Uebi to xmail problem from non tekkie, Can't send won't send....

I appreciate this question has already been raised, that is, that now Uebi has gone to xmail, I cannot send and get this message....
Could not send message to SMTP server. Check you have access to send messages via the server.
Server Responded: sender not yet given
Now, I have recently moved and the landlady doens't want net access in the flat so I have to use local net cafes for the forseeable future. As this concerns my business (I'm a Children's Entertainer) I need to resolve this asap, but the answers left to this message before had me baffled.

Any chance anyone could explain to me as though they were addressing a small child or dumb animal as I am not technically minded atall.

Many thanks for your help

So what is your question?

As far as I can see, this is not an XMail problem, but a Uebimiau problem/question. You may want to direct your question to the Uebimiau site.

I think you are confusing XMail Server with xmail.net. XMail Server is only a server platform for email systems. It does not have any client software built into it or directly associated with it. This includes webmail.

Have a look at http://www.xmail.net and see if that resolves your issues.

Hello,

I am using Xmail server and Telaen webmail which is based on uebimiau. What is there on xmail.net? is this a webmail? If yes then can i use it for my existing Xmail server webmail?

Thanks and regards,
Ajay Rathod.
