Matt Bramble has reported a malicious message which can affect your Declude
processing specifically if you have the AUTOREVIEW      ON  in your
declude.cfg, we would suggest all SmarterMail/Declude setups follow these
instructions:


The problem appears to be in the decoding of a bad subject.   The
problematic subject line is as follows:

 

Subject:=?UTF-8?B?MQ==?==?UTF-8?B?MA==?==?UTF-8?B?MA==?==?UTF-8?B?JSBG?==?UT
F-8?B?cmU=?==?UTF-8?B?ZSBw?==?UTF-8?B?cmk=?==?UTF-8?B?Yw==?==?UTF-8?B?ZSBx?=
=?UTF-8?B?dW90?==?UTF-8?B?ZQ==?==?UTF-8?B?cyBv?==?UTF-8?B?biBob20=?==?UTF-8?
B?ZSB3YXI=?==?UTF-8?B?cmFu?==?UTF-8?B?dHk=?==?UTF-8?B?LVI=?==?UTF-8?B?ZXNw?=
=?UTF-8?B?b25k?==?UTF-8?B?IQ==?=
