How to block (deny) email from ...

DanielC
What is the easiest way to block all mails coming from a particular sender or domain. 
I'm receiving a lot of virus-containing messages from a particular person. The virusscanner intercepts them but it would be easier to just block this person.

Any ideas?

    But can you block individual names?

    Or can you block emails with specific words (not only the extention of an attachment)

    It does not seems wise to block yahoo.com or hotmail.com for everyone behind the firewall...

    There is a way but it requires editing some files on ASL. Look under hacks and do some searches on BB I have seen the solution out there but am not sure where

    Hi Lanman,
    sorry but I found nothing that could handle my problem.
    Here's what I want to do:
    Someone sends (mostly Spammers) Emails to user@mydomain.com and I want to block these mails. 
    The problem is that user@mydomain.com is not in the mime-text of the email that is received (because that are mostly Mailing-Lists). So the Expression filter does not block it. 
    I think I have to configure something in exim that this user is blocked.

    Does someone have an idea?

    To block users or domain edit this file:
    /var/chroot-smtp/etc/exim.blockedsenders

    format like:
    spammer@spam.com
    bigspamhole.org
    spammersrus.edu

    etc.
    Save the file and restart the SMTP daemon.
    /etc/rc.d/smtp restart

    Yeah, but I think he is trying to block an internal user from using the smtp proxy.  The internal network has been specifically ALLOWED.  Is it possible to then can one user?

    Simple, go threaten the user with hellfire unless they desist.  Go to their manager or something.

    It does not seems not to work.

    There is a line in the file /etc/chroot-smtp/etc/exim.conf  that read sender_reject_recipients = @@lsearch*;/etc/exim.blocksenders

    At first sight this looks to point to the wrong directory. (there is no file /etc/exim.blockedsenders)

    Do I need to change the exi.conf file then?

    Thanks

    No, you don't need to change the conf file.
    remember the path is chroot'ed.

    I added a line domainnamesearchengine.net (because most of our spam now comes from a_user@domainnamesearchengine.net) in the exim.blockedsenders file and restarted the smtp but the spam-mail still comes in

    Is there a way to check what the result should be?

    Or do I have to use wildcards?
