Amavis is an open-source content filter solution for electronic mail. It implement mail message transfer, decoding, processing, checking and interfacing with external content filters to provide protection against spam, viruses and other malware. It may be considered an middleware between a mailer (MTA) and one or more content filters.
In some cases amavis mai block emails due to False negative checking. In this cases we will need to manually deliver emails to receivers.
Let’s take a look to the following example where amavis generated False Negative:
Subject: BANNED contents (.exe,.exe-ms,[trash]/0000.dat) in mail TO YOU from
<[email protected]>
BANNED CONTENTS ALERT
Our content checker found banned name: .exe,.exe-ms,[trash]/0000.dat in an email to you from: [email protected]
Content type: Banned
Our internal reference code for your message is 103023-12/3THZOQo_UEhw
The message has been quarantined as: F/banned-3THZOQo_AUfdThese e-mails can be released and delivered from the quarantine when needed.
This can be done with the tool named amavisd-release:
amavisd-release F/banned-3THZOQo_AUfdAlso this e-mail can also be sent to another user using the following command:
amavisd-release F/banned-3THZOQo_AUfd [email protected]Looking to improve your email infrastructure or anti-spam policies?

Thank you for posting this. This is the first time my amavis has quarantined an email. And I was searching all over for what should be an easy process. This post allowed me to release the needed email within seconds.
