Disable outgoing mail

Hello,
Is it possible to disable outgoing mail for a user account? Just 1 account or just a mailbox in an account? If not disable, maybe just set to pending/for approval?
I want mailboxes for an account to be used for incoming mail only.

Hello,
Can someone assist in having KH block all outgoing mails for an account and allow only certain email addresses to send?

Hi Prune,
this interested me, so...
I don't think there is such facility in KeyHelp panel.
With a few minutes search I found the following, but have not tested, you could try this:
Open the Postfix config file:
/etc/postfix/main.cf
Insert the following code, just before the line "smtpd_client_restrictions"
(replace "user" with the username to block)
Code: Select all
authorized_submit_users = !user, static:all
source:
http://www.postfix.org/postconf.5.html
To block multiple users, I assume its like so:
Code: Select all
authorized_submit_users = !user, !user2, !user3, static:all
Save the file, then restart postfix.
Let us know how you go.
