I want to send a payroll file to banks by secure e-mail. I don't have any background about secure e-mail, I searched in google and found many result, please can you offer me any advice?
more details :- Our major concern is the secutiry of the payroll file itself (attached by email), the email body can be plain. as for the client we need to find the proper command line client that can support our selected model of secure email.
and i don't care about the other side "bank" what it use ... because if the bank need any software installation or configuration i will go to bank and do it
