Good Book for learning Sendmail

[MJT2k]

I am taking a class in college this semester on sendmail and my instrustor wants me to pick a book for the class. (This is a brand new course this semester). My instructor is thinking about using the "Sendmail" book from O' Reilly as a reference and he wants me to pick another book for the course. I have searched around the net for sendmail books but I can't really make up my mind.

Some books on Sendmail:

Sendmail, Second Ed. by O' Reilly & Associates.
Linux Sendmail Administration by Sybex (Craig Hunt Linux Library)
Linux: sendmail for Linux by Sams
Sendmail: Thoery and Pratice by Butterworth-Heinemann

What books do you recommend?

IMHO: O'Reilly is the way to go. Format and content are typically superior as a general textbook and reference to just about anything else on nearly any topic (best balance for the buck).

FWIW

Thanks Scott, but the way I understood my instructor is that he wants me to pick a second book for the class. I am not sure why.

What other book would you recommend?
