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? Also am I suppose to add the 'userdb_mail_crypt_private_password' into the table and put the virtual users email login password in there? Or is it suppose to be a temporary query? Thanks.

Please disregard the previous question. But I have another... I have set up Folder Key encryption, and have sent an email to my mail server which is CRYPTED, however when I try to login to read the email I'm getting a 'Private key not available: Cannot decrypt <...>: error:03070068:bignum routines:BN_mpi2bn:encoding error'. I've tried to list the user key and generate a new keypair two different ways and have gotten the following output: doveadm mailbox cryptokey list -U user output: Folder Active Public ID doveadm mailbox cryptokey generate -u user -U output: Folder Public ID doveadm mailbox cryptokey generate -u user -Uf output: Panic: file doveadm-mail.c: line 405 (doveadm_mail_next_user): assertion failed: (ctx->exit_code !=0) Error: Raw backtrace: ............. Aborted Any advice? Sent with [ProtonMail](https://protonmail.com) Secure Email.

SIGABRT on fetching mail

However, I'd not attach such a file to a post to the mailing list, so where can I put that? Send it directly to You? Kind regards Peter PS: I'm using Arch Linux - probably the hint above could be added to https://www.dovecot.org/bugreport-mail as a hint for other Arch users, as it's much easier than using gdb for those not using it?

In Folder key plugin operation mode, using the following password query: password_query = SELECT \ email as user, password, \ '%w' AS userdb_mail_crypt_private_password \ FROM virtual_users WHERE email='%u'; Say I have two 'email' users...will each 'email' have a 'userdb_mail_crypt_private_password' field with a plaintext password (%w) in it? And is the 'userdb_mail_crypt_private_password' used automatically to decrypt the user private key which is stored in 'mail_attribute_dict' ?

Hello, I've got a Dovecot 2.3.x setup. Currently it's running Maildir storage. I'd like to convert that to Dbox specifically Sdbox safely. I'm also looking to at the same time or shortly thereafter encrypt the email storage with mail_crypt. Any help appreciated. Thanks. Dave.

Hi People, I'm use dovecot in my mailbox system, until last month i used the dovecot version 2.0 and now i use version 2.2, version 2.2 works well for me, but i have one small problem, in sieve. In version 2.0 i had rules in sieve similiar to rule bellow: if allof (true){ keep; fileinto "INBOX"; redirect "xxxxxx"xxxxxx.com.br"; stop; } In the new version 2.2 this rules above, i have one problem duplicate messages in account from my clients, in paste INBOX, therefore, i changed rule to bellow ( with remove fileinto inbox) if allof (true){ keep; redirect "xxxxxx"xxxxxx.com.br"; stop; } Dovecot really changed your behavor, i did right to fix this ? Thanks a Lot, Marcelo
