If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
A digital signature as defined in the PKI (public key infrastructure) model features non-repudiation whereby the signature identifies your identity and can only be sent by you. Do you want to secure your emails? If this is the case you'll need to request a personal email certificate from a CA like thawte or VeriSign which allows you to digitally sign and encrypt emails.
