Sure. with iRedMail-0.9.2 and iRedAdmin-Pro-LDAP-2.3.1, it's a little harder to manage this per-user white/blacklisted recipients, but it's much improved in upcoming iRedMail + iRedAdmin-Pro release. screenshot attached for your reference.

It's done in iRedAPD plugin `amavisd_wblist` (note: this plugin is improved in upcoming iRedAPD-1.7.0 to support white/blacklisting recipients), and iRedAdmin-Pro manages the data. (of course you can manage data with SQL command line tools.)

Currently, you have to enable iRedAPD plugin 'ldap_recipient_restrictions', but it's removed in upcoming iRedAPD release. So you need to remove this plugin in /opt/iredapd/settings.py when upgrading to new iRedAPD release, and re-configure this white/blacklist stuff (with new iRedAdmin-Pro).

Here's the summary:

*) Enable plugins 'ldap_recipient_restrictions' in /opt/iredapd/settings.py.
*) Manage user's LDIF data with phpLDAPadmin or `ldapvi`, or other LDAP management tools.

Let's take your user 'user@domain.com' for example, this user is allowed to send email to 'gmail.com' and 'hotmail.com', but not other domains.

*) Add ldap attribute/value `mailWhitelistRecipient=@gmail.com` (without quotes) for your user 'user@domain.com'.
*) Add ldap attribute/value `mailWhitelistRecipient=@hotmail.com` for your user 'user@domain.com'.
*) Add ldap attribute/value `mailBlacklistRecipient=@.` for your user 'user@domain.com'.

That's it. Please test it and check iRedAPD log file /var/log/iredapd.log.

I'm afraid that it doesn't support per-domain white/blacklist. That's why we removed this plugin in upcoming iRedAPD release.

BTW, iRedAPD + iRedAdmin-Pro supports global, per-domain and per-user white/blacklists.

right.

correct.

New releases of iRedMail + iRedAdmin-Pro are scheduled to be released in November, after OpenBSD 5.8 release and new Ubuntu releases (hopefully).

It's not recommended to try the latest iRedAdmin-Pro development edition right now, because several components are not stable yet. If you're interested in giving it a try, i summary the steps below, hope it helps you make the decision.

*) Upgrade iRedMail to the upcoming iRedMail-0.9.3 by following this (DRAFT) upgrade tutorial:
http://www.iredmail.org/docs/upgrade.ir … 0.9.3.html

if you're not running iRedMail-0.9.2, please upgrade your iRedMail first. All upgrade tutorials are available here:
http://www.iredmail.org/docs/iredmail.releases.html

*) During upgrading iRedMail, you need to upgrade iRedAPD to the latest iRedAPD-1.7.0. it hasn't been released yet, but you can check out the latest development edition.

Important things are:

1) iRedAPD requires a new SQL database `iredapd`, used to store throtte settings (and throttle tracking info).
2) iRedAPD requires a new SQL table `amavisd.outbound_wblist`, used to store white/blacklists for outbound emails.

Once you have iRedMail-0.9.3 and iRedAPD-1.7.0 running, it's ok to upgrade iRedAdmin-Pro as usual (run 'tools/upgrade_iredadmin.sh').

WARNING: as mentioned above, both iRedMail + iRedAPD + iRedAdmin-Pro are still under development, something may be changed in final release, the changes between current development phase and final release will not be covered in iRedMail upgrade tutorials.
