I'm running Dovecot 2.0.15 and Postfix 2.7.7 with postfix handing off to Dovecot's LDA. I am hosting multiple virtual domains with multiple users and everything is working. I would now like to create a permanent archive of all sent/received mail with each virtual user's mail saved to its own sent file and received file. This needs to be independent of the user's regular Maildir store since he can't delete or modify the permanent archive.

Any suggestions on how to best accomplish this either via postfix or dovecot?

Postfix has in main.cf

virtual_transport = dovecot

and in master.cf

dovecot unix - n n - - pipe flags=DRhu user=virtual:virtual argv=/usr/libexec/dovecot /dovecot-lda -d ${recipient} -f ${sender}

dovecot uses this:

[root@xxx andrew]# dovecot -n # 2.0.15: /etc/dovecot/dovecot.conf # OS: Linux 2.6.35.14-103.fc14.x86_64 x86_64 Fedora release 14 (Laughlin) ext4 auth_mechanisms = plain login cram-md5 disable_plaintext_auth = no mail_location = maildir:/home/vmail/%d/%n/Maildir mbox_write_locks = fcntl passdb { args = scheme=plain username_format=%u /etc/postfix/passwd driver = passwd-file } protocols = imap lmtp service auth { inet_listener { port = 12345 } unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0666 user = postfix } unix_listener auth-userdb { mode = 0666 } } ssl_cert = </etc/pki/tls/certs/xxx.com.crt ssl_key = </etc/pki/tls/private/xxx.com.key userdb { args = username_format=%u uid=5000 gid=5000 home=/home/vmail/%d/%n driver = static }

Thanks, Andrew
