SignerCertSubject Parameter (Get-SMIMEPOP Cmdlet)
The subject of the recipient's public certificate used for signature verification.
Get-SMIMEPOP -SignerCertSubject string
During the signature verification phase of processing, the cmdlet will search the store specified in CertStore for a certificate that matches this parameter. If the store contains a match, it is used to verify the signature of the incoming message.
When this parameter is set, a search is performed in the current certificate store certificate with matching subject.
If an exact match is not found, the store is searched for subjects containing the value of the parameter.
When setting the parameter to a partial subject, CN= should be omitted. For example, the following code would find the certificate with subject CN=Test Certificate, OU=People, C=US
Example (Searching with partial subject)
If a match is not found, the parameter is set to an empty string, and no certificate is selected.
The special value "*" picks a random certificate in the certificate store.
