I'm using zcs-6.0.8_GA_2661.RHEL5.20100820051652 on Centos 5.5 with 5 domains
I have three different Distribution list
I restricted sending to firstname.lastname@example.org by using RstrictPostfixReci .
some users can send email to this list :email@example.com,firstname.lastname@example.org
but I want to restrict sending mail to email@example.com too. some other users like firstname.lastname@example.org and email@example.com should send mail to firstname.lastname@example.org. But I don't know how can I configure to restrict others to send mail to this list. Can Zimbra assign different permitted senders to different distribution list?
