Every time someone send me an email I get that message.
All keys are signed and trusted.
It's a problem with my key?
I get this in PGP log:
16:01:05 Email Info Processing message from <(null)> with subject: Problemas com o PGP
16:01:05 Email Info Decrypting AES256-encrypted message with key 'XX Xxxxxxx <xxxxxx@xxxxxx.com>' (0x2D8861B7:0xFC6BC2FF)
16:01:05 Email Info Verifying signature made by Zzzzzzz Zzzzzz <zzzzzz@zzzzzzzz.com> (0x2FA0C767) at 12:13:55 15/06/2016
16:01:05 Email Info Good Signature from Unmatched Key using SHA-2-256 hash algorithm
16:01:05 Email Info Address on signing key does not match sender, signature may not be valid
Why I have <(null)> instead of the email of the person that sent me that message?
There is several other account in the same server/domain and none have this problem.
Thank you.
