Hello, I'm a new Zimbra user. It's also the first time I setup a Linux server (Ubuntu Server 8.04)
My problem is we can't download messages using the POP3 protocl.
When we configure a POP3/SMTP client like Outlook Express or Windows Mail we receive the following error:
messaggio “ERR – Only valid after entering TLS mode”
This is a fresh install, the only things I did were:
- install and configure bind9
- close the relay as soon as Zimbra was up and running
- create the first user
The POP3 service is available since I can telnet in port 110 from the Internet
On the administration console the only reference to 'TLS' is under MTA, both under 'general settings' and 'Server'.
My Zimbra version is 6.04
Hoping to get your help, this installation means a lot to me (this is only a test for now but we want to dismiss our Exchange servers in a couple of months)
