Is there a good way on how to become a back-up server for someone. The way
listed in the postfix.org readme doesn't work:
put into main.cf
relay_domains = the.backed-up.domain.tld
relay_recipient_maps = hash:/ ..../postfix/relay_recipients
/....... /postfix/relay_recipients:
@the.backed-up.domain.tld x
