We use delivery restrictions in our Exchange 2003 environment to limit the ability to send external e-mail to members of a Security group. I just wanted to verify if leveraging transport rules in Exchange 2010 is the preferred method going forward. There doesn't appear to be another method in 2010 for setting delivery restrictions on the connector. - Sean --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com<mailto:listmana...@lyris.sunbeltsoftware.com> with the body: unsubscribe exchangelist --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe exchangelist
