Just trying to confirm a few things.
We have a user who wants to use the sf.com zimlet and who also wants to be able to send email through the ZCS server from within Salesforce.
From our earlier notes on ZCS 4, we needed to:
zmprov modifyCOS salesforce \
+zimbraProxyAllowedDomains '*.salesforce.com' \
as well as add all thirty-odd of the 204.14.232.xxx and 204.14.234.xxx Salesforce.com server IP addresses to Trusted Networks.
Is that still the case in ZCS 5?
