How to configure postfix to receive mails and keep them in queue but not sending them out

Question

How to configure postfix to only receive mails and put them into local queue but not actually forwarding mails so they keep inside /var/spool/postfix

Is there a reason you can't use a tool like MailHog or MailCatcher if you don't actually intend to send the emails? Such tools are explicitly designed to do what you want - catch all sent mail and display it. — Moshe Katz, Aug 17 '16 at 12:46
My goal was to just temp. forward mails — so like a postsuper -h ALL for future incoming mails — frlan, Aug 17 '16 at 13:01

Try adding the following:

/etc/postfix/main.cf:

smtpd_recipient_restrictions = 
...
check_recipient_access regexp:/etc/postfix/hold.regexp

/etc/postfix/hold.regexp:

/^/   HOLD

If you want to release all messages on hold, use postsuper:

postsuper -H ALL

I'm getting unused parameter for mtpd_recipient_restrictions and check_recipient_acces – frlan Aug 17 '16 at 10:53
"mtpd"? Did you make that typo in the comment or the config file? – I_GNU_it_all_along Aug 17 '16 at 10:55
Can you edit your post to include your main.cf file? – I_GNU_it_all_along Aug 17 '16 at 11:29

Is that to say that it's now working? :) – I_GNU_it_all_along Aug 17 '16 at 11:39
