Re[2]: sendmail problem

[Victor Wolski <victor evilgeeks com>]

Hi Pete, I think what Yee was talking about was SMTP and not POP3.
Yes when downloading email to a client from a POP3 connection, a
username and password is required to get that users email. But for
SMTP, sending of mail, no username and password is required. Sendmail
just makes sure that the person (host) sending the mail is a valid
relayer. But if Sendmail does not validate the host then an "No
relaying aloud" error pops up on the mail client. One way I have seen
this handled is to allow everyone on the internet to relay through a
email server but authentication is enabled. So loging in is required
for pop3 and SMTP. But I've never seen anywhere in Sendmail to enable
SMTP authentication. Maybe someone could enlighten us.

PR> Yee,

PR>         I'm not sure exactly what you are trying to do here. As far as setting up a POP3 server, authentication is part of the process. If you telnet to your mail server (ie. telnet localhost
PR> 110) you will come to the server (as will any email program) and be required to login. Thus, sending user username (enter) pass password (enter) and then typing list will give you a list of
PR> messages. retr 1 will give you the contents of the first message and so on. The only thing I can think of is that you are thinking of the client saving the password on their mail program like in
PR> Outlook Express. If this is the case then I would suggest unchecking save password (note: this makes for cranky users).
