Hey guys,

I'm having a bit of trouble sending mail using thunderbird.

It's all setup, receives email but when I go to send it comes up with an error "Sending of the message failed. The message could not be sent because the connection to the Outgoing server (SMTP) mail.mobilemonster.com.au was lost in the middle of the transaction. Try again."

I am certain it's an issue with the Port, Connection security, Authentication method.

I have it currently set to:

Port: 587

Connection Security: SSL/TLS

Authentication method: Normal Password

It works fine when I use these settings in Outlook with my PC, but for MAC it just doesn't work!!

Any ideas?
