UNCONFIRMED errors and comments from readers: {502} Final paragraph; In "Talking to the MTA" you're giving an example of an SMTP transaction. But the format you're using for the "mail from" and "rcpt to" addresses are not correct as they're missing the brackets around the address. Here's an example of how it works/fails: eivind@vimes:~ > telnet vimes.eivind 25 Trying 192.168.0.1... Connected to vimes.eivind. Escape character is '^]'. 220 vimes.aminor.no ESMTP Postfix (2.0.16) ehlo aminor.no 250-vimes.aminor.no 250-PIPELINING 250-SIZE 40960000 250-VRFY 250-ETRN 250-AUTH LOGIN PLAIN DIGEST-MD5 CRAM-MD5 250-XVERP 250 8BITMIME mail from: eivind@aminor.no 501 Bad address syntax mail from: 250 Ok quit 221 Bye Connection closed by foreign host. eivind@vimes:~ > Note: This is with "strict_rfc821_envelopes = yes" in main.cf, so your example will _work_ with a default Postfix installation. {571} Complete page; The default entry from /etc/login.conf is shown and then it's described that certain limits are imposed ("The user may have up to 64 processes." for example) but the entry from login.conf shows all values as "unlimited". (577) Last paragraph; The book says that /etc/services lists the IP services the system supports. That sounds a bit incorrect to me. My native language is not English so I may misinterpret things, but that text could lead me to believe that FreeBSD supports the services in /etc/services such as 534 tcp/udp (MegaMedia Admin) etc. (584) 1st paragraph; The text gives an example from "cvs log Makefile" (on page 583), and on the top of page 584 it says "That's the purpose of the line head:," but the example on page 583 doesn't contain that text.
