PGP Desktop: Several Signing Keys with one e-mail account?
I have different communication partners that do *not* accept the same key for signing. This is especially a problem with partners (companies) that require S/MIME with X.509 certificates (keys) authenticated by one, but not another Certification Authority. Thus, I have more than one X.509 certificate (key) for signing. And I need to send messages to recipient A signed with certificate 1, to recipient B signed with certificate 2 and so on.
But PGP Desktop seems only to accept one signing key (or certificate) per account, which cannot be modified in different "Policies" with respect to different recipients. I do not want to have to have different accounts for outgoing mail to different recipients (that would be too confusing).
(a) Is there any way to deal with this? A workaround?
(b) If not: This is a serious feature request.
