Thanks to all who responded - I got so many replies I won't list all of the
names but will summarize the results.

Original Question:

How to set up an e-mail account in Sendmail that allows e-mail to be sent
but not be received for purposes of sending out notices announcements, etc.


There are a couple of ways to do this.

Define an alias for the account in /etc/mail/aliases to /dev/null. It would
look like this in the aliases file:


After that, run the newaliases command to update the database.

You can test if it works by going to the following directory and typing:

/usr/lib/sendmail -bv sendonly

Here is a second method:

Set up procmail. Have procmail (either system-wide or in foo's home
directory) /dev/null any incoming mail destined to foo.

Have a virtusertable block mail destined TO foo.

A sendmail alias of /dev/null for foo.

A cron job which issues a "cat /dev/null >/var/mail/foo" every
"X" number of minutes.

Again, thanks to all who responded.
