Answer 1

simple mail transfer protocol- a protocol that enables you to send recieve emails. you need to be authenticated through this.

Answer 2

SMTP is the protocol used to send email.

To send a message to someone in a domain, you do not generally need to authenticate, you just connect to, say., smtp.example.com and say "mail to: [e-mail]" and it works.

But if you say "mail to: [e-mail]" it will say authentication required - otherwise you could send loads of spam through their server, which happened in the 1980's after spam was invented.



So if you work for example.com, and are on the road and want to send mail from your laptop, you must configure your email client (e.g. Thunderbird or Outlook) to use authentication in outgoing mail. Usually with StartTLS or SSL to protect your password. Consult your email provider about what settings to use as there are several possibilities, or just try them all until it works.

Answer 3

Any mail you want to send through a sensibly secured server MUST have a password given. Otherwise it would be possible for anyone to use your email account to send anything they wanted, all they would need to do was use your email address to send from. So whatever program you are using to send your emails and receive them will have outgoing server settings in the account configuration. This will require you to fill in your user name (often this is your email address) and then the password you set up when creating the account. In many cases there may be an option to tick a box for your server using the same outgoing as you used for incoming.

Answer 4

smtp sends email. An unprotected smtp server is what spammers pray to their gods for, so all smtp servers protect themselves, at least requiring a user name and password. Nearly all ISPs actually require you to be logging on to one of their points of presence with a valid user account before they'll let you near their smtp server.
