Spam Submission

submit_spam is a spam and ham submission processor. It's copyright under the GNU General Public License.

Download/view it here (v0.3) or changelog.

To install and use:

Copy the file into an appropriate place, such as /usr/local/sbin.
Configure your MTA as appropriate:
- For Sendmail:
  1. edit your /etc/aliases file to include this line:
```
spamassassin:   |/usr/local/sbin/submit_spam
```
  2. and recompile your aliases database:
```
newaliases
```
- For Postfix, the above technique would run the script as the nobody user for security reasons. It's unlikely that spamassassin is being run as this user, so instead we define a transport to run the script as the appropriate user. In this case, the amavis user.
  1. edit /etc/postfix/master.cf to define a new transport by adding these lines:
```
    # spam submission
    submitspam      unix  -       n       n       -       1       pipe
      flags= user=amavis argv=/usr/bin/perl -T /usr/local/sbin/submit_spam ${user}

    
```
  2. edit /etc/postfix/transport to use the new transport for spam submissions by adding this line:
```
    spamassassin@laidman.org    submitspam:localhost
    
```
  3. remake the transport database:
```
postmap /etc/postfix/transport
```
  4. restart postfix
```
postfix restart
```
Submit your spam/ham: In Outlook or Thunderbird, create a new email addressed to spamassassin@yourspamserver.com.
- To submit spam, set the subject to spam.
- To submit ham, set the subject to ham.
Attach one or more messages of the stated ham/spam type. Do this by dragging the ham or spam messages into the new email. Do not cut-paste into the message as this will not preserve the header information, which is vital for some of the spam tests.
You should receive an email telling you that the messages were submitted, listing the subject lines.

This has been tested under Postfix, and works for sendmail too but only in theory. Feedback is sought on this and any other transports that work.

To ensure this is working, run the following command before and after submission and compare the differences. It needs to be run as the user with the spamassassin database.
