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 email@example.com by using RstrictPostfixReci .
some users can send email to this list :firstname.lastname@example.org,email@example.com
but I want to restrict sending mail to firstname.lastname@example.org too. some other users like email@example.com and firstname.lastname@example.org should send mail to email@example.com. 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?
