People who are using daily email for genuine purposes may get adversely affected by too much spam. ![]() ![]() We really need to be double sure about spam because Unsolicited Bulk Spam can crowd up your clients’ mailboxes. It filters the inbound messages and keeps your users protected from the spam!Īn incoming filter is very necessary because ultimately CyberPanel is a web-hosting control panel, and it will be available to end user clients as well. They use a variety of spam-detection techniques which include but are not limited to matching blacklists, online databases, DNS-based scoring, checksum-based spam detection and much more! It is a content filter and gives email a score based on its “spaminess” (that is, the likelihood that the email’s content is spam), the higher the score, the higher the possibility that the email is spam. What is SpamAssassin?Īpache SpamAssassin is a project of the Apache Foundation. SpamAssassin will also be integrated into CyberPanel very soon by our developers, but until then, this is a manual method of doing so. Please note that CyberPanel has built-in support for DKIM creation and TLS encryption in email. Well, this tutorial is for you! This article will explain how to install and configure SpamAssassin on a server with CyberPanel installed so that your email services are spam proof. ![]() In our infrastructure we have a Proxmox Mail Gateway 7.1.4 server deployed in front of our mail server to control incoming mail, we are having problems filtering spam emails, we edit the rules to control such emails and we see that some continue to pass, when we see the tracking of these emails, the score that SpamAssassin gives to said email exceeds level 10 and it delivers said email anyway.Īntispam postfix/cleanup: EFD7E1018DD: message-id=Īntispam postfix/qmgr: EFD7E1018DD: from=, size=12983, nrcpt=1 (queue active)Īntispam pmg-smtp-filter: 1018EC63061C1852C20: new mail message-id=#012Īntispam postfix/smtpd: disconnect from unknown ehlo=1 mail=1 rcpt=1 data=1 quit=1 commands=5Īntispam pmg-smtp-filter: 1018EC63061C1852C20: SA score=13/5 time=6.282 bayes=1.00 autolearn=no autolearn_force=no hits=BAYES_99(3.5),BAYES_999(0.2),HTML_MESSAGE(0.001),HTML_MIME_NO_HTML_TAG(0.377),KAM_2TLD_PROBLEMS(2),KAM_DMARC_STATUS(0.01),KAM_SA_ZA_ABUSE(4.5),MIME_HTML_ONLY(0.1),RDNS_NONE(0.793),SPF_HELO_PASS(-0.001),SPF_PASS(-0.001),T_SCC_BODY_TEXT_LINE(-0.01),URIBL_BLACK(1.7)Īntispam postfix/smtpd: connect from localhost.localdomainĪntispam postfix/smtpd: A8572101DCD: client=localhost.localdomain, orig_client=unknownĪntispam postfix/cleanup: A8572101DCD: message-id=Īntispam postfix/qmgr: A8572101DCD: from=, size=13209, nrcpt=1 (queue active)Īntispam pmg-smtp-filter: 1018EC63061C1852C20: accept mail to (A8572101DCD) (rule: Whitelist User)Īntispam postfix/smtpd: disconnect from localhost.localdomain ehlo=1 xforward=1 mail=1 rcpt=1 data=1 commands=5Īntispam pmg-smtp-filter: 1018EC63061C1852C20: processing time: 6.353 seconds (6.282, 0.049, 0)Īntispam postfix/lmtp: EFD7E1018DD: to=, relay=127.0.0.1:10024, delay=6.7, delays=0.36/0/0/6.4, dsn=2.5.0, status=sent (250 2.5.0 OK (1018EC63061C1852C20))Īntispam postfix/qmgr: EFD7E1018DD: removedĪntispam postfix/smtp: A8572101DCD: to=, relay=:25, delay=0.02, delays=0/0/0.01/0.01, dsn=2.0.By now we have ensured all of our emails are encrypted via TLS using Let’s Encrypt verified certificates, and we’ve also set up DKIM so that the email recipients can authenticate the messages easily and at a much better rate.īut what about SPAM? What about incoming unsolicited bulk mail spam going from server to server? You sure would not want your server and your clients to be a victim of it, right?
