SSMTP does not use /etc/aliases and does not resolve recipient address aliases; it sends to the specified address. For example, logwatch sends through sendmail by default logwatch.
Use mail to forward local recipients to external addresses: /etc/mail.rc
# Multiple addresses can be specified for one name
alias root [email protected]
alias root [email protected]
#
alias postmaster [email protected]
Verification:
