Error 10053 (SMTP 553)

[Paul Grinnell]

When attempting to send mail to my SMTP/IMAP4 server, Eudora 4.1.0.52
returns the following;

There has been an error transferring your mail. I said: DATA and then the
SMTP server (server name) said: 553 Authentication required from this
domain.

How can I configure Eudora to authenticate (send login and password) on
sends?

Any help is GREATLY appreciated ....... paul

You are *probably* connected to one ISP with your mail server or
return address configured to another, this is a common anti-spam
preventative by ISP's to keep unathorized users from using their
mail servers to distribute SPAM.

I see what you are saying, however, Netscape Mail works fine without modification
and Outlook 98 works with minor modification (an option to send your login ID and
password to the IMAP server on retrievals).

Any further thoughts?

thanks ..... paul

Try:
Add/Change the following line in your EUDORA.INI file under [Settings]

UsePOPSend=1

UsePOPSend - If UsePOPSend is on, Eudora will send mail using the POP3
extended command XTND XMIT. Since this is an optional command for POP3,
many POP3 servers do not support this command (Berkeley's popper, however,
does). There are pros and cons to using POP3 to send your mail. It
provides a level of security since it requires a username/password pair
to send mail messages, unlike SMTP. It is faster than SMTP, especially
when checking for new mail at the same time. It doesn't check for valid
recipients until the entire message is sent, and some implementations
(Berkeley's popper, for example) won't tell you which recipients are
invalid and will send the message to the valid recipients anyway.
