[rt-users] GnuPG problems with message decryption

[Martin Drasar]

Hello,

I have a question for anyone experienced with using gpg with gpg agent.

My situation is as follows:
- I have configured the RT and GPG according to this manual:
http://wiki.rediris.es/rtirwg/Public_GPGConfig
- The RT is able to verify signatures on incoming mail and is able to
sign mails
- It is however not able to decrypt incoming mails, which is strange
considering the signing and the decryption are practically identical
processes

I have this in the log:

This is happening with RT-4.0.5 as well as 3.8.7.

Any thoughts?

Thank you,
