debian: apt-get install sendmail
This is just some info I came across for anyone thats new to sendmail like me.
access_db') to your sendmail.mc, you will need to create your /etc/mail/access file, then run ****make**** once, which will modify the makefile to add rules for the access file. Then, run ****make**** a second time, and it will create the /etc/mail/access.db file from /etc/mail/access - I use this along with FEATURE(blacklist_recipients') for spamtrap addresses, like:
Once the database has been created, you only need to run the makefile once each time you add an entry to the access file.
The self-modifying makefile also works with /etc/mail/virtusertable if you want to use a virtual user table. I use the virtual user table to allow any address at my domain to work, getting forwarded to me; this basically gives me a honeypot, and I can blacklist any address that gets spammed. So far, the only spam hits I've received have been to spamtrap addresses that I've used on USENET posts, which get 553'd before I ever see them.
