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

Thanks,

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 acc=
ess db.

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

Also you can check the comp.mail.sendmail=20
newsgroup. A quick search produced some very similar
questions:=20

ail.sendmail&q=3Ddeny+local+user+sending+mail&qt_g=3D1&searc hnow=3DSear=
ch+this+group.
Pay particular notice to Claus Aßmann's replies.

Regards
Carl

Re: sendmail - dany a user to send email

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
