Another option: prepend a message header in the SMTP server, and
log that message header in the SMTP client.
/etc/postfix/main.cf:
smtpd_client_restrictions =
check_client_access pcre:/etc/postfix/prepend_client
smtp_header_checks = pcre:/etc/postfix/smtp_header_checks
/etc/postfix/prepend_client:
/^([0-9.]+|[0-9a-f:]+)$/ prepend X-SMTP-Client-Addr: $1
/etc/postfix/smtp_header_checks:
/^X-SMTP-Client-Addr: (\S+)/ warn client address $1
Instead of X-SMTP-Client-Addr use something that is unlikely
to appear in other people's email.
This requires Postfix 2.5 or later.
