OT: block mail for specific user

[James Pifer]

This is way OT, but I'd rather not get on yet another mailing list. I
want to setup email for one of my kids, but I only want to allow mail
from specific addresses and blocking all others.

I'm running Sendmail with MailScanner. Any way to do what I'm looking
for?

Thanks,
James

man procmailex

Not OT at all. I saw one person suggested procmail which will do the job. 
I prefer doing it a different way. Use the access databse in sendmail. 
Assuming your kid's name is elmo, and you wanted him to be allowed email 
from three different addresses,

To: [e-mail]	REJECT
From: [e-mail]		OK
From: [e-mail]		OK
From: [e-mail]		OK

The advantage is that the mail will be rejected by sendmail before 
reception completes. The disadvantage is that you need to do a bit more 
reading to fully understand it. ;-)

Hm, trying to do this but when I try to send a message to elmo it says
the mailbox is disabled, even though I'm sending from an address that is
marked OK, just like your example. I made the changes using webmin. I
looked at /etc/mail/access and it looks just like your example.

Any thoughts? I'll keep trying.

Also, looks like I can use this to restrict outgoing too? I'd like to do
that as well. Obvious I only want to restrict the kids and not myself.

Thanks,
James

ummm...if you're using postfix for your mail, you'll need to do it in
the /etc/postfix directory instead of /etc/mail

Nope, using sendmail.
