About using S/MIME digital-signature in web and mobile Zoho Mail.
Hello! I am using Zoho Mail from the mobile app-andorid and I can not send digitally signed emails as I do from the web using the S / MIME settings. (I not have problems with the digital sign trought the Zoho Mail web version) ¿Do I have to activate or install the pk12 certificate on my mobile? I use both the web version of the Zoho Mail and the mobile phone but one email is signed and the other is not, this makes the receiver suspicious of the issuer as I am advising clients and suppliers to avoid falsification verify the digital signature of my mail. Thank you FYI: "Protecting your emails just got easier with S/MIME and other new security updates" https://www.zoho.com/mail/blog/security-updates.html
