Mail-crypt won't encrypt emails
Hi,
(Reposting as my previous post got zero replies.)
We're running Dovecot 2.2.36 and we need to set up the mail-crypt plugin to encrypt all incoming and outgoing emails. Outgoing emails seem to get encrypted fine but the incoming ones don't. We tried everything including this config:
mail_attribute_dict = file:%h/Maildir/dovecot-attributes mail_plugins = $mail_plugins mail_crypt
plugin {
mail_crypt_global_private_key = } also this one: plugin { mail_crypt_curve = prime256v1 mail_crypt_save_version = 2 } but to no avail. There are no visible errors, Dovecot restarts fine and
outgoing emails get encrypted. Any ideas? -- Kind Regards, Support Team

The plugin encrypts mail to be written encrypted at rest /on/ the server, and then decrypts the same mail when it is read /off/ the server. If it is working correctly mails sent will arrive at their destination readable. You need to go to the user directory where the mail is residing (example):
/mail/vhosts/XXXX/username/cur (wherever your user mail resides)
Choose any mail (example...
'1546546546546.Mdffgdfg535435.domain,S=4355435W=4r34534:3,S' ) will look
something like that (I have obfuscated the actual example but it will look
similar).
Now try and view it on the server using
postcat '1546546546546.Mdffgdfg535435.domain,S=4355435W=4r34534:3,S'
- If you get an error that looks something like:
*** ENVELOPE RECORDS '1546546546546.Mdffgdfg535435.domain,S=4355435W=4r34534:3,S' *** message_size: YPTED postcat: fatal: invalid size record: YPTED???
OR
- Alternatively you can try and > cat the message like a text file and at the start of the output you will see the string: CRYPTED
Then you will know the plugin is working.
If it shows the message in plaintext, the plugin is not active.
