11/11   I'm trying to configure a sendmail server to allow legit Berkeley
        students to use it as an smtp server but not allow spam.  Is there
        a way to do this?  It seems like uclink4 allows external ISPs to
        utilize it as an outgoing mail server while filtering out spam
        somehow.
        \_ Isn't there a way to look at the return address and make sure
           that it's coming from Berkeley?
        \_ set the rberkeley ip address ranges into your relayok file.
        \add something like FEATURE(access_db, dbm -o /etc/mail/access)dnl
        and then add 128.32 RELAY or something like that or more risky but
        more flexible building with: FEATURE(relay_local_from)dnl
        will will mail as long as a local domain smtp sender is specifed
        or "faked". this doesnt impact spam filtering but might allow relaying.
        really you are more likely to get blacklisted for this than used as a
        relay. --psb
        \_ You're much better off using SMTP Authentication, or for the brave,
           Sendmail/TLS then IP range based relaying.  There are quite a few
           hacks involving watching pop/imap logs and editing the realyok file
           but they are pretty damn kludgy.  And I don't know if I would use
           uclink4 as a good example of how things should be run.

9/9     What should outbound mail server be when reading mail from soda

        \_ It's <DEAD>mail.csua.berkeley.edu<DEAD> (same as for incoming mail).

11/18   Say I've written a pcap-based program which pulls out the message
        body of unencrypted SMTP sessions and writes those into file1 file2
        file3 ... fileN. Is there a simple way to get a spam-score for
        each of those [based on message body, not SMTP headers, sender
        reputations etc]. I'd like to have a program warn me if some
        IP address inside my institution starts sending say >10 suspect

7/14    Help sendmail experts. I forward email from my own domain to
        http://gmail.com. I have never had any problem until recently. The problem
        happens only when eBay sends an email to my domain (as
        member@ebay.com). I receive the mail on my domain/my machine, and
        when it tries to forward to gmail, I get the following:
         Diagnostic-Code: X-Postfix; host <DEAD>gmail-smtp-in.l.google.com<DEAD>[w.x.y.z]

1/28    When I run Thunderbird to use my soda mail, I can read mail but I can't
        send.  It gives an error "Sending of message failed.  The message
        could not be sent because connecting to SMTP server
        <DEAD>mead.CSUA.Berkeley.edu<DEAD> failed. ......"  Is there some special setup
        that I need to configure in order to send mail?  Thanks.
        \_ Just use your ISP's SMTP server to send mail. Soda probably
