A little Sunday afternoon tweaking has me wondering. I've got these
two routers at the end of the routers section:
procmail:
debug_print = "R: procmail for $local_part@$domain"
driver = accept
check_local_user
transport = procmail_pipe
require_files = ${local_part}:${home}/.procmailrc:+/usr/bin/procmail
no_verify
no_expn
local_user:
debug_print = "R: local_user for $local_part@$domain"
driver = accept
check_local_user
local_parts = ! root
transport = LOCAL_DELIVERY
I've been seeing a lot more spam sent to "users" that are in my alias
and passwd files (i.e. www-data).
All my real users use procmail for delivery, so I thought maybe I
could remove the "local_user" router and only accept mail for users
with a .procmailrc file.
But testing without the "local_user" router all my users report
"Unrouteable address". Not sure I understand why that happens. All
my local deliveries are reported with R=procmail T=procmail.
What I'd like is if there's an alias that points to a user with a
.procmailrc file, then deliver. Otherwise reject.
And, I'd also like to prevent mail getting delivered to "users" just
because they are listed in /etc/passwd but don't have a .procmailrc
file.
On a related note, my Debian Stable system comes with an /etc/aliases
file that includes entries like:
mail: root
news: root
uucp: root
proxy: root
www-data: root
mailer-daemon: postmaster
I'm not clear, but when does mail get delivered to those? Why would I
ever accept mail for, say, my web server?
