Setting up Zimbra for company's mail server. Help!

[chris-chris]

Hi there, I've been assigned the job to install Zimbra for my company. We currently have our emails hosted with exchange but want to move away from it. We have a total of 13 mailboxes that we need hosted with zimbra.

I've been trying for the past 3 days to set up Zimbra and have it work fully with ThunderBird v3.1.10. I've managed to get everything set up aside from being able to send message via thunderbird. I get the following message when trying to send.

"Sending of message failed
The message could not be sent because the connection to SMTP server mail.mydomain.co.uk timed out. Try again or contact your network administrator"

Please note, I am able to receive with thunderbird, just not send. Can anyone shed some light on this? Thanks
-Chris

Do you have a firewall in front of Zimbra?

What port did you set Thunderbird to use when connecting to the SMTP server?

Did you set up authentication/SSL for your SMTP settings?

I might also suggest checking out Zimbra Desktop for the clients, so that you can have similar features to what Outlook gave you with Exchange.

There is no firewall in front of zimbra.

I set the port in Thunderbird to 25

I tried setting SSL in thunderbird for SMTP settings. Do you mean SSL settings in Zimbra? Then I don't know... How do I check?

Zimbra Desktop doesn't allow drag+drop of emails to a folder on disk. This is essential for workflow, with thunderbird this is possible with a addin. That is why I'm not considering Zimbra Desktop for a mail client
