MIMEDefang Email Scanner 2.79

Posted Sep 26, 2016

Authored by David F. Skoll | Site mimedefang.org

MIMEDefang is a flexible MIME email scanner designed to protect Windows clients from viruses. Includes the ability to do many other kinds of mail processing, such as replacing parts of messages with URLs. It can alter or delete various parts of a MIME message according to a very flexible configuration file. It can also bounce messages with unacceptable attachments. MIMEDefang works with the Sendmail 8.11 and newer "Milter" API, which makes it more flexible and efficient than procmail-based approaches.

Changes: Add the --data-dump option to scripts/mimedefang-util. Improved Postfix compatibility by trying to get QueueID after first RCPT command, and if not found, at the EOH milter phase. Various other updates.

MIMEDefang Email Scanner 2.74

Posted May 29, 2013

Authored by David F. Skoll | Site mimedefang.org

MIMEDefang is a flexible MIME email scanner designed to protect Windows clients from viruses. Includes the ability to do many other kinds of mail processing, such as replacing parts of messages with URLs. It can alter or delete various parts of a MIME message according to a very flexible configuration file. It can also bounce messages with unacceptable attachments.

Changes: A new "action_add_entity" function allows you to add a pre-built MIME::Entity to the message. A new "load1" command shows the load in a more convenient format than the older "load" command. Additionally, "watch-multiple-mimedefangs.tcl" takes advantage of load1 to display load graphs in a more useful format. Finally, quite a few Perl deprecations, bugs, and documentation errors were fixed.

MIMEDefang Email Scanner 2.73

Posted Jan 24, 2012

Authored by David F. Skoll | Site mimedefang.org

MIMEDefang is a flexible MIME email scanner designed to protect Windows clients from viruses. Includes the ability to do many other kinds of mail processing, such as replacing parts of messages with URLs. It can alter or delete various parts of a MIME message according to a very flexible configuration file. It can also bounce messages with unacceptable attachments. MIMEDefang works with the Sendmail 8.11 and newer "Milter" API, which makes it more flexible and efficient than procmail-based approaches.

Changes: This release contains three new features. A new -G option causes files created by mimedefang to be group-readable and sockets to be group-readable/writable. The multiplexor snoops in on communications and saves the Sendmail queue-ID for logging purposes. It logs the queue ID when logging a slave's STDERR. Finally, MIMEDefang passes along the client port number, server IP address, and server port number to all filter functions. In addition to the three new features, there are several minor bugfixes.

MIMEDefang Email Scanner 2.72

Posted Jul 21, 2011

Authored by David F. Skoll | Site mimedefang.org

MIMEDefang is a flexible MIME email scanner designed to protect Windows clients from viruses. Includes the ability to do many other kinds of mail processing, such as replacing parts of messages with URLs.

MIMEDefang Email Scanner 2.69

Posted Jun 17, 2010

Changes: This release contains mostly minor cleanups and bugfixes. However, a new "-y" option for mimedefang-multiplexor allows you to limit the number of concurrent "recipok" commands on a per-domain basis. This can avoid a DoS situation if one domain has a slow or down SMTP call-ahead server.
