if !/backup.*@/ /^([^+_]*).*@(.*)/ backup+${1}.${2}@domain.tld endif I currently have the above in recipient_bbc
/etc/postfix/main.cf: recipient_bcc_maps = pcre:$config_directory/recipient_bcc.pcre And this works perfectly and stores a copy of all email (sent and received) in a backup account that is set to delete messages after 7 days. This allows me to recover messages which people have deleted or accidentally marked as spam. However, I would like to exclude a specific domain from this backup including all mail TO and FROM the domain. -- Apple broke AppleScripting signatures in Mail.app, so no random signatures.
