something to do with name spaces and separators, and I’ve already changed the separator from the original ‘/’ to ‘.’ on the working server without success or obvious changes. All the mail boxes on the new IMAP server look like this, *without* a prefix ‘.’: > ls -1 /var/mail/tld.domain.mail/username/mdbox/mailboxes/ > Archive/ > Deleted Messages/ > Drafts/ > INBOX/ > Junk/ > Notes/ > Sent/ > Trash/ All the mailboxes on the working Server.app mailserver look like this, *with* a prefix ‘.’: > $ sudo ls -1 /Library/Server/Mail/Data/mail/users/username > .Archive > .Deleted

[mail-crypt-plugin] Private key location in Folder Key Mode
by emordin 01 Jun '19

01 Jun '19

Hi, So I am trying to locate the private key in dovecot-attributes but I can't seem to find it. I have went thru the strings in the file with the lib-dcrypt document as a guide but the private key doesn't seem to be in there. I'm guessing the private key is an internal attribute located here '/private/vendor/vendor.dovecot/pvt' , but according to the mail-attribute.h file that location is not accessible. Is this true? Or is there a way to see the private key? Thanks. Sent with [ProtonMail](https://protonmail.com) Secure Email.

> Can you try rm dovecot-attributes file? Okay it worked. I kinda did that by 'rm -rf' the entire /var/vmail/domain, and then I ran the following: doveadm -o plugin/mail_crypt_private_password=desired_password mailbox cryptokey generate -u user -UR And I got the check mark and the ID string of characters. I sent a new email to the server, and was able to open and read the email =) I got confused on the docs... So only if using unencrypted folder keys, could I open a CRYPTED email and read it right away. But if using encrypted folder keys, first I would have to set a password for the key before I could open the CRYPTED email ? I thought logging in to the mailbox would connect the password to the key automatically. Thanks again. Sent with [ProtonMail](https://protonmail.com) Secure Email.

So when I tried this way I got the following output: user'@'host:~$ doveadm -o plugin/mail_crypt_private_password=desired_password mailbox > cryptokey generate -u user -UR user'@'host:~$ And when I tried this way I got the following output: user'@'host:~$doveadm -o plugin/mail_crypt_private_password=desired_password mailbox cryptokey generate -u user -UR Folder Public ID user'@'host:~$ In both cases I sent a new email to the server, and I got errors stating the mailbox can't be opened Sent with [ProtonMail](https://protonmail.com) Secure Email.

So I believe I generated a key successfully with: 'doveadm mailbox cryptokey generate -u user -UR' because I got the output with the check mark and the Public ID string of characters. However I still can't read the CRYPTED emails when logging in with IMAP.. i'm still getting the following error in the mail log: Error: read() failed: read(/var/vmail/[domain . com/user/Maildir/cur/](http://domain.com/user/Maildir/cur/)<email_index>) failed: Private key not available: Cannot decrypt key ... : error:03070068:big num routines:BN_mpi2bn:encoding error I've tried to list the key with 'doveadm mailbox cryptokey list -u user' but I'm only getting the following output: Folder Active Public ID And I've tried to create a password with 'doveadm mailbox cryptokey password -u user -n Password1' and I'm getting the following output: result: dcrypt_key_load_private(...) failed: password missing Also my settings in conf.d: 10-mail.conf - mail_attribute_dict = file:%h/Maildir/dovecot-attributes mail_plugins = $mail_plugins mail_crypt plugins{ mail_crypt_curve = secp512r1 mail_crypt_save_version = 2 mail_crypt_require_encrypted_user_key = yes } 20-lmtp.conf - protocol lmtp{ mail_plugins = $mail_plugins sieve } And my settings in dovecot-sql.conf.ext: driver = mysql connect = host=127.0.0.1 dbname=mailserver user=mailuser password=1234 password_query = SELECT email as user,password, '%w' AS userdb_mail_crypt_private_password FROM virtual_users WHERE email='%u'; In the virtual_users table I have: id, domain_id, email, password Any ideas what the issue may be?

Please disregard the previous question. But I have another...
