In a corporate setting, we have our firewall pretty tight. We have port 25 outbound limited to just the Zimbra server static IP.
Zimbra Desktop doing Yahoomail works fine on incoming msgs, but not sending...
Do we need to allow outbound traffic on port 25 from machines that have ZDesktop running on Windows, and syncing Yahoo?
I have a user with 3 or 4 messages caught in ZD Outbox.
Firewall or nefarious captcha issue? (user noels57-at-yahoo.com)
firewall guy will not be happy
Would it work smoother if we used the Zimbra Web client? and not require port 25 from the workstatiion?
Thanks for help,
