The solution is built into Postfix.
Give each message a BCC recipient, and route that recipient to
an archive file whose name is dated.
/etc/postfix/main.cf:
always_bcc = [EMAIL PROTECTED]
transport_maps = hash:/etc/postfix/transport
bcc_destination_concurrency_limit = 1
bcc_destination_recipient_limit = 1
/etc/postfix/transport:
[EMAIL PROTECTED] bcc:
/etc/postfix/master.cf:
bcc unix - n n - 1 pipe
flags=FR user=archive argv=/some/where/save_headers
/some/where/save_headers:
#!/bin/sh
outfile=`date +%Y%m%d`
(echo ""; echo ""; sed '/^$/q) >> /some/where/$outfile
Result is a file named after the date, with headers separated
by two empty lines.
