sendmail.mc could use a few more comments, and some organization to make it less
cryptic. Simply saying RTFM doesn't help when you are specifying something
undocumented (like specific parameters). Also, there are redundancies and
useless statments that should(?) be removed.
The last line of /etc/mail/sendmail.mc is
which is all fine and dandy, but isn't explained.
The "proper" way to add to the w class is with the more descriptive macro
dnl Mail sent to the loopback interface's FQDN should be delivered to this machine
Of course this is completely unnecessary since localhost.localdomain is ALSO
defined by default in /etc/mail/local-host-names. Pick one or the other. You
don't need both.
The there is
again, fine and dandy, but superfluous since they aren't defined by default
anyways. Perhaps what was meant is
dnl Remove the "dnl " at the beginning of the respective line if you need these
Though anyone setting up UUCP and BITNET relay (whoa, that brings back memories)
should be able to RTFM.
And since the #1 question asked is, "Why does my mail show up as comming from
email@example.com instead of firstname.lastname@example.org?"
dnl All mail from this host should appear to be sent from mydomain.com
Of course the Mozilla users won't have noticed this.
The first thing I always do is:
ln -s ../../usr/share/doc/sendmail/doc/ops/ops.ps .
ln -s ../../usr/share/doc/sendmail/doc/ops/ops.me .
Though how many people know how to read the *.me?
nroff -me ../../usr/share/doc/sendmail/doc/ops/ops.me op.man
Even stuffing the *.man in the docs directory whould be enough.
Well, you get the idea by now I hope. Something to consider for 9.0 :)
local-host-names does not contain "localhost.localdomain", but I have made
all other changes you have proposed above. I'll still have to think about
http://people.redhat.com/laroche/sendmail-8.12.6-3 contains the current rpm...
Hope to hear more feedback from you..., thanks a lot,

Thanks for the attention :)
My original note had a few errors, which you've found one. Specifically, you
are correct about local-host-names; I was thinking of the entries in the access
The manual is actually op.me not ops.me
And as long as you are listening, a pretty good spam fighter is:
dnl DNS based IP address blocking lists
Though Red Hat probably would want to comment (dnl) these out ... just like the
existing feature about allowing mail from unresolvable domains (eliminates at
least 50% of all spam).
I really wouldn't recommended putting those block lists in. And FYI, Spamcop bl
says it shouldn't be used in production and is experimental. Infact I wouldn't
recommend ANY of those blocklists.
I'll not add this list of spam filters, as they are changing
too fast. This should better be placed on www.sendmail.org or
similar sites, that can adapt to newer recommended sites faster.
