quote rfc2821 section 4.5.2:
" - Before sending a line of mail text, the SMTP
client checks the first character of the line. If it is
a period, one additional period is inserted at the
beginning of the line."
<?php
$part =
"=41=42=43=44..=45=46=47=61=62=63=64=65=66=67=68=30=31=3
2=33=34=35=36=37\n..=41=42=43=44=45=46=47=61=62=63=64=65
=66=67=68=30=31=32=33=34=35=36=37";
$part = quoted_printable_decode($part);
echo "Expected result\n";
echo "ABCD..EFGabcdefgh01234567
.ABCDEFGabcdefgh01234567";
echo "\n\nGot result\n";
echo $part;
echo "\n\n";

AFAIK it only doubles the . if it's the ONLY character on a line. Can
you quote from the RFC to prove that's not the case?
Also, please provide a selfcontained example (that we can copy & paste
& run) to show why you think there is a bug.

Description:
------------
quoted_printable_decode() does not handle lines starting
with "..".
smtp appends a period to the beginning of a new line for
lines already starting with a period. (per rfc2821, this is
to distinguish between the single period used for marking
the end of a message). This is reproducable every time.
I also saw the function make a ".." in the middle of a line
as "." where what was really wanted was "..".
<?php
/* here is my temporary fix, but also further explains the
problem */
/* 1. Replace all of the \n\.\. with \r\. */
$part = preg_replace('/(\n)\.\./is','$1.',$part);
/* 2. Replace all of the .. with =2E. */
$part = preg_replace('/\.\./is','=2E.',$part);
/* 3. Decode print quotable */
$part = quoted_printable_decode($part);
echo $part ;
?>

$part = quoted_printable_decode($part);
