Hi,

I have released 2.2 final at the usual place:

	http://www.roaringpenguin.com/mimedefang/

Here are all the changes since 2.1:

Major feature enhancements:
- ---------------------------

o Added action_replace_with_url.  This strips out a mail part and replaces
it with a URL.  You can use this to put large attachments on a Web server
and make life easier for POP3 users on the end of a slow modem link.

o Added stream_by_domain to allow administrators to use different scanning
rule sets for different domains.  Very useful if you host virtual domains.

o Added resend_message (used by stream_by_domain) to resend the original
message.

o Added add_recipient and del_recipient functions to add/delete envelope
recipients.

o Added action_notify_administrator to send notices to MIMEDefang
administrator (as suggested by Randy Fox.)

Bug fixes, security fixes, etc:
- -------------------------------

o Do not add X-Scanned-By header if an identical header exists already.

o Name quarantine directories based on time for easy sorting.

o Error messages from the Perl filters are logged to syslog at DEBUG level.
This should make tracking down filter problems much easier.

o If the filter fails, an SMTP "temporary-failure" code is issued.  This is
far safer than the old mechanism of adding an "X-MIMEDefang-Warning:" header
and allowing the mail through.

o Clarified the effect of the "-f" flag in mimedefang manual pages.

o Configure script checks for prerequisite Perl modules.

MIMEDefang 2.2 is the best version yet; I strongly recommend that all
MIMEDefang users upgrade.
