The alternative you are proposing is to say that even though SA thinks a mail is not spam (because its only scored 1.0), you are going to use this '1' and add it to you own HMS test well what happens if the SA 'HELO' yest is the score of 1, and then you run HMS 'HELO' test scoring 4 (same test yet scored twice?) You now deem your mail as spam (acheiving 5) when in reality both SA and HMS hasnt REALLY found it as spam at all. Of course this your own HMS test scoring is probably not as fine tuned as the SA scoring rules so is more brute force. ie, maybe SA scores 3.1 (determining as SPAM), and you have your own HMS threshold set to something higher (5 or 6) allowing for your own HMS tests. Furthermore it does this because the rules and its abilities are FAR MORE advanced than any HMS does internally.īy using the SA score if only appropriate when you think SA may have determined as spam (I have the threshold set at 3 which seems to be just right) and yet you want to not FULLY trust it and add HMS tests on to it too. You kow that SA rules add scores in decimal and as negatives such asĪnd as such it collectively determines its spam value. #Spamassassin test installTo install the plugin, apt-get install dovecot-sieve dovecot-managesievedĪnd, we edit /etc/dovecot/conf.d/nf file to configure dovecot to enable the sieve plugin.In my opinion I cant see why you would want to add SA score unless SA has deemed it potential spam.īy using SA you are trusting it and iuts rules to make a judgement: as per your SA configuration, a mail is either deemed as Spam or it is deemed as safe. This plugin helps to use Sieve to read mails. For that, Dovecot wants a Sieve interpreter plugin. Also, we configure Dovecot with a separate Spam folder. Further, this helps in an easy grouping of emails.Ĩ. As a result, all spam emails will have a tag. ![]() Hence, we uncomment the rewrite_header line to modify the Subject lines of emails that are identified as spam. For that, we edit the configuration file /etc/spamassassin/local.cf. Additionally, we configure SpamAssassin to modify emails according to spam checks. Then add the following line at the end of the file. So, we open the file /etc/postfix/master.cf. The next step is to configure Postfix to use SpamAssassin as a filter. As the next step, we change to CRON=1 at the bottom of this file.ĥ. OPTIONS="-create-prefs -max-children 5 -helper-home-dir -username spamd \Ĥ. ![]() After that, we edit /etc/default/spamassassin to configure SpamAssassin as follows. Useradd -g spamd -s /bin/false -d /var/log/spamassassin spamdģ. Then, we set up a user account and group for spamd service. Initially, we install SpamAssassin packages with the following command. Here, let’s see how our Support Engineers install SpamAssassin with Postfix and Dovecot on Ubuntu/Debian server.ġ. Depending on the spam score Spamassassin adds headers to that email to mark it spam. Moreover, Spamassassin can scan incoming emails. Also, this is one of the best solutions to protect the mailbox from the incoming spam mails. Let’s begin by checking the process to integrate SpamAssassin in Postfix and Dovecot server.īasically, SpamAssassin is an anti-spam software. How we integrate Postfix Dovecot SpamAssassin ![]() Today, we’ll see how our Support Engineers make use of SpamAssassin to fight against spam mails. Often the bad configuration may lead to improper spam detection too.Īt Bobcares, we often get requests from our customers to configure SpamAssassin with Postfix and Dovecot as part of our Server Management Services However, configuring mail servers with SpamAssassin may not be easy. Luckily, the Postfix Dovecot SpamAssassin combination helps to protect the mailboxes from the incoming spam mails. Have you ever thought of an effective way to stop spam emails? ![]()
