Redirecting mails
As explained in man aliases(5), you can redirect mails to various destination.
As example, you host jdoe@athome.tld and want to redirect every mails received by jdoe to batman@wayne.com.
Edit /etc/mail/virtuals and add :
jdoe.athome.tld: batman@wayne.com
You can set redirections in /etc/mail/aliases too. For system users, you can use their login only :
root: jdoe hostmaster: root postmaster: root webmaster: bruce jdoe: jdoe@domain.tld
Remember to restart smtpd so changes are considered :
# rcctl restart smtpd
Easy. 😎
