sendmail, 2nd Edition
by Bryan Costales with Eric Allman

Here are the changes that were made in the 4/00 reprint:

Here's a key to the markup:

        [page-number]: serious technical mistake
        {page-number}: minor technical mistake
        <page-number>: important language/formatting problem
        (page-number): language change or minor formatting problem
	?page-number?: reader question or request for clarification


<xxiv> The following text was added to the preface:

{86} The text used to read:

	"gw" "@" "wash" "." "dc" "gov"

The line now has a "." between "dc" and "gov" to read:

	"gw" "@" "wash" "." "dc" "." "gov"


{378}  The first line of the page used to state:

	"The '-oTimeout.queuereturn=99d' causes . . . "

It now reads:

	-OTimeout.queuereturn=99d


(494) This sentence, which was present in the sgml files but not in the text
was added to the text:

	" Finally, the recipient address also needs to be rewritten 
	for inclusion in the header and envelope of mail messages 
	(See Figure 29-3)."
	

(495)  The first paragraph used to read:

	"once to select the delivery agent. It is used as input to 
	rule set 3, as are all addresses. It then flows through rule 
	set 2, then through the R= rule set selected by the delivery
	agent, and finally through rule set 4."

It now reads:

	"Recall that the recipient address was already used once to 
	select the delivery agent. The recipient address is used as 
	input to rule set 3, as are all addresses. The recipient address
	then flows through rule set 2, then the R= rule set selected by 
	the delivery agent, and finally through rule set 4.


<1024> The following sentence was removed from the colophon:

	"Whenever possible, our books use RepKover, a durable and
	flexible lay-flat binding. If the page count exceeds RepKover's
	limit, perfect binding is used."
