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
