Hi, i have two questions about using "folder keys" for encryption:

1. If i use this method how can i decrypt files manually? You have to export the private key from mailbox attributes, see doveadm mailbox cryptokey export.

I noticed that this is probably bit too short answer, but for longer answer I'll write up information under

https://wiki.dovecot.org/Design/Dcrypt

soon.

2. If move a letter to another folder (or remove it), it will be unreadable. Log: imap(cloud): Error: read() failed: read(/home/cloud/Maildir/.Sent.test/cur/1485528498.M838579P2267....) failed: Decryption error: no private key available (uid=5, box=Sent.test, read reason=) imap(cloud): Info: Internal error occurred. Refer to server log for more information.

or: imap(cloud): Error: read() failed: read(/home/cloud/Maildir/.Trash/cur/1485528906.M150750P3081....) failed: Decryption error: no private key available

How fix it?

Thank you in advance. This seems to be a bug, and we are looking into it. Is the bug fixed in the new version (2.2.28)?

Unfortunately we are not able to provide a fix until 2.2.29, but it's scheduled for next month. I could provide you with a patch you can try if you want, once it's there.

Apologies for taking so long, we have now have a fix for this. Once it's been committed to master, are you by chance willing to try it out?

Hello Aki,

I actually faced the very same problem (testing 2.2.29.1 on a prestage server)/

I downloaded the new version of this file (only) and now things look definitively better:

Stage:

Debian Jessie, dovecot 2.2.29.1, keys in sql DB, client thunderbird

Process:

• receive a mail into inbox in crypted format

• read it ok

• create a new folder

• move the message in the newly created folder

• read it from thunderbird ok

When I have a bit more time, I will check if everything goes ok with sieve's "fileinto :create" :)

Cheers

Hello again Aki,

Just a simple confirmation: using sieve's "fileinto :create" seems to work properly also, using your temporary fix.

Cheers
