Hi, when after I compose email, when I click on send, now all of a sudden I get "failed to send" I have checked my email server, and it is up and running(hmailserver), and the other domains on my website(each domain has its own mail subdomain with roundcube in it)they can all send mail, it is just my rooksystems.no-ip.biz domain that can't for some reason. any ideas. thanks
