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' 1. 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 2. 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. -- Sent from: http://dovecot.2317879.n4.nabble.com/
