I have set up iRedMail and it is working fine sending and receiving mail.
I am having difficulty getting:

Spam headers to be added to all/any mails (only checked received, not sent)
Spam feels like it is getting through. Hard to tell without the headers from SpamAssassin.
Messages with banned attachments are coming though with the banned attachment intact.

I've tried tweaking various conf settings, but it didn't seem to help. I am the first to admit that I don't know what I am doing, but I am trying.

I found this site to help me debug/validate email system
http://www.emailsecuritycheck.net/

There are seven test mails our server will try to send:
The first mail (1/7) contains a harmless executable attachment. Even though it is harmless, it should be removed (or replaced) by your attachment blocker. Depending on the configuration of your attachment blocker, this mail may never reach you.
The next mail (2/7) contains a harmless executable attachment, the EICAR anti virus test file in a .zip archive. This file should be detected by every virus checker. Depending on the configuration of your virus checker, this mail may never reach you.
The third mail (3/7) is harmless spam message (GTUBE spam signature), and should be detected by every spam filter. Depending on the configuration of your spam filter, this mail may never reach you.
The remaining four mails (4/7 to 7/7) contain attachments disguised in different ways. Even though the attachments are harmless, they should be removed (or replaced) by your attachment blocker. Depending on the configuration of your attachment blocker, these mails may never reach you.

My email system blocked the EICAR message, but the other 6 came through to the client
My postmaster received 1 virus alert, and 5 banned contents alerts.
My postmaster did not get notified of the GTUBE test

I ran grep spam * in /etc/amavis/conf.d to give you info on my current config.

Re: Spam and blocked attachments are getting through

You should check Amavisd log to see whether it detected them as spam or not (it logs into Postfix log file by default).

50-user:$final_spam_destiny = D_PASS;

This setting in file /etc/amavis/conf.d/50-user will continue delivering detected spam to user's mailbox.

Re: Spam and blocked attachments are getting through

OK. Things are looking much better.

I changed 2 parameters in /etc/amaisd/conf.d/50-user to:
$final_banned_destiny = D_DISCARD;
$final_spam_destiny = D_DISCARD;

Then I re-ran the test from
http://www.emailsecuritycheck.net/

For the 7 test messages that they sent:
My test user received 0 messages.
My postmaster received 6 messages. 1 virus alert, and 5 banned contents alert.
My postmaster failed to get notified about the GTUBE test, but that is ok since I wouldn't want to get flooded with spam alerts.

See below for the data from mail.log.

Two issues remain. sa_tag_level_deflt and defang_banned

1) I am still not getting the spam scores inserted in to the header even though I have:
20-debian_defaults:$sa_tag_level_deflt = -100.0

Do I need something else to make this work?

2) I have defang_banned = 1. One of the 7 test files sends an attachment called attach.bat. It was my desire that anything banned would be removed from the message and the rest of the message delivered. Instead the entire message was delivered. Using $final_banned_destiny = D_DISCARD stops the attachment but also the entire message is killed.

I believe killing the message entirely will be fine, but I would like to understand defang_banned. I can envision use cases where valid email disappears, and without any notification, finger pointing and tension could arise.

Thanks for the help

Testing emails were discarded, so you didn't receive them, right? Then how do you know no spam scores inserted in header?

I believe killing the message entirely will be fine, but I would like to understand defang_banned.

It's better to ask in Amavisd mailing list instead: http://www.ijs.si/software/amavisd/#support

Re: Spam and blocked attachments are getting through

This iRedMail install replaced an old mail server I set up from
http://www.howtoforge.com/

I replaced it because my OpenSuse install had become way out of date and was worrying me regarding security updates.
I understand your feelings about dropping OpenSuse, but it was a bummer for me.

In my previous mail server, every mail item delivered to every user had spam headers inserted. Then Thunderbird could use them or not as the user saw fit. And the subject line was rewritten with *** SPAM *** inserted in the front.

In this Debian iRedMail install, no messages get spam headers, or *** SPAM *** inserted in the subject line.

Testing emails were discarded, so you didn't receive them, right? Then how do you know no spam scores inserted in header?

It is true the messages were discarded, but before I made that last change, the messages were delivered intact. No spam headers, and no subject line alteration.

I do appreciate your time in responding
I will check out the link for amavisd support.

Aug 5, 2024: iRedMail-1.7.1 has been released.
