mutt and gnupg

[Thomas Göbel-2]

Hi listmates,

i have a problem with mutt and gnupg. I have set the gpg-options
described here: http://WIKI.mutt.org/?MuttGuide/UseGPG

I use mutt with getmail/procmail and msmtp to receive/send mail. I have
two mail-accounts (gmx.de and my university account).

If i send me a signed mail from GMX to GMX mutt tells me "Good
signature" and the status line tells "signature successfully verified".
Sending mail from university-account to university-account everything
works fine, too.

The problem exists if i send from GMX to university. Now mutt tells me
"BAD signature from" and "PGP signature could not be verified". Sending
mail from university to GMX and mutt and gpg work well.

The key is always the same and the key is made for both e-mail adresses.
If i open both mails in the sent folder mutt tells me for both mails that
the signature is successfully verified.

Thanks,
Tom

Is there any chance that the mail has been modified by the mail server on one
of the routes?

Personally I've had problems with the combination GnuPG and MS Exchange in the
past.
