Hi, I would like to know is it possible and how to control user to send mail to the same domain/recipient in a specific period of time? E.g. user can only send 10 emails to xxxx@xxx.com within 1 min and if the number of mail exceed, the rest of the mails will be queued and send at a later time? Thanks a lot!

Regards,
Gary Lor

Curious, why restricting emails sent to same domain/recipient?

Coz some of our user's PC used to infected by virus and keep sending junk mail, we don't want to be blacklist by those domains especially those company which use Cisco mail appliance. Once you get listed, nothing you can do about it but wait till your reputation became normally again which usually takes a few days of time.

With SQL backends, you can partly do this with iRedAPD plugin 'amavisd_wblist', but it's a little complex to achieve this with SQL command line tool. With iRedAdmin-Pro, what you need to do is just putting the domains/addresses you don't want your users to reach.

Screenshot of iRedAdmin-Pro (in user profile page):

To disallow user to send email to external domain, just whitelist the same domain and block all (@.). But it doesn't support a time period.
