To all users of eFa,

As you may have noticed there hasn't been any development lately on eFa. I have made the decision not to continue. I feel you should all know so that you can plan ahead accordingly.

eFa 5 will likely continue to work as long as Redhat Enterprise Linux 9/CentOS 9 and other ...

There is a spamassassin results cache database in MailScanner. You can

Code: Select all

sudo rm /var/spool/MailScanner/incoming/SpamAssassin.cache.db

and

Code: Select all

sudo systemctl restart mailscanner

to reset it.

You can add the bank's domain to /etc/sqlgrey/clients_fqdn_whitelist.local and run

Code: Select all

sudo update_sqlgrey_config

Thank you for bringing this to my attention. I will drop this configuration from postfix for new installations since it is not recommended. For existing installations I'll see if I can add the return code range to the definition.

Are you releasing this message to your mailserver or to someone out on the Internet?

:text-welcomewave:

If you use two of them you get the added flexibility of customizing your inbound and outbound filtering separately and not have to worry about making your customizations distinguish between inbound and outbound mail flows.

On the other hand, you would have to manage two boxes ...

This is expected behavior.

I looked at the queue logic in MailWatch and can't figure out how you are getting this warning.

In /etc/MailScanner/MailScanner.conf, what is the value for the following:

MTA
Incoming Queue Dir
Outgoing Queue Dir

In /var/www/html/mailscanner/conf.php:

MS_CONFIG_DIR

This could be MailWatch trying to monitor the queues, but I'm not sure why it would be trying to use sendmail for that. Does it only log when the MailWatch UI is open for about every 30 seconds?

Yes, you can. What you need is a ruleset.

Create a new file in /etc/MailScanner/rules such as spamactions.rules

Define your rules in the file, using tabs to separate fields. Be sure to look at your Spam Actions setting in MailScanner.conf to see what parameters you are using in case you need to ...

/var/www/html/mailscanner/conf.php

Code: Select all

define('QUARANTINE_MSG_BODY', 'Please find the original message that was quarantined attached to this mail.

Regards,
Postmaster');

I'd like to know how "hash:/etc/postfix/transport" ended up here.

mynetworks is initialized out of the box as:

eFa-base-5.0.0-1.eFa.el9.noarch
postfix-config-5.0.0.sh, line 35:

Code: Select all

postconf -e "mynetworks = 127.0.0.0/8 [::1]/128"

Delete the file, should go away.

Please test the following:

Change the following line in /etc/mail/spamassassin/mailscanner.cf:

From:

Code: Select all

bayes_store_module               Mail::SpamAssassin::BayesStore::SQL

To:

Code: Select all

bayes_store_module               Mail::SpamAssassin::BayesStore::MySQL

Report back results.

I am able to reproduce the same behavior.

sudo su - postfix -s /bin/sh -c "spamassassin -D bayes -t < /var/spool/MailScanner/quarantine/20241110/spam/4XmZWK3SLgzcDDsV"

Run #1

Nov 11 21:38:24.182 [2892651] dbg: bayes: tokenized header: 62 tokens
Nov 11 21:38:24.183 [2892651] dbg: bayes: tok ...

Given that bayes is doing this unpredictable behaviour for you it is essentially unreliable and useless. I am going to populate bayes and try to reproduce the same behaviour on my end to continue troubleshooting with you.

I reached out for help from spamassassin on IRC and they want us to:

1) Try ...

Uhhhh.... :crazy: :crazy: :crazy: :crazy:

Do me a favor, can you temporarily disable SELinux and run some more tests?

Can you confirm that bayes autolearning is off in the context of the postfix user? (see below)

Do you have a /etc/MailScanner/spamassassin.conf that is a regular file and has a ...

This is pretty much it.

Yeah, if you change the cron job, you'll have to be mindful that an update to MailWatch could potentially add the default cron job back to cron.daily.

What happens if you execute spamassassin as the user that MailScanner runs as?

Code: Select all

sudo su - postfix -s /bin/sh -c "spamassassin -D -t < msg"

To ways to potentially resolve.

One is to remove the recipient address validation cache. (best)

sudo mv /var/lib/postfix/verify_cache.db /var/lib/postifx/verify_cache.db.bak

Another is to disable recipient address verification using eFa-Configure (under mail settings) or adjusting the postfix ...

This option enables validation via opendkim and opendmarc. Enabling signing for opendkim requires additional setup.

Setup should be the same as in previous versions, so those posts should still apply.

You should get to eFa4 first...

Looks like appstream was moved to vault.

Give this a try:

You are getting a service unavailable. Is your milter functioning properly? msmilter must be running and available on port 33333.

Sounds like you have a mail loop occurring in that direction somehow. I'm not sure why with the information you provided. You may need to check your /etc/postfix/transport file and see if it makes sense for both servers.
