I am new to roundcube, previously I have only used Gmail, and I have never posted to a forum so please help me and point the way if this question already exists somewhere. I signed up for a freehostia account and roundcube was suggested along with it. I have made an email address and I can email to it but I cannot send any messages from it. I make an email and then I get a failed to send message once I try to send it. Did I need to download something or change something? Is there a specific way to enter mail addresses? Please advise.
