	postconf -e defer_transports=smtp; service postfix reload

- Unpause mail delivery:
	postconf -e defer_transports=; service postfix reload

- List messages in the mail queue:
	postqueue -p

- Informacio d'un missatge en cua:
	postcat -vq XXXXXXXXXX
	postcat -qe XXXXXXXXXX
	postcat -qh XXXXXXXXXX
		-> Message-ID: <...>

- Delete a message in the mail queue:
	postsuper -d "Queue ID from previous command"

Copiar TOTS els missatges a un mateix usuari
--------------------------------------------
- Add a user to the system so postfix can send BCC's of all emails to it
	adduser --system --home /var/archive/mail/ --no-create-home --disabled-password mailarchive

- Create the Mailbox layout for the mail archive:
	mkdir -p /var/archive/mail/tmp
	mkdir -p /var/archive/mail/cur
	mkdir -p /var/archive/mail/new
	chown -R nobody:nogroup /var/archive

- Configure Postfix to always send a copy of any emails sent to the mailarchive user:
	postconf -e always_bcc=mailarchive@localhost

- Configure the mail storage for the mailacrhive user so it uses the Mailbox format. This makes it easier to delete old emails:
	echo "mailarchive: /var/archive/mail/" >> /etc/aliases
	newaliases

- Restart postfix
	/etc/init.d/postfix restart

Copiar els missatges d'UN DOMINI
--------------------------------
/etc/postfix/main.cf
	sender_bcc_maps = regexp:/etc/postfix/domain_bcc
	recipient_bcc_maps = regexp:/etc/postfix/domain_bcc
