When using the S/MIME Integration, it would be useful if sender certificates would be automatically imported to the certificate store as it is done in e.g. Thunderbird. This would greatly ease replying to encrypted mail for every user of the S/MIME Integration that is regularly sending encrypted mails.
The certificate for this can be extracted from every signed mail.
There is no button visible, as it says in the FAQ.
I have already imported the certificate. Decryption now also works for new emails, but the old ticket is still not visible.
