O'Reilly's book on sendmail (Costales & Allman) is one of the best-written technical books in my collection. It's right around 1,000 pages, but don't let that intimidate you -- just read Part I (Tutorial) and you can use the remainder of the book as a comprehensive cross-reference. /var/log/mail may be useful. The main sendmail file is /etc/sendmail.conf. It's not too likely to mutate on its own, unless you've just upgraded or such. Does the mail get delivered when you (as root) run "sendmail -q" ? If so, sendmail isn't getting asked to send mail automatically. If you run: "sendmail -d0.4" you get a brief dump of some of the key internal settings. There are nearly 200 available debug settings for sendmail, and they are extensively cross-referenced and cleary described in chapter 37. You can watch sendmail process the mail in incredible detail with the right mix of debug opts. Eg., sendmail -q -d<opt1>,<opt2>,...<optn> Some useful debug option #s: 11.1 trace delivery 27.1 aliasing 31.2 header processing 35.9 internal macro def's 35.24 macro expansion 37.1 option setting 40.4 display file lines as they are read 99.100 prevent daemon from backgrounding Expect to see flames from people who don't like sendmail. It has an undeserved reputation for being hard to configure and full of security holes. Last time I looked, the vast majority of e-mail servers were running sendmail. This makes it a high-profile target for black-hats, and the sheer number of installations guarantees a steady flow of chatter regarding config issues. Don't be fooled! sendmail rocks! _______________________________________________ vox-tech mailing list [EMAIL PROTECTED] http://lists.lugod.org/mailman/listinfo/vox-tech
