1. Security check
Open the confidential e-mail in the inbox of your PostMail e-mail account.
For security reasons pickup invitations for IncaMail messages are always provided with a signature which you should check together with the sender in each case.
Since PostMail does not display the signature, it is recommended to manually check the certificate in question. The file smime.p7s which is needed here can be found in the attachment in the message footer. Make sure the sender is email@example.com.
2. Opening the confidential message:
In the e-mail footer select the check box on the left next to the attachment secure-email.html. Then in the drop down list with the name “Choose action…” select the option “Download to hard drive”.
3. Confirming opening
Confirm any dialogue for opening the message attachment by clicking on “OK”.
