I have all my server settings set correctly according to Hughesnet but thunderbird tells me my login failed when I try to send any emails using my hughesnet smtp server. All my other accounts send okay using different smtp servers. I am frustrated that my main email account doesn't let me send emails. According to hughesnet my setings should be Outgoing server name: smtp.hughes.net Outgoing server port: 587 I have tried using SSL and that diddn;t help. I have tried different combinations of security settings that I could think of and none of them seem to help. I still get the login failed error message. I am at a loss as to the problem. Can anyone give me a hint as to what might be wrong with my settings?
