If there are any questions, shoot while it's still fresh. My existing mailserver runs on Gentoo Linux, running Postfix, courier-imap, maildrop, Spamassassin and ClamAV, with the mail accounts and aliases handled by. you need to create a file /etc/courier-imap/maildirshared which contains: Though i would get everything marked as spam put into a seperate mailbox instead, so you can check it first before deleting it as you wont. you'll need the ftp extauth script (with a small C program) to incorporate it with QMail/Courier, I'll upload it shortly cmd 'cmd /c perl -S -T -w spamassassin -e < ''' & testfile & ''' > ''' & infile & '''' and set the return code in hMailServer Admin to 5 then it will delete everything that spamassassin thinks is spam.QMail also comes with maildirmake (in /var/qmail/bin), DON'T use it, use /usr/bin/maildirmake instead qmail, disable direct delivery and or forward and use procmail to do it. procmailrc and not deliver directly, you have to modify user's. The final problem is to actually get Qmail to use. procmailrc file, you have to setup an FTP server (I used PureFTPd), write an external auth script for it, setup Ingo to use it and to generate the file with right permissions and such. If youre looking for a bayesian e-mail filter, look at Apache SpamAssassin instead. This is similar to a fuzzy hash where certain parts of the email body are dropped and a md5 hash is generated. The hard part was to get my tagged mails filtered, default Ingo (that's the webmail's filter-making plugin) doesn't filter on mail arrival but when you click on Apply filters, which isn't all that hot solution, I wanted it on delivery which is more natural. The CRM114 program hasnt received any updates since 2010. iXhash can be used to block additional spam. I've setup two global shared IMAP folders (IsSpam and NotSpam) in which my users can move/copy wrongly tagged mails by SA which has a central filter, then a cron job pipes it to sa-learn and we all benefit. To enable delivery via Maildrop, one needs to add these settings into Postfix main.cf: # in /etc/postfix/main.cfįurthermore, we need to add a Maildrop section to master.cf: # in /etc/postfix/master.Finally got this combo working, it was more difficult then I hoped for. This how-to will show you in a few quick step how to setup a Postfix mail server using Dovecot for imap and pop3, clamav and spamassassin to combat viruses and spam and maildrop for delivering the mail to your users. In my description on integrating Maildrop into a Postfix setup with MySQL, I am referring this base installation. Hi, I while back I created a small how-to that I used to setup a mail server at work, I have also used the same how-to on my own server. How to Integrate Maildrop for Spam Filtering into Postfix MySQL If any header line starts with “X-Spam-Flag: YES”, maildrop delivers to the spam folder. Afterwards, it matches mail header lines against SpamAssassin’s X-Spam-Flag marker. If not, it creates one and adds a folder subscription line to a Courier-IMAP control file. Here, Maildrop first checks if a spam folder already exists under the virtual user directory. `echo "INBOX.$SPAMFOLDER" > "$VHOME/courierimapsubscribed"` Intelligent filtering with Qmail, SpamAssassin, and Maildrop. `/usr/bin/maildirmake -f "$SPAMFOLDER" "$VHOME"` folder and adding new spam signatures to SpamAssassin. I installed SpamAssassin last Friday and all appeared to be working well I created a test email account for myself on the server, and send myself some emails which were not flagged as spam (correct). We're using Postfix for our MTA, and also using MailDrop (for local delivery, right). In more advanced setups, Maildrop performs pattern matches on email header lines as well as folder administration: # Sample maildroprc with spam folder We have a dedicated server, which is running Fedora. It then stores mails from STDIN under “$VHOME”. Let’s look at a basic Maildrop configuration file: # Sample maildroprcįrom this minimal configuration, Maildrop reads the location of its logfile and the Maildir output folder as specified in the “$VHOME” environment variable. These procmail rules, for example, call DCC and Spamassassin. However I wanted to have spam filtering even for those customers who choose to use email clients such as evolution, mozilla, or Outlook Express. I am quite impressed with all the nice plugins including spamassassin and bayesspam. Courier-Maildrop receives emails from standard input and stores them in Maildir format according to instructions from a maildroprc configuration file. to do delivery time filtering is to call filter programs from procmail or maildrop.
