although built-in bcc won't give envelope, there seems some tricky ways to do. for example: recipient_delimiter = + recipient_bcc_maps = pcre:/etc/postfix/bcc_map.cf and bcc_map.cf: /^(.*)@(.*)$/ archive+$1=$2@localhost then I can get the envelope for received mails. but I can not find the tricky way for sender_bcc_maps. if I need to write some script to handle this, any suggestion where to hook? thanks a lot for help!!
