hello,

i have a problem with encrypting email that was send to an external user.

i have read the administrator and smime guide, and had no problem with the basic
setup.
i installed the  Djigzo VMware virtual appliance 1.2.3
at this time i had created a CA, an internal domain, an internal user and a
external user.
the encryption mode for this external user is set mandatory and on the Select
encryption certificates page the certificate is shown in green colour.
but when i send an email from the internal user to the external user i will get
these error massage in the MPA log:
