[hostile123]

Hi, installed fresh 1.2.0, then enabled enigma in config,

same issue here clean RC 1.2.0 install => Plugin activated Option settings ok but if you click on key management I get the follwing error

Application Error (600): Enigma plugin: GPG binary not found. If you are sure the GPG binary is installed, please specify the location of the GPG binary using the 'binary' driver option.

Have you installed pear Crypt_GPG?

Looks like you have open_basedir restriction enabled in PHP config. Errors here are clear.

Are they using Plesk or something? Then they should read this article: http://kb.plesk.com/en/432

[wikrie]

Yes that's it I will also add a comment on the issue!

that was too easy I simply add the /usr/bin/ for the subdomain of mail system and then it works. And yes it seams to be an issue in combination of Plesk, I use Pleask 12.5 and there you can add the open_base_dir directly. Many thanks now I can encrypt my Mails. Only the key import is not working as I expect but I think it is a question of the file, I think I saved it in a wrong way. Will check this as next.

I also prefere to add /usr/local/bin/ instead of /usr/bin/ so that not all binary's are executable fro the PHP. So I have a better controle of the binarys ...

many thanks WiKrIe

I would say issue can be closed, the owner still not answer in anyway and I can say it works.

Not Roundcube issue.

Please help me. Thanks in advanced.

You need to have gnupg installed. Either compile it, or install it from a package. On CentOS for example, it's easy: yum install gnupg
