Would this also solve my (similar?) issue detailed here:

Cron Emails to External Email Address

Hello again all. I was wondering what would be the best way to enable Cron to send emails to external addresses. I want to forward yum-cron and backup messages to said external emails. I current have the SOGO package (bu not the mail server package) installed. Thanks!
