    I have a web server which is run a postfix email server and is controlled by ISPConfig.

    My email domain: mydomain (dot) com

    Also, I wrote some services on Python which is run on the same server and in some cases sends emails with zip files from: service_1(at) to: collector(at)

    It worked well. But one week ago I found that I no longer receive emails on collector(at) I started an investigation and found that in the mailbox service_1(at) many emails with the subject:

    BANNED contents from you (​

    With body:

    Delivery of the email was stopped! The message has been blocked because it contains a component (as a MIME part or nested within) with declared name or MIME type or contents type violating our access policy.​


    I.e. for some reason postfix no longer delivers email to collector(at) from service_1(at) I also checked it with the simple python script.

    I did not make changes on any of the server configs, so I suppose that happened due to some automatic rules. I also checked all (as I think) options on the ISPConfig control panel, but do not find any allusion to the arisen problem.

    Then I checked the mail server log and found that amavis blocking emails:

    Aug 12 12:34:23 mydomain amavis[29034]: (29034-07) Blocked BANNED ( {BouncedInternal,Quarantined}, ORIGINATING LOCAL []:37112 [] service_1(at) -> collector(at), quarantine: d/banned-dYWbCJmcq6Xq, Queue-ID: B58E381365, Message-ID: 20220812123348.B58E381365(at)mail(dot)mydomain(dot)com, mail_id: dYWbCJmcq6Xq, Hits: -, size: 122404, 34820 ms

    Is it possible to add a rule to allow pass any content from one internal mailbox to another internal mailbox?

    Have you tried adding such whitelist? What happened? In ISPConfig panel EMail tab there is spamfilter whitelist and Postfix whitelist.
