Smtp spamassassin6/7/2023 ![]() # smtpd deamon for amavisd-new to send mails back to postfixĪs amavisd-new will send alert messages, the alias should be configured to send those messages to root or some other recipient. As well as as some for the amavisd-new daemon itself. To allow amavisd-new to send them back to postfix, we need to add additional configuration. The above configuration will send the emails to amavisd-new. Add a line with “-o content_filter=smtp-amavis::10024” directly underneath it. In the /etc/postfix/master.cf configuration file you will find a line for the smtpd. This is done by adding a line of parameters to the smtpd. ![]() Configuring PostfixĪmavisd-new needs to be integrated into postfix to receive the unfiltered emails from the postfix queue. If you have both repositories installed, make sure you have configured yum repository priorities with yum-plugin-priorities to avoid errors during installation and later system updates via “yum update”. Here you can find details about the error message and a temporary solution. yum install spamassassin amavisd-new clamav clamd pyzor perl-Mail-SPF perl-Mail-DKIM postgrey tmpwatch lzopĪt the time of writing, I have noticed problems while installing amavisd-new while having the “epel” repository installed, but the package is available from the rpmforge repository as well. They include Postgrey policy server implementing greylisting, amavisd-new as a wrapper between postfix and other components like Spamassasin as the spam filter, ClamAV as the virus scanner, and SPF and DKIM libraries. The following commands will install the required components for this setup. After the emails are checked, they are sent back to postfix for delivery. There, the emails get checked for viruses and spam. 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.In the setup described in this post, postfix passes incoming mail on to amavisd-new.
