The server response was: 503 This mail server requires authentication when attempting to send to a non-local e-mail address

My ISP requires a configuration that I can't find in Mozilla.
(I can recieve mail just fine from multiple POP accounts. I can't send,
though. Other settings seem to be fine: server, port, username, password.)
In Outlook, there's a checkbox to specify "server requires authentication"
prior to sending mail.
Is there an equivalent setting/feature in Mozilla?

...Mail sending through a mail server or ASP.NET mail component??
I'm building a webmail UI and theres one thing I would like to know:
What would be the feature or performance differences if I send my mails through my mail server COM API (hMailServer 4.3) or through ASP.NET mail component?
Performance likley negliable differences, even if sending 100 000 emails, the real time will be the sending of the email. If the API offers smarter batching of e-mails then it might make a difference. The advantages of using the .NET SmtpClient (which I assume is what you're referring) are that you're really not dependent on ...Sending Mail with FUNCKY to a recipient on a different mail server ERROR -14

I get this error when sending to a recipient on a different server:

Now question is: HO...Send Mail from my Mail Server
Hi, I tested the sample code which is used to send mail from asp.net page like SmtpMail.Send(....). Actually it works well. But here the mail was not stored in the send items of my email ID (From ID) when i sent a mail. I think you got my question. My question is every time i send a mail the mail will also be stored in the sent items. And also I want to send mails from my Mail Server. Please send your suggestions or links.Thanx,M. GANESAN
