Can someone advise please eM Client fro MacOS support S\Mime certificates? It allows to import certificate but unfortunately I can’t send an encrypted by these certificates email and I got a message that my S\MIME certificates are not valid.
I’m ready to buy Pro version of eM Client because I’m found it very suitable for my tasks but I need to be sure that I can work with emails encrypted by S\MIME certificates.
Thank You in advance
