Sendmail question

use a filter via a script
You don't have to do anything for the EXTERN group. Just create the alias in the /etc/aliases file.
___________________________________
For the INTERN group, I would use a script as a filter.
Direct all mail from this alias INTERN into the script. Then if the email address meets your criteria for the xyz.com then allow the email to go. Otherwise, redirect the email back to the sender or send them a standard denial email.
In /etc/aliases, where testscript is your script that checks for the email address. You may have to put the script put in a certain directory for this to work. On my systems it is in /usr/local/bin as a default for sendmail scripts.
Yours may be different.
#vi /etc/aliases
...
...
#Local Aliases
INTERN: "|testscript"
Hope this helps.

NEWS2MAIL(8) System Manager's Manual NEWS2MAIL(8) NAME
news2mail - a channel script to gateway news into email. SYNOPSIS
news2mail DESCRIPTION
news2mail runs as a channel process underneath innd. It is set up as channel feed in newsfeeds, with different mailing lists as funnel entries pointing to it (see below). news2mail uses a config file <pathetc in inn.conf>/news2mail.cf to map mailing list names to email addresses. news2mail causes sendmail to queue the messages for later delivery (to avoid DOS attacks by mass postings). You must run 'sendmail -q' periodically to get the queue processed. CONFIG FILE
The config file format is simple: comments (start with ``#'') and blank lines are ignored. All other lines have two fields on them. The first is the list name and is what innd uses (i.e. the site field of the entry in the newsfeeds file). The second field is the actual email address to send the article to. In the email message, the ``To'' header will have the mailing list name (i.e. the first field) # list-name address big-red-ants@ucsd.edu big-red-ants-digest@ucsd.edu news-software@ucsd.edu news-software-digest@ucsd.edu a set of newsfeeds entries for these lists would be: n2m!:!*:Tc,Ac,Wn*:<PREFIX specified with --prefix at configure>/bin/news2mail big-red-ants@ucsd.edu:rec.pets.redants.*:Tm:n2m! news-software@ucsd.edu:news.software.nntp:Tm:n2m! news2mail strips most article headers from the article before mailing. It leaves: From, Subject Date, Organization and Message-ID in there. It add a To header with the mailing list name in it. HISTORY
