I do this here using fetchmail.
I created public folders on the Exchange system for people to drop Spam, Ham
and False-Positives into.
Create three aliases on your gateway that point to sa-learn, for sendmail
these will work
spamforget: |"/usr/local/bin/sa-learn --no-rebuild --forget"
spamlearn: |"/usr/local/bin/sa-learn --no-rebuild --spam"
hamlearn: |"/usr/local/bin/sa-learn --no-rebuild --ham"
Installed fetchmail on my gateway system and created three .fetchmailrc
files. One for spam, one for ham, and one to forget.
Here's the one I use for spam:
#
# Feeds email from the public spam folder into sa-learn
set postmaster "yourpostmaster"
set no bouncemail
set no spambounce
set properties ""
defaults proto imap
poll mailserver.goes.here proto imap
user "your-nt-domain/your-username/your-mailboxname" pass
"yourpasswordhere"
is spamlearn here
folder "Your\Public\Folder\Info"
keep
fetchall
no rewrite
#
Remove the "keep" if you want it to delete stuff when it's done. I have it
because I have two mail gateways here that both do this one has the keep the
other doesn't.
In your /etc/crontab or in some users crontab on your gateway add something
like
15 */4 * * * your_user /usr/local/bin/fetchmail -f
.fetchmailrc-spam
45 */4 * * * your_user /usr/local/bin/fetchmail -f
.fetchmailrc-forget
55 */4 * * * your_user /usr/local/bin/fetchmail -f .fetchmailrc-ham
This method works great for me. Other people have had problems with it
because their exchange server is changing the original mail headers. Our
doesn't so this works fine other than adding 1 received line to the message.
