Reconfiguring all clients is a huge workload.
So various senders are sending alerts mails with various from fields
these are all internal domains.
I use for this a generic map:
main.cf:
smtp_generic_maps = pcre:/usr/local/etc/postfix/generic
generic:
/^(.*)@([^@]+\.)?internal\.domain$/ $1@external.domain
This rewrites the domain part to match your external.domain
