Hello!
I inform you that today I started testing of the S/MIME encryption and signature verification plugin for Roundcube. Encryption and signing, as I hope, will be implemented before the end of the year.
I need a wide variety of sample letters for testing. So I'll be very grateful if someone sends me a letter. My certificate for encryption is given below. The signed letter should contain the sender's certificate is attached.
If you are interested in my work, I'll be happy to answer questions.
Vladimir Gorpenko,
Moscow
