Chapter 1 - Electronic Mail on the Internet -> The Basic Internet Email System -> Sending Mail from
3rd list item in the ordered list after 1st paragraph

Typo for the acronym of Extended Simple Message Transfer Protocol (ESMTP). The list item currently reads "Sending the message to the user's chosen MTA via the Internet standard mail protocol, SMTP, or ESTMP" when it should be "Sending the message to the user's chosen MTA via the Internet standard mail protocol, SMTP, or ESMTP."

The caption for Figure 10-1 reads "POP usage for a dial-in bost" when it should read "POP usage for a dial-in host"

MIME is defined as "Multipart Internet Mail Extensions." Then it is

defined on page 39, paragraph three, as "multipurpose internet mail
extensions," saying "MIME is sometimes called 'multipart' or multimedia...
these names are incorrect."

The first sentence of the 2nd paragraph states: "The second (middle)

part can be built in one of three ways," but only two methods are listed.

The third sentences says: "the pid and the message count be be used"
The first "be" should be something like "may," "could," "should," etc.

The second sentence in the last paragraph on the page now reads:


"...but an ESMTP server will always have the string ESMTP in the
banner greeting."

I think this is incorrect. There is no specification that defines this as so.
Actually, some ESMTP server implementations do not include the word ESMTP.

The word "ESMTP" could be a hint. But clients should not assume that a server
supports SMTP only even if its greeting does not include "ESMTP".

1st paragraph

The MAIL and RCPT commands are described as taking the email address as an
argument surrounded by spaces. RFC 821 and the new RFC 2821 explicitly say
that the address is surrounded by angle brackets.

The examples on page 127 should be:

MAIL FROM:<byron@dogbone.net>

4th paragraph, last sentence

Last sentence reads:

"...the server has excepted the message...."

It should read:

"...the server has accepted the message...."

The link "ftp://ftp.funet.fi/pub/languages/perl/CPAN/MIRRORS" doesn't work. It
can be changed to "ftp://ftp.funet.fi/pub/languages/perl/CPAN/SITES."
