Hi,
is there a way in sendmail to deny a user to send email, allowing she to 
receive emails?

Thanks,
Luca

Luca,

Have a look at http://www.sendmail.org/m4/anti_spam.html#access_db

If the user has a static IP address you could just REJECT it in the access db.

You could also use SMTP AUTH and not give the user access.

Also you can check the comp.mail.sendmail 
newsgroup. A quick search produced some very similar
questions: 
http://groups.google.com/group/comp.mail.sendmail/search?group=comp.mail.sendmail&q=deny+local+user+sending+mail&qt_g=1&searchnow=Search+this+group.
Pay particular notice to Claus Aßmann's replies.

Regards
Carl

Hi,

       The easiest way I can think of to do this is to add a line in
your access file (usually /etc/mail/access) like:

From:user@mydomain.com REJECT

but, depending on how you authenticate users, it can be bypassed quite
easily.  If you do try that method, don't forget to rebuild the access
db (makemap hash /etc/mail/access < /etc/mail/access).

Cheers

Adam
